E-cigarette, or Vaping Product, Use Associated Lung Injury EVALI > Fact Sheets > Yale Medicine
There is a web of policy approaches to these issues at all levels of government, including the federal, state, local and international level. While some evidence supports the use of e-cigarettes as quit devices, recent research suggests that their efficacy for quitting is likely overstated. Truth Initiative is America’s largest nonprofit public health organization committed to making tobacco use and nicotine addiction a thing of the past. This includes owners of vehicles from which e-cigarette products are sold and any person who sells e-cigarettes on the internet or by telephone or mail order.
But levels are usually low and generally far lower than in tobacco cigarettes. Some of the harmful substances emitted in secondhand e-cigarette aerosols are similar to those in secondhand tobacco smoke. However, more research is needed to fully understand emissions from e-cigarettes and their impact on human health.
The lawsuits claim the company marketed nicotine products to minors and Juul devices led to serious health problems. Lawyers expect people to file more Juul lawsuits in the litigation as time passes. The trendy e-cigs appeal to young adults and teens who often don’t realize Juul products are e-cigarettes or contain nicotine. Public health researchers have found teens using the term “juuling” instead of “vaping” to distinguish Juul from other e-cigs even though the two activities are the same. E-cigarettes deliver a liquid to users as a vapor instead of a harsher smoke.
However, study authors themselves caution that leaving both mint and menthol on the market undermines the purpose of removing flavors — which is to prevent kids from using e-cigarettes at all. Consumers need to consistently know what they are getting and whether it is safe — particularly from a product designed to deliver chemicals by frequent inhalation. The growing evidence of potential health risks and lung injuries related to e-cigarette use has led researchers to question whether e-cigarettes are safer than combustible cigarettes. All tobacco products, including e-cigarettes, pose a risk to the health of the user.
More adults 18 to 24 years old used e-cigarettes (11.0%, or roughly 3.4 million people) compared with adults 25 to 44 (6.5%) or 45 and older (2.0%). In 2022, 2.55 million U.S. middle and high school students currently used e-cigarettes. Promoted as a “satisfying alternative to cigarettes,” JUUL is putting a new generation of youth at risk of nicotine dependence and future cigarette use.
We also review and share e-cigarette use data and trends and tailor our education efforts accordingly. Most e-cigarettes contain nicotine and their repeated use can lead to nicotine addiction or increase the user’s risk of addiction. Some e-cigarette brands contain nicotine salts to mask the harshness of nicotine and make it more palatable. As of 2018, all tobacco products must bear the required nicotine addictiveness warning statement on product packages and advertisements in order to warn consumers about the presence of and addictive nature of nicotine. In short, the ingredients in e-cigarette liquid have caused users health problems. The health effects of e-cigarettes are still being studied but nicotine addiction, harmful chemical additives, battery explosions causing injury, acute nicotine poisoning and vaping related lung injury have all been linked to use of e-cigarettes and vaping.
But it’s undeniable that they have less conventional carcinogens compared to oral tobacco products, like chewing tobacco and whatnot. About ORCA-V1The Phase 2 ORCA-V1 trial evaluated 160 adults who used e-cigarettes on a daily basis at five clinical trial locations in the United States. ORCA-V1 participants were randomized to receive 3mg cytisinicline three times daily or placebo for 12 weeks in combination with standard cessation behavioral support. The dose and administration of cytisinicline in the ORCA-V1 study is identical to that used in the Phase 3 registrational trials for smoking cessation. ORCA-V1 was supported in part by the National Institute on Drug Abuse (NIDA) of the NIH through grant funding which was awarded in two phases totaling $2.8 million. “A proliferation of establishments selling electronic smoking devices or electronic smoking device paraphernalia, particularly when concentrated geographically, can have a negative impact on public health, safety and welfare,” the moratorium said.
The tobacco industry profits from destroying health and is using these newer products to get a seat at the policy-making table with governments to lobby against health policies. The tobacco industry funds and promotes false evidence to argue that these products reduce harm, while at the same time heavily promoting these products to children and non-smokers and continuing to sell billions of cigarettes. Most e-cigarettes have a battery, a heating element, and place to hold a liquid (such as a cartridge or pod). The e-liquid usually contains nicotine, flavorings, and other chemicals.
You may have heard different things in the media about the side effects of vaping. This page gives an overview of what we know so far about how vaping can affect your health. Our information relates to legal e-cigarettes – ones that are registered with the UK Medicines and Healthcare products Regulatory Authority (MHRA). Prohibiting e-cigarette use inside or near buildings, vehicles and other enclosed spaces is the only way to eliminate exposure to secondhand e-cigarette aerosol and health risks that may come with it.
Founded in 1913 as the Harvard-MIT School of Health Officers, the School is recognized as America’s oldest professional training program in public health. Vaping has become an epidemic among young people in the United States. They also contain toxins that can damage your lungs and overall health. One of the reasons why the e-cigarette epidemic among young people is so troubling is that e-cigarette use seems to lead to the use of traditional cigarettes.
Vape aerosols are not just harmless water vapors that are inhaled and exhaled (as marketed). Vape aerosol exposure is unsafe and contains chemicals, metals (i.e., lead, nickel), and other particles that can interfere with lung development and health. Vape aerosols may also increase the risk of heart disease, lung cancer, and asthma complications. E-cigarettes are harmful for youth, young adults, and pregnant women. The nicotine in e-cigarettes is harmful for developing babies, and can lead to addiction and harm brain development in children and young adults into their early 20s. Although there is still much to learn about e-cigarettes, the evidence is clear that the harmful health effects of using e-cigarettes means teens and young adults should not use them.
Electronic cigarettes were first developed in the early 2000s and introduced to the U.S. market around 2007. Moreover, vaping could serve as a gateway to cigarette smoking, which continues to be a major cause of preventable death globally. Usage rates among different races also varied, with white teens showing the highest increase in vaping rates. Furthermore, a severe lung condition has been linked to vaping, particularly due to the use of vitamin E acetate, an additive in some THC-containing e-cigarettes.
But if a project is particularly stressful (or just slightly vexatious lost vape ursa nano, any excuse will do), my sleek little e-cig is just sitting in my bag at my feet. Like a never-ending pipe, you don’t know when you’ve had enough, when you’ve had a cigarette’s worth of nicotine. One quick puff to slay your stress can turn into one puff every few minutes ijoy vape sd mode, then whenever I get the slightest urge. While saturated fat and alcohol still have their supporters, nobody is rushing to cigarettes’ defense.
The 966 respondents who had never vaped more often believed that e-cigarette waste was dangerous to throw in trash compared to the 1,083 respondents who had vaped at least once (81.4% vs. 71%). Fewer of those who had vaped at least once (79.3%) believed that e-cigarettes contained toxic substances compared to those who had never vaped (89.6%). And the burden is 100% on the company, by law, to demonstrate that the marketing of their product is appropriate for the protection of the public health. In response to the burgeoning e-cigarette market and concern over youth using the products, the FDA in 2020 ordered most flavored vape pods off the market.
Vitamin E acetate was present in bronchoalveolar-lavage (BAL) fluid in 48 out of 51 EVALI patients from 16 states, but it was not found in BAL fluid from the comparison group of 99 healthy individuals. E-cigarettes are threatening to addict a new generation to nicotine. E-cigarette use among young people lost vape thelema, many of whom were not smokers in the first place, has skyrocketed in recent years. Nearly 20% of high school students, one in five, use e-cigarettes, according to the National Youth Tobacco Survey. Young people who use e-cigarettes are also more likely to start smoking cigarettes than their peers who do not vape. The FDA has also reported that, among current youth users of e-cigarettes, 97% used a flavored e-cigarette in the past month.
Even if you don’t think your kids vape, talk about it with them anyway so they know it’s unhealthy. Vaping is the inhaling of an aerosol (mist) created by an electronic cigarette (e-cigarette). To inform this work and evaluate the effectiveness of policy, the CDC Foundation is collecting and analyzing information about e-cigarette sales, teen e-cigarette use, and teens’ attitudes about the epidemic. Children are exposed to e-cigarette advertising online and on TV, in magazines and billboards. Although it is illegal for e-cigarettes to be sold to youth under age 21, they can be ordered online. Drop the Vape also directs users to the New York State Quitline for free and confidential quit-coaching via telephone, internet, and text, and free starter kits of nicotine replacement therapy (NRT) for eligible New Yorkers.
Although PG and glycerol are the major components of e-liquids other components have been detected. Of note, the analysis identified formaldehyde, acetaldehyde and acrolein [4], 3 carbonyl compounds with known high toxicity [63,64,65,66,67]. While no information was given regarding formaldehyde and acetaldehyde concentrations, the authors calculated that one puff could result in an acrolein exposure of 0.003–0.015 μg/mL [4].
This variation makes it difficult to issue overall public health recommendations about the category and demonstrates the huge and long-standing need for pre-market review of these products. We also note the frequently cited claim from Public Health England that e-cigarettes are definitively — 95% — safer than traditional cigarettes. First, this analysis was originally conducted in 2013, prior to recent research on health effects of vaping. Moreover, further analysis into the original research finds that the evidence for such a statistic remains unclear and not fully comprehensive, among other concerns about author and funding conflicts of interest. A priority of the New York State Tobacco Control Program is to prevent the initiation of tobacco use, including combustible tobacco and electronic cigarettes, by youth and young adults.
The Ministry of Finance would instruct customs to manage the transportation of e-cigarettes through the border, and to tackle smuggling. The data about high school students in the new report is from the 2019 Alaska Youth Risk Behavior Survey, a system of anonymous questionnaires sponsored by the U.S. Of the three bills approved by the committee Monday, two deal directly with enforcement and penalties. One bill, A2388, would require vape retailers to be inspected at least twice every year to see if they are selling illegal products.
Vapes are often viewed and marketed as a safe alternative to smoking. A 2015 study in the Journal of the American Medical Association found that teens who took up vaping were three times more likely to start smoking within six months compared to teens who didn’t vape. A Yale University study in 2018 found the switch from vaping to tobacco cigarettes could happen in as little as one month.
There are currently 78 licensed tobacco retailers in unincorporated Sonoma County, representing over 20% of the total tobacco retailers throughout the county, including cities, the county said. Given these alarming trends, the researchers advocate for targeted interventions to address the rising vaping rates among adolescents. They suggest mass media campaigns and peer interventions to counteract the social norms that promote such risky behaviors. By 2019 lost vape ursa, this figure had jumped to 7.2% – more than a threefold increase.
These results underscore the rationale for the implementation and enforcement of public health policies tailored to young adults. We know nicotine and other ingredients in e-liquids can hurt your body and we still don’t know what long-term health problems vaping could cause. There are online resources, texting and phone services and apps that connect you with real people to help you on your journey to kick the habit. People usually think vaping isn’t as bad as cigarette smoking, but the mist you breathe in still has nicotine and other harmful chemicals in it. Vaping isn’t safe and can cause health problems, including life-threatening lung injuries.
Compared with other race/ethnicity groups, Hispanics were the least likely to quit and Blacks were the most likely to continue using banned flavors after the ban. Respondents were both less likely to quit e-cigarette use and more likely to continue using banned flavors if they had used e-cigarettes for a greater amount of time or had weaker intentions to quit before the ban. Respondents who used e-cigarettes because of the flavor were more likely to continue using banned flavors (statistically significant for non-TM flavors but not for menthol). Those primarily using non-TM flavors before the ban were most likely to quit using e-cigarettes and more likely to continue the same flavor afterward.
The inhalation of harmful chemicals can cause irreversible lung damage and lung diseases. This study examined the impact on adult e-cigarette users from the recent e-cigarette-only flavor bans in Washington State, New Jersey, and New York. We found that most respondents continued to use e-cigarettes with banned flavors post-ban and obtain banned-flavor e-cigarettes through legal channels. Enforcing compliance of retailers to the policy is crucial to control e-cigarette use. First, we depicted the characteristics of respondents from the three states with chi-square tests to evaluate demographic differences by state and the distribution of respondents by their tobacco and nicotine use status.
There is an urgent, overdue need for standardized processes for the disposal of e-cigarette devices, refills and e-liquids. Waste management and hazardous waste disposal plants are not currently equipped to handle e-cigarette waste and federal regulations still have not caught up to the need for guidance on disposal of these types of small electronics containing toxic waste. Federal, state, and/or local governments need to set clear standards on environmentally responsible e-cigarette waste disposal and hold the industry accountable for adhering to them. E-cigarettes not only pose substantial health risks to youth and young adults, they pose a significant environmental threat (see the Truth Initiative fact sheet on Tobacco and the Environment).
Analyses from the Population Assessment for Tobacco and Health study show that the leading reason for youth and young adult e-cigarette use is “they come in flavors I like” — with 77.9% and 90.3% selecting this as a reason, respectively. In comparison, only 66.4% of adults aged 25 and over selected this as a reason. Preliminary data published in Nicotine & Tobacco Research showed that after just two weeks of using This is Quitting, more than half of participants — 60.8% — reported that they had reduced or stopped using e-cigarettes. In our fight to end smoking, vaping and nicotine addiction, we focus on the issues that matter most. We constantly monitor the latest topics and trends in tobacco and substance use.
Use of electronic cigarettes (e-cigarettes) impairs indoor air quality and increases FeNO levels of e-cigarette consumers. E-cigarette manufacturers are using marketing tactics used by the tobacco industry to lure kids to conventional cigarettes. Their tactics include slick magazine ads, sponsorship of concerts and auto races, celebrity endorsements and sweet, colorful flavors.21 In addition, e-cigarettes are often aggressively placed in convenience stores near candy.
The rise of e-cigarettes and vaping has raised concerns that another generation may become dependent on nicotine. Whether you want to build skills, practice quitting for a few days, or get support to quit for good, we have a text messaging program that can help. The combination of medication and support is known to increase the chance of quitting for good. Support PAVeHelp us protect our kids from the dangers of vaping and tobacco use and the predatory behavior of the tobacco industry. More than 11% of young adults ages used e-cigarettes, the highest among all adults.
However, e-cigarettes containing 20 mg/mL of nicotine are more equivalent to normal cigarettes, based on the delivery of approximately 1 mg of nicotine every 5 min [40]. ESD aerosol is a new source of pollution and toxins being emitted into the environment. We do not know the long-term health effects of ESD use and although the industry marketing of the product implies that these products are harmless, the aerosol that ESD emit is not purely water vapor. In conclusion, we sought to replicate the potential effects of exposure of the user in an acute in vitro system using our vaping-condensate technique.
A 2021 review found people who used e-cigarettes to quit smoking, as well as having expert face-to-face support, can be up to twice as likely to succeed as people who used other nicotine replacement products, such as patches or gum. E-cigarettes are devices that heat a liquid, called e-liquid, into an aerosol that the user can inhale. Although e-liquids do not contain tobacco, they contain chemicals, usually including flavorings, and often contain nicotine, which is addictive. E-cigarettes are tobacco products that come in many shapes and sizes. Others have a modern, sleek design and look like writing pens, highlighters, USB sticks, or other everyday items. Larger devices such as tank systems, or “mods”, do not look like other tobacco products.
As I said, it’s in the company’s best interest if they’ve done a randomized controlled trial or they’ve done the right kind of cohort study to submit that kind of data to us. So one of the ways that an application can fail is at a stage before we even get to scientific review—when there isn’t enough of the necessary information about the product for us to be able to conduct a review. We have rejected applications for millions of products on that basis. Companies must now submit an application to FDA to keep selling existing e-cigarette products or to sell new e-cigarette products. Researchers identified vitamin E acetate as the main cause of illness.
Compared with heterosexual individuals, persons who identified as bisexual had a higher prevalence of current e-cigarette use (12.2% [95% CI, 11.0%-13.7%] vs 6.8% [95% CI, 6.6%-7.1%]) and daily e-cigarette use (6.5% [95% CI, 5.4%-7.8%] vs 3.2% [95% CI, 3.0%-3.3%]). We summarized participant sociodemographics and chronic health conditions using proportions for the entire sample and for those reporting current and daily e-cigarette use. We calculated the age-standardized prevalence of current and daily e-cigarette use overall, within subgroups including combustible cigarette use categories (never, former, or current), and across age groups. Household income level was based on the 2021 federal poverty line.20 Weight and height were self-reported; body mass index was calculated as weight in kilograms divided by height in meters squared.
On this webpage, these products are collectively referred to as e-cigarettes. The long-term health effects of e-cigarettes are not well understood yet. But the science clearly indicates vaping is not a safe or healthy alternative to smoking. We’ll continue to support research into the health consequences of this and other tobacco product trends that aim to appeal to a new generation of users. New York State has enacted strong policies to protect youth from accessing tobacco products and denormalize tobacco and nicotine use to prevent lifelong addiction, illness, and early death. Policies include banning the sale of flavored vapor products, ending price discounts on tobacco and vapor products, and banning the exterior display of tobacco and vapor product ads near schools.
It now appears that e-cigarettes may present their own unique health risks, including to the respiratory and cardiovascular systems. Given the products’ relatively recent introduction to the marketplace, further research is needed to evaluate the short and long term health impacts of e-cigarettes. The harms of e-cigarette use in young people include not only the deleterious effects of nicotine, but also exposure of the lungs and airways to potentially toxic solvents and flavoring chemicals.
It may also increase the risk of developing mood disorders and problems with impulse control. In young people, the use of nicotine can impact the reward system in the brain. In time, this can make the use of other drugs, such as cocaine, more pleasurable, according to the National Institute on Drug Abuse (NIDA). Flavors vary widely, from “traditional” and menthol to watermelon and “lava flow.” Some e-cigarettes taste like traditional cigarettes and even mimic the tastes of specific brands.
Whilst long-term health effects are not fully known, we do know that they generate toxic substances, some of which are known to cause cancer and some that increase the risk of heart and lung disorders. Electronic delivery systems have also been linked to a number of physical injuries, including burns from explosions or malfunctions, when the products are not of the expected standard or are tampered with by users. The use of e-cigarettes is unsafe for kids, teens, and young adults.
Linking to a non-federal website does not constitute an endorsement by ODPHP or any of its employees of the sponsors or the information and products presented on the website. Talk to your children’s pediatrician, who may be able to provide treatment or make a referral, if you are concerned that your child is vaping and/or addicted to vaping. As an example, NIDA point to the practice of “dripping.” This involves inhaling solutions dripped directly onto the heater coil “to produce a stronger throat hit.” The specific risks of these practices are still unclear. Experimenting with different ways of using vaping materials may be additionally risky. A website along with social media resources for teens to give them the facts about vaping and help them not become a tool. Primary spontaneous pneumothorax, or collapsed lung, occurs when there’s a hole in the lung through which oxygen escapes.
In her free time, she likes to ski and watch her son’s hockey games. We also need to determine what types of marketing claims will encourage more people who smoke to consider switching entirely to MRTPs. Provisions to speed up the MRTP authorization process could be considered to increase the number of applications from e-cigarette brands, with an emphasis on menthol-flavored e-cigarettes. This would rapidly expand access to lower-risk e-cigarette options and address health disparities from menthol cigarette use.
One study detected vitamin E acetate in the lung fluid of 48 out of 51 EVALI patients sampled across 16 states. By contrast, lung fluid samples taken from healthy people did not contain the vitamin. E-cigarettes, Vapes and JUULs – What Schools Should Know Information on e-cigarettes, “vapes” and JUULs for schools to learn more about what they are, why kids use them and health risks.
Even if you have used tobacco yourself, your children will listen if you discuss your struggles with nicotine addiction. Be clear that you don’t approve of them smoking or using e-cigarettes, and that you expect them to live tobacco-free. Today, more high school students use e-cigarettes than regular cigarettes. The use of e-cigarettes is higher among high school students than adults.
Similarly, the 2018 National Academies (NASEM) report found limited evidence on the effectiveness of e-cigarettes to promote quitting. Among adult users, this is a troubling pattern because it suggests that some e-cigarette use may be supplementing smoking instead of replacing it. Because there is no safe level of smoking, there are concerns that this behavior suppresses efforts to completely quit smoking (i.e., people choosing to “cut down” instead of quitting smoking entirely). Some individuals using e-cigarettes to quit may experience a period of dual use as they transition between products, complicating the issue. The terms “e-cigarettes” and “e-cigs” are often used for electronic cigarettes, as well as for e-pens, e-pipes, e-hookah, and e-cigars.
Then there are other pouches that contain synthetically made nicotine, which is made in the lab and is not derived from tobacco. I don’t know if it’s always apparent from the label whether it’s synthetic or not, but that’s a nuance that we’ve seen in our research. This trend was exacerbated by aggressive marketing lost vape ursa nano, which often targeted younger audiences with social media campaigns and appealing flavors, leading to widespread use among teens throughout the decade.
The concentration of nicotine in liquid products is higher than most other tobacco products. With millions of teens and young adults using e-cigarettes, a new generation could become addicted to nicotine and face other health risks. For some adult smokers, e-cigarettes may offer a less harmful substitute for traditional cigarettes. However, long-term effects on users, second-hand exposure, and environmental effects are not yet fully known.
They are also touted by some users as a “safer” alternative to smoking, and as a way to either quit smoking cigarettes, or to smoke in places where cigarette smoking is not allowed. However, no rigorous scientific studies have shown that they are safe for use. According to a 2019 CDC industry update, one out of every 10 high school students reported using tobacco products, due in part to easy access through mail deliveries and online sellers.
It should be noted that there are seven FDA-approved quit aids that are proven safe and can be effective when used as directed. To date, no e-cigarette has been approved as a cessation device or authorized to make a modified risk claim, and more research is needed to understand the potential risks and benefits these products may offer adults who use tobacco products. The mid-to-long-term consequences of e-cigarettes are not yet known, as it’s a new product and has been sold for less than a decade in the U.S. While much remains to be determined about these lasting health consequences of these products, we are very troubled by what we see so far.
We want to make a difference in the lives of our users, and create products that can fit all levels and styles of vapers, to help as many as possible. From sharing our profits with our employees to using 100% renewable energy to taking on the big boys – frombig tobacco to big pharma – we’re determined to make a positive impact on the world. You can join us – on ourblog you can learn how to be an environmentally friendly vaperor find out who is trying to protect cigarettesfrom vaping for their own ends.
Small and sleek, these products can look a lot like a computer flash drive or pen. This makes it tricky for adults to recognize them right away as vaping tools. Pod-based e-cigarette devices are easy to hide in a fist or a pocket. The CDC’s Office on Smoking and Health (OSH) developed this presentation to educate youth on e-cigarettes, including the health risks, the factors that lead to e-cigarette use, and what youth can do to avoid all tobacco products, including e-cigarettes.
Vapes can also be used with marijuana or tetrahydrocannabinol (THC). New ‘pod-mod’ style vape products are similar in shape and size to JUUL® and other vape sticks but are disposable. It is generally accepted that e-cigarettes produce fewer of the toxins found in cigarette smoke. However, it is becoming increasingly apparent that this frame is not adequate to tell the entire story regarding individual health impacts.
The age-standardized prevalence of current and daily e-cigarette use was 6.9% (95% CI, 6.7%-7.1%; weighted sample approximately 15 million) and 3.2% (95% CI, 3.1%-3.4%; weighted sample approximately 7 million), respectively (Table 2). Among individuals who reported current e-cigarette use, the proportion of daily use, as a measure of established use and possible nicotine addiction, was 46.6% (95% CI, 45.3%-48.0%) (Table 2 and eTable 1 in Supplement 1). Many themes in e-cigarette marketing, including sexual content and customer satisfaction, are parallel to themes and techniques that the tobacco industry aimed at youth and young adults in their advertising and promotion of conventional cigarettes. Flavored e-cigarettes are very popular among youth and young adults.
Many vapes don’t state they contain nicotine, even though they do, and often at high strengths. Some of the research for Tobacco Tactics was funded by Cancer Research UK Limited and Bloomberg Philanthropies. This work has previously received funding from The New Venture Fund, Smokefree South West, and the Economic and Social Research Council (ESRC) Knowledge Exchange Opportunities scheme. These funders have had no input into the research reported on this website or its conclusions. They are not responsible for its content or publication, nor do they necessarily endorse it. However, placement in an alternative school setting can lead to more severe outcomes, what many experts refer to as a school-to-prison pipeline.
The review, commissioned by PHE and led by Professor Ann McNeill (King’s College London) and Professor Peter Hajek (Queen Mary University of London), suggests that e-cigarettes may be contributing to falling smoking rates among adults and young people. Following the review PHE has published a paper on the implications of the evidence for policy and practice. After conducting a study published in 2021, researchers said they were surprised to find that vaping marijuana was even worse than using e-cigarettes.
Because of this and other studies, vitamin E acetate is considered the main cause of EVALI. Other chemicals found in nicotine- and THC-containing vaping products may also play a role in the condition. Below are answers to common questions about e-cigarettes, including health consequences, risks of secondhand emissions, kids and e-cigarettes and FDA oversight. Respondents reported several features of their e-cigarette use for the past 30 days (for post-ban) and in the month before the state flavor ban (for pre-ban).
As 63% of participants in the EC arm still used their products at 6 months, further studies are needed to assess whether such use is beneficial or harmful. E-cigarettes produce an aerosol by heating a liquid that usually contains nicotine, flavorings, and other chemicals that make the aerosols. The liquid is sometimes called e-juice, e-liquid, vape juice, or vape liquid. Bystanders can also breathe in this aerosol when the user exhales it into the air.
Vitamin E acetate is a thickening agent often used in THC vaping products, and it was found in all lung fluid samples of EVALI patients examined by the CDC. To understand tobacco use patterns, we analyzed the prevalence of combustible cigarette use among those reporting current and daily e-cigarette use. In addition, we explored different patterns of current e-cigarette and combustible use, including sole e-cigarette use, dual use, and exclusive combustible cigarette use.
Well, if they have, it’s not public because that’s not a public process. But one can look around and see that no e-cigarettes have been approved for use as safe and effective cessation aids. Ultimately, the legal burden is on the companies to demonstrate that the benefit to adults is going to outweigh the harm to kids.
Instead, alarming evidence on adverse population health effects is mounting. If you think ENDS or other tobacco products are being sold to people who are underage, or you see another potential violation of the FD&C Act or FDA’s tobacco regulations, please report the potential tobacco product violation. Learn about public education efforts and resources that have been created to reach youth who are at higher risk of or more vulnerable to cigarette use and nicotine addiction. FDA created a toolkit, Resources for Professionals About Vaping & E-Cigarettes, for adults and professionals who work with youth. This FREE resource provides fast facts about youth vaping and e-cigarettes. Researchers have linked vitamin E acetate, a synthetic form of vitamin E found in some THC-containing vaping products, to EVALI.
You may have heard the benefits of vaping are that it’s safe or that it helps you quit smoking. Some people vape because they think it’ll help them quit smoking if they’ve already tried other methods and haven’t been able to quit. Unfortunately, you may end up addicted to vaping instead, so the benefits of vaping for smoking cessation may not be as good as they seem. Vaping is when you use a small, handheld device (like e-cigarettes, vape pens or mods) to inhale a mist of nicotine and flavoring (e-liquid). It’s similar to smoking a cigarette, but vaping heats tiny particles out of a liquid rather than burning tobacco. E-cigarettes as consumer products have not been proven to be effective for cessation at the population level.
When it comes to the question of whether it’s safer to vape or smoke, it’s a matter of degrees of danger. The FDA hasn’t regulated vaping cartridges as tightly as other products. Ingredient lists don’t always disclose everything in the product, so you don’t always know what’s in vaping fluids.
According to the 2021 National Youth Tobacco Survey, more than 2 million U.S. middle and high school students reported using e-cigarettes in 2021, with more than 8 in 10 of those youth using flavored e-cigarettes. Although they’ve been promoted as an aid to help you quit smoking, e-cigarettes have not received Food and Drug Administration approval as smoking cessation devices. A recent study found that most people who intended to use e-cigarettes to kick the nicotine habit ended up continuing to use traditional and e-cigarettes. Conclusion and Relevance These findings suggest that e-cigarette use remained common during the COVID-19 pandemic, particularly among young adults aged 18 to 24 years (18.3% prevalence). Notably, 71.5% of individuals aged 18 to 20 years who reported current e-cigarette use had never used combustible cigarettes.
E-cigarette vapour has been reported to contain up to 7×1011 free radicals per puff.10 Both nicotine-free and nicotine-containing condensate induced a significant increase in ROS release from our AMs, which may explain the induction of apoptosis in nicotine-free liquid. There was significantly greater ROS production in AMs treated with nicotine-containing condensate than in nicotine-free condensate, once again suggesting both nicotine dependent and independent mechanisms at work. The effects of ECVC with and without were ameliorated by NAC and PI3K inhibition. A Foundation-led study presented at the 2024 Society for Research on Nicotine and Tobacco annual meeting found that monthly e-cigarette sales in California declined by 41% after statewide restrictions on the sale of flavored tobacco products took effect. However, the report also noted that the tobacco industry continues to market products to offset these declines, including non-menthol cigarettes that contain other cooling chemicals.
AMs from eight never smokers, five men and three women, with normal spirometry and no history of asthma/COPD were obtained by repeated saline lavage from non-affected lung resection specimens (see online supplement for full extraction methods). This is in contrast to passive smoking (secondhand smoke), which is known to be very harmful to health. But if you find using an e-cigarette helpful for quitting and staying smoke-free, it’s much safer for you and your baby than continuing to smoke. It’s also important to choose the right strength of nicotine in your e-liquid, which will depend on how much you smoke. You can get advice on models and e-liquids from a specialist vape shop.
In 2018, the rapid rise of tobacco products led the U.S. surgeon general to issue an advisory about the youth e-cigarette “epidemic.” In 2019, youth e-cigarette use increased to even higher levels. While the most recent studies show a decrease in youth use in 2020, the rate is still alarmingly high with nearly one in five high school students reporting current e-cigarette use. In May 2021, the China Health Commission (equivalent to Ministry of Health) published China’s Report on the Health Hazards of Smoking 2020,26 which concluded that EC use is unsafe.
Never smoke indoors, in your car, or in places where children spend time. Disposable e-cigarettes are not covered by the flavor restrictions imposed by the Food and Drug Administration. In 2021 “other” flavored devices made up 71 percent of all disposable devices sold or given away, with the most-popular subcategories being fruit-flavored and fruit & menthol/mint flavored products. These two subcategories alone made up more than half of all disposable e-cigarette devices sold or given away in 2021. HB1540, sponsored in the House by Rep. Camille Lilly and in the Senate by Sen. Julie Morrison, adds electronic smoking devices to the list of items prohibited for public indoor use under the Smoke Free Illinois Act, the indoor smoking ban that was enacted in 2008.
The ingredients, including nicotine levels, vary between brands and flavors, but many products are not thoroughly or accurately labeled. From introducing appealing flavors to offering college scholarships, manufacturers and sellers of e-cigarettes aggressively target young people. There are few federal restrictions on e-cigarette marketing, allowing companies to promote their products through traditional outlets — such as TV and radio — despite a ban in 1971 on cigarette advertising in both outlets to reduce cigarette marketing to children. E-cigarette companies also take advantage of other marketing outlets, including the internet, retail environments, and recreational venues and events. Nicotine is an addictive substance, but its level of addictiveness can vary substantially depending on its mode of delivery. Nicotine delivered by the combustion of tobacco is the most addictive form.12 The rise in popularity of e-cigarettes that can deliver levels of nicotine similar to combustible cigarettes is causing concern about the potential risk for addiction.
Unsurprisingly, the FDA has only granted authorization to 4 big tobacco companies, while rejecting the millions of devices and liquids submitted by the vape industry. This includes our brand Custom Clouds and every other brand on our shelves. The Electronic Cigarette Company is one of the original online vape stores in the UK, founded in 2008.
Cig-a-likes may also contain low levels of cadmium, a toxic metal also found in cigarette smoke that can cause breathing problems and disease.11 More research is needed on the health consequences of repeated exposure to these chemicals. There are also reports of lung illnesses and deaths related to inhalation of certain vaping oils into the lungs, which have no way to filter out toxic ingredients. As the menthol ban hangs in limbo, people who cannot quit smoking those products altogether could be advised to shift to less harmful alternatives. These so-called modified risk tobacco products (MRTPs) are less dangerous than traditional cigarettes, according to the Food and Drug Administration (FDA). But they have generated limited sales, in part because they use ineffective advertising and must undergo an onerous authorization process.
Among people who were hospitalized with severe EVALI, most were younger than 35 and used THC-containing vapes from informal sources (online, family or friends). However, EVALI can happen in anyone using either nicotine or THC-containing vapes. The particles you inhale while vaping can cause inflammation (swelling) and irritation in your lungs. This can lead to lung damage like scarring and narrowing of the tubes that bring air in and out of your lungs. Researchers don’t yet know all the effects vaping can have on your body. Nicotine exposure in pregnant women can adversely affect the development of the fetus.
At sub-cytotoxic levels both ECVC and nfECVC inhibited phagocytosis of E. Aureus, suggesting vaping might significantly impair bacterial clearance. Our data are supported by murine models in which mice exposed to e-cigarette vapour showed significantly impaired pulmonary bacterial clearance compared with air-exposed mice following an intranasal infection with Streptococcus pneumoniae. In vitro PAFR is significantly upregulated by inducers of oxidative stress such as traditional cigarette smoke. E-Cigarettes, also called personal vaporizers or “vapes”, present another way for smokers to ingest nicotine. E-Cigarettes have been marketed to young adults and adolescents through the use of candy and fruit flavors.
That could be because that group is more likely to use e-cigarettes continuously throughout the day, therefore getting more nicotine into their systems. As a parent or caregiver, you have an important role in protecting children from e-cigarettes. Set firm expectations that they do not use any type of commercial tobacco product, including e-cigarettes and vapes. For more guidance, here’s a tip sheet for talking to your children about e-cigarettes. “[B]efore marketing tobacco products for reduced risk, companies must demonstrate with scientific evidence that their specific product does in fact pose less risk or is less harmful,” the FDA said in a statement.
In response to this issue, the PACT Act Amendment prohibits sellers from using the U.S. Post Office to ship e-cigarettes, vapes, flavored and smokeless tobacco products. The PACT Act applies to all shipments in interstate commerce (15 U.S.C. § 376) as well as to all delivery sales. While e-cigarettes are often marketed as a way for adults to quit nicotine, a whole new generation of non-smokers is now taking to the habit in young adulthood.
Endothelial cell migration is an important mechanism of vascular repair than can be disrupted in smokers due to endothelial dysfunction [25, 26]. The decision to pursue a smoking cessation objective, even in such a controlled form, should be made only after considering national circumstances, along with the risk of uptake and after exhausting other proven cessation strategies. While the Family Smoking Prevention and Tobacco Control Act of 2009 prohibited the sale of most flavored cigarettes, the flavor ban did not extend to menthol flavored cigarettes or to any flavored non-cigarette tobacco products such as cigars, hookahs, and e-cigarettes.
Drugwatch.com’s trusted legal partners support the organization’s mission to keep people safe from dangerous drugs and medical devices. Vaping may be safer than smoking for adults past their mid-20s who already smoke. But e-cigarettes are not safe for nonsmokers, teens, young adults or pregnant women, according to the CDC. However, the next day, Juul filed an emergency appeal that allowed it to continue selling its products until the FDA finishes a second review of safety data. In September 2022, the e-cigarette maker sued the FDA for refusing to disclose documents that led to the ban. The term “vaping” comes from the act of inhaling and exhaling e-cigarette vapor (which is actually an aerosol).
The study led by Dr. Vindhyal included data from a total of 96,467 respondents from the National Health Interview Survey, a Centers for Disease Control and Prevention-fielded survey of Americans, from 2014, 2016 and 2017. In their analyses, researchers looked at the rates of high blood pressure, heart attack ijoy venta, stroke, coronary artery disease, diabetes and depression/anxiety among those who reported using e-cigarettes (either some days or daily) and nonusers. Those who reported using e-cigarettes were younger than nonusers (33 years of age on average vs. 40.4 years old), according to the ACC release. Statewide, Alaskans must be 19 to legally purchase tobacco products and electronic cigarettes. The legal age to purchase tobacco products is 21 in the cities of Anchorage and Sitka. For more information, about e-cigarette use in Alaska, visit the Alaska Department of Health.
E-cigarettes are battery-powered devices that generate an inhalable aerosol that usually contains nicotine. With a 399.73% increase in retail e-cigarette sales (excluding internet sales and tobacco-specialty stores) from 2015 through 2020, the environmental consequences of e-cigarette waste are enormous. Dr. Baldassarri says that e-cigarettes do help some people quit smoking, which is a good thing, but points out that there is no long-term data on the safety of e-cigarette use itself.
These products are also sometimes called “JUULs” (after a branded e-cigarette of the same name), “vapes,” and “vape pens.” Governor Gretchen Whitmer has taken aggressive action to protect Michigan kids from the harmful effects of vaping, including making Michigan the first state in the nation to ban flavored nicotine vaping products. To protect kids now, states and cities must also continue their growing efforts to end the sale of flavored e-cigarettes, as well as other flavored tobacco products.
Their pod designs are also exceptional, with the XLIM V3 Pod capable of being refilled without removal from the battery unit. Innokin kits deliver consistent flavour and vapour production and feature simple interfaces, aspects that make a beginner vaper settle comfortably into a new means of nicotine intake. While they started with more sub-ohm kits and tanks such as the iSub VE, it was low-powered MTL vape devices that began to draw vapers in due to their reliability and simple use functions.
Design, Setting, and Participants This cross-sectional study used data from the 2021 Behavioral Risk Factor Surveillance System (BRFSS) database. The BRFSS is the largest national telephone-based survey of randomly sampled adults in the US. Adults aged 18 years or older, residing in 49 US states (all except Florida), the District of Columbia, and 3 US territories (Guam, Puerto Rico, and the US Virgin Islands), were included in the data set. Nicotine can harm brains as they develop—which continues until age 25 or older!
Extended EC use may be beneficial for some previous smokers by helping them to maintain some of the subjective rewards of smoking, avoid postcessation weight gain, or prevent relapse. However, although EC use is expected to pose few health risks of smoking, some adverse health outcomes of long-term EC use are likely.25,26 Varenicline is not used long term and so has an advantage in this respect. Participants were included if they smoked at least 10 cigarettes per day for at least 5 years, had expired air carbon monoxide (CO) reading of 9 parts per million (ppm) or greater, were age 25 to 45 years, and were motivated to stop smoking. Instead of bathing lung tissue with a therapeutic mist, just as a nebulizer does, vaping coats lungs with potentially harmful chemicals. E-liquid concoctions usually include some mix of flavorings, aromatic additives and nicotine or THC (the chemical in marijuana that causes psychological effects), dissolved in an oily liquid base. “We think that some of the vaporized elements of the oil are getting deep down into the lungs and causing an inflammatory response,” explains Broderick.
One of the most popular e-cigarettes is Juul, but hundreds of different e-cigarette brands are currently available to consumers. In June 2022, the FDA banned Juul from selling it’s products after finding the company provided “insufficient and conflicting data” on risks. In light of this spike in youth e-cigarette use, along with the recent U.S. outbreak linked to more than 2,000 lung illnesses and over 40 deaths, the AMA has called for a total ban on all e-cigarette and vaping products that do not meet FDA approval as cessation tools.
E-cigarettes, aka JUULs and vape pens, use a battery to heat up a special liquid into an aerosol that users inhale. The “e-juice” that fills the cartridges usually contains nicotine (which is extracted from tobacco), propylene glycol, flavorings and other chemicals. Studies have found that even e-cigarettes claiming to be nicotine-free contain trace amounts of nicotine. Additionally, when the e-liquid heats up, more toxic chemicals are formed. In 2016, the FDA established a rule for e-cigarettes and their liquid solutions.
The agency said it would ban all e-cigarette flavors except tobacco, mint and menthol in retail stores. Fruity or sweet e-cig flavors can now only be purchased through age-restricted stores or online merchants that can verify a buyer’s age. A 2018 report from Truth Initiative, an anti-smoking group, found that 15- to 17-year-olds were 16 times more likely to have used a Juul e-cig than older age groups.
Electronic cigarettes produce an aerosol by heating a liquid that usually contains nicotine, flavorings and other chemicals. Several states have imposed restrictions on the sale of e-cigarettes. There are also restrictions on liquids with flavors that may be more attractive to younger people. When the user sucks on the mouthpiece, the heating element vaporizes the solution, which the person then “vapes ijoy vape uruguay,” or inhales.
They also reported increased likelihood in trying e-cigarettes and decreased quit success when compared to cigarettes. For a summary of Iowa youth vaping/e-cigarette use statistics from the 2018 IYS, check out our infographic and factsheet. Quitting is your best option to reduce your risk from smoking and tobacco use-related diseases. E-cigarettes and vape products are not FDA-approved cessation devices.
This conclusion was widely reported by Chinese media during the next year or so and discussed repeatedly at the WeChat forum, and we estimate that it led some 20% of participants in the EC arm to stop EC use. As a result, we estimate that some 15% of participants in the varenicline arm stopped using their product. These events may have reduced quit rates in the EC and varenicline arms, but this would dilute rather than amplify the difference between these 2 arms and the NRT arm. Another external event affecting the trial was the COVID-19 pandemic.
The chemical is not only highly addictive, but it can increase blood pressure and affect the flow of blood to the heart. It may also harden the arterial walls, which can lead to a heart attack. The FDA Commissioner released a statement regarding new enforcement actions and a plan to prevent youth e-cigarette use, specifically calling out JUUL, in August, 2018 and an additional statement in November 2018 with plans to limit access to flavored tobacco products.
E-cigarette use was higher among older students, with one in 11 (9%) seventh grade students reporting use, compared to one in 38 (2.6%) in sixth grade. As with high school students, e-cigarette use was much more common than cigarette use. The Texas Tobacco Quitline offers free, confidential, and convenient cessation services to Texas residents ages 13 and older. This includes quit coaching, up to 2 weeks of nicotine replacement therapy, and a youth digital program for those ages 13-17. The AHA supports maintaining the Food and Drug Administration’s regulatory authority over e-cigarettes along with other tobacco products. Some e-cigarette brands and other nicotine products state they contain synthetic nicotine rather than nicotine made from or derived from tobacco.
A P-value ≤0.05 was considered to represent a statistically significant difference. You can buy them from specialist vape shops, some pharmacies and other retailers, or on the internet. As with all rechargeable electrical devices, the correct charger should be used and the device should not be left charging unattended or overnight. There have been instances of e-cigarettes exploding or catching fire. EBook files are now available for a large number of reports on the NAP.edu website.
Objective To evaluate whether ECs are superior to NRT and noninferior to varenicline in helping smokers quit. Learn more about e-cigarette aerosol from the Centers for Disease Control and Prevention. According to both the Center for Disease Control and Prevention and the United States Surgeon General, e-cigarette use among young people is unsafe.
Nicotine exposure damages adolescent brain development (learning, attention, impulse control), which does not end until one’s mid-20s. It also contributes to the hardening of the arterial walls, which in turn, may lead to a cardiac event. The aerosol, or “vapor,” produced by e-cigarettes is not a harmless, flavorful water vapor.
They appeared on the U.S. market in 2015 and are now the top-selling brand of e-cigarette in the country. You have an important part to play when it comes to talking to kids about the harms of e-cigarettes. Although secondhand vapor may not affect the lungs the same way as vaping, it is better to avoid it, if possible.
This article looks at the potential harms of vaping marijuana, how to identify them, and how vaping marijuana compares to vaping nicotine. The current study leaves many questions unanswered, but it joins a wave of concern over e-cigarette use among teens, which the US surgeon general described in 2018 as an epidemic. Very little research has evaluated the potential of metal exposure from vaping or the effect of certain flavors ijoy vapes online, making the long-term outcomes an even bigger mystery. Teenagers who regularly puff away on their vape throughout the day could be exposing their bodies to potentially toxic metals. Vaping worked in a month, and she’s been off cigarettes for more than two years. “I’m breathing, sleeping, and eating much better since I started vaping. My ‘smoker’s laugh’ went away, and I no longer smell like an ashtray.”
According to the 2023 National Youth Tobacco Survey, 2.1 million teens currently vape. Among those, more than 50% said they commonly use Elf Bar vape products and more than 20% said they often use Esco Bar e-cigarettes. These disposible vape pens account for nearly 1.5 million teen users across the country. “By banning the sale of certain tobacco products that have pervaded youth culture, we can make it harder for children to access these dangerous products,” Supervisor Lynda Hopkins, vice chair of the Board of Supervisors, said. A new state law last year requires vape shops to get licenses from local jurisdictions, as retailers selling cigarettes and other tobacco products must do. FAU’s Charles E. Schmidt College of Medicine is one of approximately 157 accredited medical schools in the U.S.
They contain nicotine, propylene glycol, glycerin, flavorings, and potentially dangerous chemicals like formaldehyde and various metals. Products containing nicotine or tobacco can’t be legally sold to people under age 21, but the government has faced challenges in regulating sales of disposable, imported devices. Some 10% of high school students said last year they had used e-cigarettes in the previous month, down from 14% the previous year, according to a national survey. About 5% of middle school students said they recently used e-cigarettes. During the ban, the city will study stores that sell vaping products, seek public input, look at what other communities have done and consider zoning changes, said Doug Plowman, planning director.
It was not until months later that I understood, at which point my son had now been vaping every day for 3 months, 4 to 5 times a day. LEXINGTON, Ky. — Governor Andy Beshear, Ky-D, signed House Bill 11 into law in early April. It’s a bill that bans retailers from selling unauthorized vapor products. The wording of the bill has vape store owners concerned, and a lawsuit was filed shortly after it was passed to address this. But now that I’ve gotten rid of the endless, all-day vaping, and a nicotine hit makes me stink like a dive bar ashtray, makes my mouth taste like dirt, and makes my friends recoil from my presence, I’ve got reasons to cut back.
International regulation of e-cigarettes varies widely, and, due to the relatively recent introduction of the product category, is rapidly changing. Teens and young adults can text “DITCHVAPE” to and get immediate help. Home to an array of public health programs, initiatives and interventions aimed at improving the health and well-being of women, infants, families and communities. The continuum is inclusive of primary, secondary, and tertiary prevention activities. “The nicotine in e-cigarettes causes irregular heartbeats (arrhythmias) in a dose-dependent manner by stimulating the very receptor that many heart medications are designed to inhibit,” Carll said. Due to concerns about adverse events being more likely in older age groups, the sample was limited to adults aged 25 to 45 years.
Jacob eventually tried vaping THC as well, but ultimately continued with flavored nicotine because of the flavors; cherry was one of his favorites. He said it tasted great and he could easily hide it from me, or any other adult, by simply passing it off as candy should someone ask about the odor. While many of the products that are sold at 723 Vapor will likely be banned in January, Florence hopes that the lawsuit will help with fixing some of the wording to be able to continue selling hemp vape products. On the rare occasions I partake, instead of filling my nostrils with the taste of a warm crème brûlée, my mouth tastes like a street gutter for an hour. I like the nicotine, but everything else about the experience is viscerally revolting.
Jacob, who was a starter player on varsity and who usually played the entire game, with a break only during half time, was now having problems getting through a whole game. As a matter of fact, he has breathing issues with simple things like gym class or even a friendly community basketball game. We are hoping that over time his breathing will rectify itself, and like the addiction, will just be a bad memory. He was a 17-year-old honor roll student in the 11th grade, taking AP and Honors classes.
Protect their health and their future by equipping yourself with information for this important conversation. In January 2020, the FDA prioritized enforcement against the sale of most candy or fruit flavors in “closed pod” refillable e-cigarettes, like the popular brand JUUL, but exempted disposable flavored e-cigarettes including newer products like Puff Bar. The e-cigarette industry has responded by offering newer products that aren’t covered by existing enforcement guidelines. In July 2020, the FDA issued warnings to e-cigarette retailers and manufacturers, including Puff Bar lost vape orion bar, to remove their flavored disposable e-cigarettes and youth appealing e-liquid products from the market. In young people, the amount of nicotine needed to establish an addiction has been estimated at around 5 mg a day, or roughly one-quarter of an e-cigarette pod.
Participants received a 12-week supply of varenicline (Chantix; Pfizer) and a leaflet with product use instructions. Participants were instructed to start using varenicline from the next day and stop smoking completely from their TQD onward. Participants were then randomized into 1 of the 3 interventions and given their study product and instructions on how to use it.
Unlike traditional cigarettes, e-cigarettes are made up of a battery-operated heating part — a cartridge (unit) that typically holds nicotine and other chemicals that change into a chemical-filled aerosol when heated. As a result of the FDA’s missed deadlines and inadequate enforcement, flavored e-cigarettes remain widely available online and in stores across the country. Every day flavored e-cigarettes remain on the market, our kids remain at risk. The FDA must act without further delay to remove all flavored e-cigarettes from the market. Despite not authorizing a single synthetic nicotine product, it has allowed these products – including e-cigarettes in kid-friendly flavors – to stay on the market well past the July 13 deadline.
The sale of tobacco products to minors is prohibited by law.This is an age restricted product and age verification is required at sale. Disturbances in AM function could therefore increase the risk of infection and enhance susceptibility to chronic obstructive pulmonary disease (COPD). We also assessed the effects of our ECVC with and without nicotine on human AMs to determine if this is a key component and determine whether anti-oxidants abrogate any of the effects. Objective Vaping may increase the cytotoxic effects of e-cigarette liquid (ECL). We compared the effect of unvaped ECL to e-cigarette vapour condensate (ECVC) on alveolar macrophage (AM) function.
And finally, the exposure to point-of-sale marketing of e-cigarette has also been identified to affect the smoking cessation success [96]. Is there sufficient toxicological data on all the components employed in e-liquids? Do we really know the composition of the inhaled vapour during the heating process and its impact on health?
