Yesterday, I explained that the of electronic cigarettes by Stan Glantz and colleagues published this week in the journal Circulation is because it draws conclusions about the efficacy of e-cigarettes for smoking cessation from studies that were not designed to measure such effects in the first place. These studies did not examine smoking cessation rates among a cohort of smokers who were identified at baseline as using e-cigarettes with the intention of quitting smoking. Moreover, smokers who use e-cigarettes are likely more heavily addicted to nicotine and may be more resistant to quitting, thus making inferences about cessation effectiveness from these studies inappropriate.

While the studies were not funded by a tobacco company, the study products were provided free of charge by U.S. Tobacco. Previously, this co-author did conduct tobacco industry-funded studies, which he acknowledged in a 2008 publication. This funding apparently goes all the way back to at least 2000. In addition, the researcher used to do consulting work for Star Scientific, U.S. Tobacco, Liggett, and Santa Fe Natural Tobacco Company, although none of that consulting occurred within the past three years.

The relative safety of e-cigarettes over tobacco cigarettes is their primary selling point.

We have today published new advertising rules for e-cigarettes to ensure they continue to be promoted in a responsible way. The new rules add to those already in place and will come into effect on 10 November 2014.
