6. Regulation of heating temperature and protection against overheating and dry puffs.

Some of the most important conclusions in epidemiologic research have come not from large case-control or cohort studies or clinical trials, but from case studies or case series, or as Dr. Frieden would say, "anecdotes."

Similarly, the study found that 2.9% of the baseline nonsmokers had ever tried an electronic cigarette in the past year. It could have been that the respondent took a single puff on an electronic cigarette and never took another puff.

If the electronic cigarette companies are acting fraudulently, then I guess so am I. If you review my blog, you will find that I referred to what comes out of electronic cigarettes as a vapor until quite recently. It wasn't until several months ago that I learned that it is actually an aerosol rather than a vapor. I wasn't using a tobacco industry tactic; I was simply using the term that was most commonly used, and I was using the term that I believed was correct. I don't have any reason to believe that electronic cigarette companies were doing anything different. Moreover, it is not fraudulent for these companies to try to connote reduced harm. Electronic cigarettes are undeniably less harmful than real cigarettes.
