E‐cigarettes are battery operated devices that vaporize a liquid solution consisting of ingredients generally regarded as safe for human consumption (89‐90% propylene glycol, vegetable glycerin, water, flavoring) and a small amount of nicotine. (Laugesen, 2008)
Electronic cigarettes are a completely smokeless alternative to traditional cigarettes and are not marketed as a nicotine addiction treatment. (Cahn and Siegel, 2011)
Multiple companies have had their products tested for diethylene glycol and none of the samples have turned up positive. (Siegel, 2011)
A puff of e‐cigarette mist delivers only 10% of the nicotine delivered by a similar puff of smoke from a conventional cigarette. (Laugesen, 2009) (Bullen, 2010)
E‐cigarette use mimics smoking; but, there is no combustion and the user inhales vapor, not smoke. (Cahn and Siegel, 2010)
Do e cigarettes give off secondhand smoke?
The e‐cigarette generates no side‐stream smoke from its artificially lit tip. (Laugesen, 2008)
After the user inhales, the residual aerosol, or vapor, is exhaled into the surrounding air. (Trtchounian, Williams, & Talbot, 2010)
The exhaled vapor of the e‐cigarette is composed of propylene glycol, and contains almost no nicotine; and no carbon monoxide. (Laugesen, 2008)
Is secondhand vapor from e cigarettes harmful?
E cigarette vapor was tested for over 50 cigarette smoke toxicants and none were found. (Laugesen 2009)
“Lacking any active ingredient or any gaseous products of combustion, the PG mist or ‘smoke’ is not harmful to bystanders.” (Laugesen, 2008)
Electronic cigarettes tested did not expose users to “measurable levels of nicotine or carbon monoxide, although both suppressed nicotine/tobacco abstinence symptom ratings.” (Eissenberg, 2010)
What about exploding e-cigarettes?
The news that a man was injured when an e-cigarette exploded in his mouth (Feb. 2012) neglected to mention a few key facts:
The type of e cigarette he was using was NOT the typical e cigarette battery such as the 510 battery sold by Vaping Vamps.
The type of battery he was using was a so-called "mod" battery: a metal tube mod with two batteries inserted for high voltage. This is a completely different "loose" battery design that may not have the same safety features as the sealed battery design used by Vaping Vamps and most other e cigarette companies.
The 510 e cigarette battery sold by Vaping Vamps and regular e-cigarette batteries are NOT affected or prone to anything other than eventually running out of juice. Your battery is safe and will last for many months.
