New Scientific Tests and Studies Point to Electronic Cigarette Safety and Effectiveness
The electronic cigarette industry has exploded. According to Medical Organizations supporting Vaping and Electronic Cigarettes (M.O.V.E.) over 29 million smokers throughout the world have discovered that tobacco free, smoke free e-cigarettes satisfy their smoking cravings without having to ingest the 4000+ dangerous chemicals found in traditional tobacco cigarettes.
More physicians and medical organizations, including WebMD, are recognizing the fact that e-cigarettes have tremendous potential for THC or Tobacco Harm Reduction and the FDA is now reviewing the scientific evidence behind this fact.
Although the ingredients in e-cigarettes are all FDA approved, many people are still concerned about e-cigarette safety. It’s reassuring to know that several important scientific tests have already been performed prior to regulation. Here are the most significant to date:
Public Health England published a report that made headlines around the world. The agency found that e-cigarettes have become the number one quitting aid used by smokers. In addition, the report said the health risks associated with e-cigarettes use are minimal when compared to the harm associated with smoking cigarettes. This was an eye-opener for nearly half of all adults worldwide who, according to PHE's study, perceive e-cigarettes to be at least as harmful as traditional tobacco.
The American Cancer Society, an organization that long maintained they do not endorse vaping as a way to quit smoking, received some eye-opening and unexpected results in their Facebook survey. 95% of the 3,384 comments from smokers attributed “vaping” as their only successful way of quitting tobacco cigarettes.
E-Cigarettes Are Less Addictive Than Cigarettes
A study of long-term tobacco users, led by Jonathan Foulds, professor of public health sciences and psychiatry, Penn State College of Medicine determined that electronic cigarettes appear to be less addictive than tobacco cigarette.
This large-sample study which received world-wide publicity, is helping to improve one of the most misunderstood aspect of vaping; “how various nicotine delivery devices lead to dependence”.
According to Dr. Foulds,
“We don't have long-term health data of e-cig use yet, but any common sense analysis says that e-cigs are much less toxic. And our paper shows that they appear to be much less addictive, as well. So in both measures they seem to have advantages when you're concerned about health.”
Also noted in the report are that e-cigarettes have positive implications for for smoking cessation.
E-Cigarettes Are Truly Effective at Helping More People to Quit Smoking Tobacco
A new study on the effectiveness of e-cigarettes challenges the negative views of some public health experts. The study led by Professor Robert West of the University of London's department of epidemiology and public health surveyed people who had stopped smoking in a 12-month period between July 2009 and February 2014. Those using e-cigarettes were around 60% more likely to quit than those using nicotine replacement therapy or just willpower.
Electronic Cigarettes Decrease Nicotine Addiction
A study presented at the 2014 annual conference of the Society for Research on Nicotine and Tobacco (SRNT) and conducted by doctors at the Penn State University College of Medicine, Department of Public Health Sciences, Hershey, PA. showed surprising new evidence that nicotine addiction levels are actually decreased, not increased, in smokers who have switched to electronic cigarettes.
The study which included 2,368 electronic cigarette users measured their level of dependence on e-cigarettes in comparison to their level of addiction to tobacco cigarettes. Results showed that dependence on e-cigs was “significantly lower than it had been on cigarettes” and that e-cigarette users are “significantly less dependent on e-cigs than they were on cigarettes prior to switching”.
Although preliminary, the study was an important indicator that electronic cigarettes may help tobacco smokers to quit by eventually freeing them from nicotine addiction.
A groundbreaking study by Dr. Konstantinos Farsalinos, confirmed the verity of the Penn State study when 19,441 participants from all over the world tested the effectiveness of e-cigarettes on smoking cessation.
81% reported that they had completely substituted smoking with e-cigarette use, while the rest reduced cigarette consumption from a median of 20 to 4 cigarettes per day.
One fifth of the participants used more than 20mg/ml levels of nicotine in their e-cigarette e-liquids. This evidence supports Dr. Farsalinos’ support of electronic cigarettes as a smoking cessation device, as well as his criticism of the European Union's overly strict nicotine regulations which he has called, “inappropriate”.
American Journal of Health Behavior
A study of 28 adult smokers—none of whom were interested in quitting, were asked to vape e-cigarettes for a week long trial. Nearly 90 percent reduced their use of tobacco cigarettes during that week. Nearly one-third of those smokers cut their tobacco cigarette use in half, and four participants quit smoking tobacco cigarettes completely.
Nicotine absorption was also measured during the test and was found to be on par with nicotine-replacement products approved by the Food and Drug Administration.
According to Dr Richard Carmona, former Surgeon General under the George W. Bush administration,
“If we stopped tobacco use today, 80 percent of the lung cancers would go away—not today, but in the future.”

Drexel University School of Public Health Study of E-Cigarette Safety
A study conducted by Professor Igor Burstyn, confirms that chemicals in electronic cigarettes pose no health concern for users or bystanders. This was the first definitive study of e-cigarette chemistry and findings show that there are no health concerns based on generally accepted exposure limits.
The study made over 9,000 observations about the chemistry of the vapor and e-liquid chemistry. Dr. Burstyn determined that the levels of contaminants e-cigarette users are exposed to are insignificant, far below levels that would pose any health risk.
The Consumer Advocates for Smoke-free Alternatives (CASAA) sponsored the Drexel study, commenting,
“There is no health risk to bystanders. Proposals to ban e-cigarettes in places where smoking is banned have been based on concern there is a potential risk to bystanders, but the study shows there is no concern.”

Journal of the American Medical Association
Dr. Neal Benowitz who served on the FDA’s Tobacco Products Scientific advisory committee, co-authored a report on e-cigarettes in which they were tested against tobacco cigarettes. Two important statements were made supporting tobacco harm reduction and e-cigarette effectiveness in helping smokers quit traditional cigarettes.
Benowitz said e-cigarettes,
“likely pose less direct hazard to the individual smoker than tobacco cigarettes and might help smokers quit smoking or reduce harm by smoking fewer tobacco cigarettes.”

Italy’s University of Catania
In a study published in the journal PLOS One,
300 smokers who had not intended to quit tobacco cigarettes were given e-cigarettes and were closely monitored during the course of 2 years.
They were given two different nicotine strengths of a popular e-cigarette model. The purpose of the study was to see whether a non-nicotine choice e-cigarette was effective in helping smokers get off tobacco cigarettes easily, and whether those given non-nicotine e-cigs would go through difficult withdrawal symptoms.
The results favored e-cigarettes, in that with or without nicotine, the smokers “decreased cigarette consumption and elicited enduring tobacco abstinence without causing significant side effects.”
Onassis Cardiac Surgery Center
In another study led by Dr. Konstantinos Farsalinos it was shown that electronic cigarette use has “no immediate adverse effects on coronary circulation (blood and oxygen supply to the heart)”. This was the first study ever to evaluate the toxicity of e-cigarette vapor.
According to Dr. Farsalinos,
“The results are even more impressive when you consider that we compared one tobacco cigarette with electronic cigarette vapor equivalent to 3 cigarettes….20 of the electronic cigarette samples tested were virtually non-toxic and only one sample showed mild cytotoxicity. The worst-performing liquid had 795% higher cell survival relative to tobacco smoke.”

Frauanhofer Institute for Wood Research WKI in Braunschweig
The Fraunhofer Institute tests on electronic cigarettes addressed concerns about dangerous emissions and particles contained in e-cigarette vapor.
Medical News Today interviewed Dr. Tobias Schripp, scientist at Fraunhofer WKI and co-author of the study.
Quoting the report –
“The researcher and his colleagues were unable to find any formaldehyde emissions from the e-cigarette. Regular cigarettes, on the other hand, surpassed the guideline value of 0.1 ppm (parts per million) for indoor air quality under the given test requirements. Vaporized propylene glycol was given off from both tobacco cigarettes and e-cigarettes.”

The studies cited here are only a few of many new scientific controlled studies being conducted in advance of final e-cigarette regulations. We're confident ecig safety and effectiveness will be confirmed and the surrounding controversies will become a thing of the past.
UPDATE: OCTOBER 2016
The scientific consensus behind e-cigarettes continues to strengthen this week, with two separate studies – one in England and one in India – confirming that the devices are an effective tool for smokers who want to quit. Meanwhile other researchers found that despite previous alarmist claims, e-cig vapour causes no detectable damage to lung cells.
