Last week, three Democratic lawmakers -- Rep. Henry A. Waxman (CA), Sen. Tom Harkin (IA), and Rep. Peter Welch (VT) -- sent a to the Attorneys General in their states requesting that the AGs declare that electronic cigarettes fall under the terms of the Master Settlement Agreement (MSA) signed in 1998 with the tobacco companies.

Nevertheless, this does not stop the authors from drawing a conclusion. They conclude, despite their acknowledged inability to draw such a conclusion, that: "e-cigarette use is aggravating rather than ameliorating the tobacco epidemic among youths."

In a recent in Forbes magazine, Jacob Sullum reviews some of the evidence which demonstrates that many former smokers have quit smoking successfully using electronic cigarettes as a cessation aid. Sullum writes:

The paper defends its ethical standards by arguing that it "was consistent with Facebook's Data Use Policy, to which all users agree prior to creating an account on Facebook, constituting informed consent for this research."

It is important to point out that just because the relative risk of cancer associated with filtered cigarettes is lower than that for non-filtered cigarettes, it does not necessarily follow that switching from a non-filtered to a filtered cigarette will reduce one's health risks. It is possible that smokers who make such a switch will compensate because they are used to higher tar levels. It is possible that the observed reduction in cancer risk only holds for lifelong filtered cigarette smokers, as they do not compensate (they never smoked non-filtered cigarettes). In fact, the scientific evidence supports this contention.
