Reality Faces Off Against Unfounded Fears

Compare and contrast reality with fears about electronic cigarettes voiced by people who have never seen one, never talked to anyone who used one, and never bothered to read the available studies.

The Fears - As reported in the Annals of Internal Medicine, Volume 153, Number 9, p. 607-609 (“E-Cigarettes: A Rapidly Growing Internet Phenomenon”):

We contend that the e-cigarette boom presents important public health concerns on at least 3 fronts. First, e-cigarettes may pose a risk as starter products for nonusers of tobacco. Although candy-flavored tobacco products and e-cigarettes were recently banned by the FDA in efforts to hinder marketing toward children, the posturing of e-cigarettes as “green” and “healthy” could deceptively lure adolescents. E-cigarettes also may represent a way for adolescents and adults to skirt smoke-free indoor air laws.


The Reality - As reported in Chapter 19 of the Tobacco Harm Reduction Yearbook 2010 (“Electronic cigarettes (e-cigarettes) as potential tobacco harm reduction products: Results of an online survey of e-cigarette users”):

All respondents previously smoked and 91% had attempted to stop smoking before trying ecigarettes. About half (55%) were 31-50, while 32% were >50 years old. Most (79%) of the respondents had been using e-cigarettes for <6 months and reported using them as a complete (79%) or partial (17%) replacement for, rather than in addition to (4%), cigarettes. The majority of respondents reported that their general health (91%), smoker’s cough (97%), ability to exercise (84%), and sense of smell (80%) and taste (73%) were better since using e-cigarettes and none reported that these were worse. Although people whose e-cigarette use completely replaced smoking were more likely to experience improvements in health and smoking caused symptoms, most people who substituted e-cigarettes for even some of their cigarettes experienced improvements.


Similar results were seen in two other surveys of users. J.F. Etter’s “Electronic cigarettes: a survey of users,” published in BMC Public Health reported, “Our results suggest that most people who buy these products are current and former smokers who use ecigarettes to help quit smoking, just as they would use NRT.” The median age was 37, ranging from 19 to 65 years. An unpublished survey conducted by the Consumer Advocates for Smoke-Free Alternatives Association (casaa.org) found that 50.9% of the 2,217 responders were between ages 30 and 49 years and 27.4% were older than 50 years, and 99.6% had been smokers.

Thus, reality certainly does not match the fears that e-cigarettes will be “starter products” geared towards adolescents and children. It is interesting that critics of e-cigarettes accuse manufacturers of offering flavors as a means of attracting children, but do not accuse the makers of Nicorette gum of luring children to their products via White Ice Mint, Cinnamon Surge, and Fruit Chill flavors.

Lastly, reality faces off against fear #3. E-cigarettes are not burned. Therefore they produce no smoke. Expressing fears that people will use them to “skirt smoke-free indoor air laws” is as ridiculous as fearing that children will purchase root beer as a means of defying laws against sales of alcohol to minors. Root beer isn’t an alcoholic beverage, and vapor isn’t air-polluting smoke.

Authors Yamin, Bitton, and Bates end their Annals of Internal Medicine essay with this statement: "Although the safety and efficacy of e-cigarettes is uncertain, we believe that clearly counseling patients against e-cigarette use, as well as other tobacco use, is prudent." Presumably, the authors would prefer that smokers stick with the FDA-approved smoking-cessation products that have a success rate that ranges from 2% to 7% when used as directed.

It is estimated that there are now a million former smokers who achieved their smoking abstinence by switching to e-cigarettes. It isn't at all prudent to recommend that they stop using e-cigarettes and risk relapse, nor is it prudent to steer current smokers away from a product that has a success rate that ranges from 63% to 80% based on the three surveys mentioned above.

Central Michigan University: Just Keep Smoking, Kids

A Central Michigan University (CMU) official recommends that students stick with smoking real cigarettes. Shaun Holtgreive, associate director of Residence Life at CMU, announced that electronic cigarettes are banned for indoor use anywhere on campus. Holtgreive claims to have studied e-cigarettes and says, “research has shown they give off noxious chemicals in the vapor expelled when smoked.”

If the pronoun “they” refers to e-cigarettes, Mr. Holtgreive has a credibility problem. No such research exists.

Smoke contains tar, carbon monoxide, particles of ash, and thousands of chemicals created by the process of combustion. Many of these are present in exhaled tobacco smoke. The vapor from an e-cigarette does not contain any of these constituents because nothing is burned.

Research has shown that, in an e-cigarette cartridge containing nicotine extracted from tobacco, the liquid has trace amounts of tobacco specific nitrosamines. The FDA pointed this out when they announced the results of their testing. However, the agency neglected to mention that the same “carcinogens” are present in FDA-approved nicotine products, in roughly equivalent amounts. [1,2] A trace amount of a tobacco humectant, diethylene glycol was found in the liquid from one cartridge. The FDA did not find any harmful chemicals in the vapor. Numerous other laboratories have found no harmful chemicals in the vapor. [3]

Surveys of e-cigarette consumers have shown that a sizeable majority—up to 79%--of e-cigarette users become former smokers. [4] Holtgreive wants these former smokers to go the designated smoking area and be exposed to second-hand smoke when they use the device that is keeping them smoke-free. He said these regulations are to keep a safe environment for students and those around them.

These same surveys show that over 90% of users are reporting health improvements. “Positive effects reported with ecigarettes included their usefulness to quit smoking, and the benefits of abstinence from smoking (less coughing, improved breathing, better physical fitness),” stated researcher Jean-François Etter. [5]

In the August 2010 issue of Cancer Epidemiology, Biomarkers & Prevention, researchers from Virginia Commonwealth University reported on a clinical trial comparing health effects of subjects’ own brand of cigarettes to two brands of electronic cigarettes and to sham smoking. Own brand and both brands of electronic cigarette significantly decreased tobacco abstinence symptom ratings. Like sham smoking, the two brands of electronic cigarettes had no significant impact on plasma nicotine levels, heart rate, or exhaled carbon monoxide. [6]

There have been numerous reports of people who had no intention of quitting smoking spontaneously losing their urges to smoke tobacco soon after they began using an e-cigarette. Allowing indoor use of e-cigarettes provides an incentive for continuing smokers to give the products a try. Treating e-cigarette users as though they were exhaling smoke sends a message: Just keep smoking, kids.

Email Message to Public Citizen

I am confused. Your web site states "Public Citizen serves as the people’s voice in the nation’s capital."

And yet, we see your organization's name on the Amicus Brief filed on behalf of FDA in Smoking Everywhere versus FDA. Either your organization cares nothing for the health and welfare of the people, or you have been snookered.

Perhaps you fell for one or more of the many half-truths, unsupported fears, or outright lies you have been told about electronic cigarettes. Here are the facts, with sources cited:

Purpose - Electronic cigarettes were invented as a way to provide smokers who can't or won't quit with a substitute that is less hazardous than inhaling tobacco smoke. [1]

They were not invented as a way to outfox indoor smoking bans. They were invented in China. China doesn't have such bans.

They were not invented to be an NRT "smoking cessation" product. NRTs are purposely low-dose with the ultimate aim of "curing" nicotine addiction.

Target Market - Adult, committed smokers.[2] Ask the people/organizations claiming that electronic cigarettes are being marketed to children, "What percent of customers are under age 18?" I'd be willing to bet they can't do this, because they haven't bothered to actually investigate it. You can check the results of a survey (n=303) conducted by the University of Alberta [3] to learn that 55% of customers are between 30 and 50, and 32% are 51 years or older. All were previous smokers. In an ongoing survey (currently over 1,100 responses) being conducted by CASAA [4], we find 53.2% between 30 and 50, with another 29% age 51 years or older, and 84.5% smoked for 10 years or more.

Success Rate as Smoking Alternative - The University of Alberta Survey [3] shows that 79% are using them for a complete replacement for traditional tobacco cigarettes. An additional 17% are using them as a partial replacement, and only 4% use them in addition to tobacco cigarettes. The CASAA survey [4] shows that only 17.9% of users continue to smoke (some) tobacco cigarettes and that 75.2% report that they now use no smoked or smokeless tobacco products at all.

Toxicity - Based on number and quantities of harmful chemicals, electronic cigarettes appear to be at least 1,000 times less dangerous than tobacco smoke.

The FDA's press release concerning lab tests conducted on 18 cartridges gleefully announced that the products contain carcinogens and "a chemical used in antifreeze". If you read the actual lab report [5] you will find that no quantities are specified for the carcinogens -- Tobacco-Specific Nitrosamines (TSNAs).

You can, however, find in a report issued by Health New Zealand that a 16 mg. electronic cigarette cartridge contains 8 nanograms of TSNAs -- "This amount is extremely small, equal for example, to the amount reported to be present in a nicotine medicinal patch. (8 ng in 1g = eight parts per trillion)." [6]

To put this quantity in perspective, consider the fact that a pack of Marlboros contains 11,190 ng/g of TSNAs. [7]

Tobacco cigarettes also contain the "ingredient used in antifreeze." However, in addition, tobacco cigarettes contain arsenic used in rat poison, hydrogen cyanide used in gas chambers, formaldehyde used to embalm dead bodies, polonium radiation dosage equal to 300 chest X-rays in one year, and many more harmful substances that you will not find in electronic cigarette liquid or vapor.

No smoke - Electronic cigarettes use the process of vaporization, rather than combustion. Thus, the user does not inhale tar, carbon monoxide, or particulates. As you might guess (see next item), the lack of these substances as well as the extreme reduction in toxins and carcinogens appears to have a beneficial effect on the health of the users. Consider the bystanders as well. A tobacco cigarette remains lit, producing sidestream smoke. An electronic cigarette does not produce vapor until the user inhales, and the vapor does not go into the surrounding air until the user exhales. The vapor was also tested by Health New Zealand and pronounced to be "harmless, inhaled or exhaled." [8]

Beneficial Health Effects - The majority of University of Alberta survey [3] respondents reported that their general health (91%), smoker’s cough (97%), ability to exercise (84%), and sense of smell (80%) and taste (73%) were better since using e-cigarettes and none reported that these were worse. In the CASAA survey [4] 91.3% report better lung function/easier breathing and 80% report increased lung capacity. Over half report reduced coughing, increased stamina, and sleeping better.

Adverse Health Effects - The CASAA survey [4] asked respondents about adverse effrects, rated by frequency. Dry/sore throat (3.3%), Dry Skin (1%), and Increased Phlegm (1%) were reported as being experienced frequently. These symptoms can be annoying, but are by no means life-threatening.

In contrast, two of the drugs approved by FDA for smoking cessation have resulted in serious adverse effects including seizures, major depression, suicidal ideation, and deaths, and now carry an FDA "Black Box" warning. [9]

In his 32-page opinion [10] accompanying the injunction against FDA in the aforementioned federal case, Judge Leon wrote:

"I am not convinced that the threat to the public interest in general or to third parties in particular is as great as FDA suggests. Together, both Smoking Everywhere and NJOY have already sold hundreds of thousands of electronic cigarettes, yet FDA cites no evidence that those electronic cigarettes have endangered anyone. Nor has FDA cited any evidence that electronic cigarettes are any more an immediate threat to public health and safety than traditional cigarettes, which are readily available to the public."

After considering the facts, I'm confident that you will agree that the public health dangers of electronic cigarettes have been greatly exaggerated by the FDA and the other organizations named in the Amicus Brief. As the surveys show, those who have switched to vaporized nicotine are enjoying the same kind of health benefits seen by those who quit all nicotine use. The real danger to public health lies with the possibility that FDA wins this case and immediately removes electronic cigarettes from the market. What will be the result?

In the CASAA survey [4], 72.2% indicate that it is likely or very likely that they will go back to smoking if electronic cigarettes become unavailable. Do you really want to be party to that end? Furthermore, consider the fact that the smoking prevalence rate has stagnated. Think of the over 40 million continuing smokers, who have tried over and over to quit, who might succeed at substituting vaporized nicotine for inhaling tobacco smoke--but not if the products are banned.

If you want to serve as "the people's voice," we are the people. We are being victimized by an overzealous government agency and non-profit organizations that claim they want to help people stop smoking. Instead, they are throwing all of their power and money into taking off the market the one product that finally worked for us. Look at both surveys. See how many products we tried in our attempts to quit. By insisting that "quit" means giving up all nicotine, these organizations are literally killing us with their "kindness."
