Electronic cigarettes that heat propylene glycol and glycerol, with or without nicotine and flavours, have been found to be safe based on a new meta-analysis of studies:
An update to the Cochrane review on electronic cigarettes [DOI: 10.1002/14651858.CD010216.pub3] [DX] has restated the findings of the initial research, which was completed two years ago. It found that e-cigarettes are potentially a valuable smoking cessation aid, although there was not enough evidence to conclude that they helped people quit smoking confidently.
The updated review now also includes observational data from an additional 11 studies which found no serious side-effects from using e-cigs for up to two years. Aside from throat and mouth irritation, which commonly dissipated over time, the review's co-author, Jamie Hartmann-Boyce, said "in the short to medium term, we didn't find any evidence that they were associated with any serious side-effects."
Evidence from two trials found that e-cigarettes helped smokers to quit in the long term, but "the small number of trials, low event rates and wide confidence intervals around the estimates" meant that the researchers could not conclude with confidence that e-cigs helped smokers quit more than other cessation aids.

If marriage didn't exist, would you invent it? Would you go "Baby, this shit we got together, it's so good we gotta get the government in on this shit. We can't just share this commitment 'tweenst us. We need judges and lawyers involved in this shit, baby. It's hot!"

The industry already regulates the quality of the ingredients in e-cigs albeit indirectly. Simply mandating that e-cig fluid producers use food grade ingredients is sufficient. Anything past that is just bureaucratic creep and leads to graft, bribery and corruption.
