One concern about giving smokers e-cigarettes as a smoking cessation aid is that doing so instantly converts them into dual users (smoking both cigarettes and e-cigarettes), which adds the risks of e-cigarette use to cigarette use. Peter Hajek’s group just published Patterns of e-Cigarette Use and Smoking Cessation Outcomes: Secondary Analysis of a Large RandomisedContinue reading “New paper by Hajek group presents misleading incomplete results about dual use when using e-cigs as cessation aid”

Plain language summary of meta-analysis of ecigs and disease available
Last year we published “Population-Based Disease Odds for E-Cigarettes and Dual Use versus Cigarettes” that showed that some disease risks of e-cigarettes are indistinguishable from cigarettes and for others they on only slightly lower. This paper continues to attract interest, so I prepared a one page plain language summary, together with some frequently asked questions.Continue reading “Plain language summary of meta-analysis of ecigs and disease available”

E-cigarettes increase harm to smokers, so should not be promoted as a harm reduction strategy (in 10 slides)
The tobacco industry has used claims of reduced harm to sell its products since the 1950s with its efforts to promote “safe cigarettes.” “Harm reduction” claims have been central to marketing of e-cigarettes since they were commercialized in 2003. The tobacco industry and its allies continue to use claims of reduced harm to argue againstContinue reading “E-cigarettes increase harm to smokers, so should not be promoted as a harm reduction strategy (in 10 slides)”
New Pesko et al paper supporting e-cigs ignores current science
Several people have asked me what I thought of the just-published paper E-Cigarettes in Historical Context—Innovation, Risk, and Regulation by Michael Pesko, Jamie Hartmann-Boyce, Rachel Fung and Neal Benowitz. Like other similar papers published by some of these people, the Pesko paper relies on the 7 year old 2018 National Academies of Science, Engineering andContinue reading “New Pesko et al paper supporting e-cigs ignores current science”

Inhaled cannabis associated with increased risk of asthma and COPD independent of tobacco smoking
Answering the question of whether inhaling cannabis increases the risks of asthma and chronic obstructive pulmonary disease (COPD) has been complicated by the fact that in the past almost all cannabis smokers also smoked tobacco, so it was difficult to determine whether the observed associations between smoking cannabis and these diseases was really due toContinue reading “Inhaled cannabis associated with increased risk of asthma and COPD independent of tobacco smoking”
