More evidence that e-cigs inhibit quitting conventional cigs in the real world
Ling and Popova recently published "Alternative Tobacco Product Use and Smoking Cessation: A National Study" in American Journal of Public Health that , like earlier research, found that an important reason that adults tried e-cigarettes (as well as smokeless products) was because they through they would help them quit smoking conventional cigarettes.
Ever use of e-cigarettes was not associated with being a successful quitter (OR 1.09; 95% CI 0.72-1.65) but was associated with being an unsuccessful quitter (OR=1.78, 95% CI 1.25-2.53) compared to people who had never tried to quit.
This evidence is from a cross-sectional study (i.e., a snapshot in time) rather than following the same people over time (a longitudinal study), so by itself does not allow making causal conclusions. Taken with the two published longitudinal studies, one of which found that e-cig use had no effect on quitting and the other of which showed lower quit rates for e-cig users, it does add to the case that the loudly made claims that e-cigs help smokers quit are wrong.
