Professor Igor Burstyn of Public Health of Drexel University’s Dept. of Environmental and Occupational health has recently published a new study called
–Peering through the mist: What does the chemistry of contaminants in electronic cigarettes
tell us about health risks?
In a nutshell this is what the study found
By reviewing over 9,000 observations about the chemistry of the vapor and the liquid in e-cigarettes, Dr. Burstyn was able to determine that the levels of contaminants e-cigarette users are exposed to are insignificant, far below levels that would pose any health risk. Additionally, 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.
ACSH’s Dr. Gilbert Ross, a close follower of the e-cigarette literature and regulatory scene, commented as follows: “Prof. Burstyn’s comprehensive analysis should help put to rest the good-faith concerns of some in the anti-smoking community who continue to doubt the safety of e-cigarettes’ ‘second-hand vapor.’ Unfortunately, for the bulk of the harm-reduction haters, this will probably have little impact, since they are refractory to science-based discussion, fixated as they are on their various perverse agendas.”
