Electronic Cigarettes: A Short Review
Bertholon J.F., Becquemin M.H., Annesi-Maesano I., Dautzenberg B.
From our review of the literature and bearing in mind the long experience with theatrical mists, the short-term toxicity can be considered to be very low
Many smokers see the e-cigarette as a good way to quit smoking
Peering through the mist: systematic review of what the chemistry of contaminants in electronic cigarettes tells us about health risks
Threshold Limit Values (TLVs), were conducted under “worst case” assumptions about both chemical content of aerosol and liquids as well as behaviour of vapers.
There was no evidence of potential for exposures of e-cigarette users to contaminants that are associated with risk to health at a level that would warrant attention if it were an involuntary workplace exposures.
Current state of knowledge about chemistry of liquids and aerosols associated with electronic cigarettes indicates that there is no evidence that vaping produces inhalable exposures to contaminants of the aerosol that would warrant health concerns by the standards that are used to ensure safety of workplaces. However, the aerosol generated during vaping as a whole (contaminants plus declared ingredients) creates personal exposures that would justify surveillance of health among exposed persons in conjunction with investigation of means to keep any adverse health effects as low as reasonably achievable.
Exposures of bystanders are likely to be orders of magnitude less, and thus pose no apparent concern.
Characterization of potential impurities and degradation products in electronic cigarette formulations and aerosols

Most potential impurities or degradation products were not detectable.
Impurities or degradation products found were below occupational exposure limits.
Metal emissions from e-cigarettes: a risk assessment analysis of a recently-published study
Konstantinos E. Farsalinos, Brad Rodu
EC emissions contain trace levels of metals. For almost all metals, unrealistically high levels of liquid need to be consumed in order for total daily exposure to exceed established limits.
