FAQ about e-cigarettes
Read the most frequently asked questions (FAQ) about our electronic cigarettes
What are electronic cigarettes?
Electronic cigarettes (also known as e-cigarettes or personal vaporizers) are an alternative to tobacco cigarettes. They are battery-operated devices that create a mist or vapor that is inhaled instead of smoke. The rechargeable battery powers a heating element called an "atomizer." The element uses low heat to turn liquid in the cartridge, which contains propylene glycol, glycerin, food flavoring and nicotine, into a fog-like mist.

Are e-cigarettes safe?
Do e-cigarettes contain anti-freeze?
No. This myth was created by a 2009 FDA (U.S. Food and Drug Administration) press statement regarding electronic cigarettes. The FDA tested 18 cartridges from 2 companies. Of those 18 cartridges, 1 tested positive for a non-toxic amount of diethylene glycol (approximately 1%). While diethylene glycol is occasionally used in anti-freeze, the chemical is not a standard ingredient in e-cigarette liquid and it has not been found in any other samples tested to date.
The base liquid for e-cigarette liquid is usually propylene glycol. Propylene glycol is considered GRAS (Generally Recognized As Safe) by the FDA and EPA. While it is also sometimes found in anti-freeze, it is actually added to make the anti-freeze less toxic and safer for small children and pets. Propylene glycol is a common ingredient found in many of the foods we eat, cosmetics we use and medications we take. It is also used in the fog machines used in theaters and night clubs.
Do e-cigarettes cause cancer just like tobacco cigarettes?
Though testing by the FDA and some researchers have discovered trace amounts of tobacco-specific nitrosamines, which are known to cause cancer with high exposure, the amounts found were extremely low and unlikely to cause cancer. To put it in perspective, an e-cigarette contains nearly the exact same trace levels of nitrosamines as the FDA-approved nicotine patch and about 1,300 times less nitrosamines than a Marlboro cigarette. This means that e-cigarettes would not be any more likely to cause cancer than FDA-approved nicotine gums, patches or lozenges.
What about all of the news reports that e-cigarettes contain toxic chemicals and metals?
The reports that there are studies that show potential health risks due to e-cigarette use are premature. In spite of what has been reported, the studies done to date have not only been largely inconclusive, but have actually found that the levels of contaminants detected in e-cigarette liquid and vapor are so low that it is highly doubtful they would even pose a health risk. Most certainly, they are thousands of times less of a risk than continuing to smoke. The fact is, the mere "detection" of a chemical does not mean that a product is hazardous. Every day we harmlessly consume and breathe in chemicals that would be toxic at much higher levels. It is disingenuous for public health organizations that disapprove of e-cigarettes to point to the trace levels found in e-cigarette studies as conclusive evidence of a potential health risk.
Dr. Igor Burstyn, of Drexel University, reviewed all of the available chemistry on e-cigarette vapor and liquid and found that the levels reported — even in those studies that were hyped as showing there is a danger — are well below the level that is of concern. His report was peer-reviewed and published January 2014 on Bio Med Central's Public Health Journal: "Peering through the mist: systematic review of what the chemistry of contaminants in electronic cigarettes tells us about health risks"
It is clear to anyone who reviews the more than 60 available studies on e-cigarette liquids and vapor that the benefits of e-cigarettes also "far outweigh the risks."
If there are over 60 studies of e-cigarette vapor and liquid, why do health experts say we don't know what is in them or that they may be more dangerous than traditional cigarettes?
Good question. Unfortunately, we don't have a clear answer. What we do know is that pharmaceutical companies do not like to see smokers switching to e-cigarettes instead of using pharmaceutical drugs and nicotine products. The pharmaceutical industry and its "foundations" fund a lot of anti-tobacco research and supports many of the anti-tobacco organizations and politicians that object to e-cigarettes and tobacco harm reduction policies.
We also know that there is a small, but very vocal, part of the public health community that is against anything that doesn't require 100% abstinence from all tobacco and nicotine. Their objection to e-cigarettes appear to be more ideological than science-based and it seems they would rather smokers remain uncertain enough about e-cigarette safety that they will choose to keep trying to quit smoking with traditional methods instead. Unfortunately, while this may be an option for those smokers who are actively trying to quit, it keeps smokers who aren't trying to quit - or who fail to quit using traditional methods - using the most hazardous product on the market, rather than a far safer alternative.
Can e-cigarettes help me quit smoking?
E-cigarettes are not approved to be marketed as nicotine cessation products like the nicotine gums and patches on the market. However, that doesn't mean that some smokers haven't found them an effective way to wean from nicotine. There is also a lot of real-world evidence and even some studies that strongly indicate that e-cigarettes are an effective alternative to smoking. Surveys show that up to 80% of e-cigarette users quit smoking traditional cigarettes while using e-cigarettes. One study showed e-cigarettes worked at least as well as the nicotine patch for nicotine replacement therapy.
However, while some users have gradually reduced the nicotine levels down to zero, the majority of e-cigarette users treat the devices as an alternate source of nicotine and not as a nicotine cessation program. So there is not as much scientific evidence yet that show how effective e-cigarettes are when used to treat or cure nicotine addiction. Yet, anecdotal reports by users who have used e-cigarettes as a way to wean from nicotine also indicates they seem to be very effective way to break smoking triggers and dramatically reduce nicotine levels. As with pharmaceutical NRTs, it depends upon the smoker and the strength of his or her addiction and resolve to quit. E-cigarettes also appear to be a much safer option for short-term use in the event of relapse.
The good news is, nicotine by itself has very low health risks, so switching to e-cigarettes can be nearly as good as quitting altogether. The most important thing for those who cannot or will not quit nicotine to do is to stop the exposure to the harmful chemicals in cigarette smoke and e-cigarettes can help them do it.
What is CASAA's involvement in e-cigarette research?
In late 2010, CASAA's (The Consumer Advocates for Smoke-free Alternatives Association) board of directors discussed CASAA's mission in relation to the current and future involvement in smokeless and e-cigarette research and studies and concluded that CASAA does not have the funding nor the staff to endorse, supervise and/or fund any ongoing research. At that time, the Board agreed to discontinue fundraising for research projects and instead continue to direct its efforts and funding toward the continued education of the public, media and legislators about tobacco harm reduction; provide public access to completed research and studies; and to continue the fight to keep smokeless alternatives available, effective and affordable.
To that end, CASAA forwarded any donations contributed by its members to the studies for which they were intended and voted not to do any more fundraising exclusively for research. Additionally, because CASAA has no first-hand involvement with any research or studies, we are unable to comment on the current progress, fundraising, validity or administration of any ongoing studies.
In 2013, CASAA raised funds from its members for a small grant of $15,000 to Dr. Igor Burstyn, who is an associate professor at Drexel University's Department of Environmental and Occupational Health and a researcher in the field of environmental and occupational health, with training in both epidemiology and occupational hygiene. Dr. Burstyn's paper, "Peering through the mist: systematic review of what the chemistry of contaminants in electronic cigarettes tells us about health risks" was peer-reviewed and published in Bio Med Central's Public Health Journal in January 2014. Dr. Burstyn reviewed all of the available chemistry on e-cigarette vapor and liquid and found that the levels reported — even in those studies that were hyped as showing there is a danger — are well below the level that is of concern. This is a definitive study that can be used to respond to claims that contaminants in e-cigarettes are dangerous and that there is a hazard to bystanders that calls for usage restrictions.
