Electronic cigarettes for smoking cessation: a randomised controlled trial [1]
This 2 year trial randomizing pts between e-cigarettes, placebo e-cigarettes, and nicotine patches was conducted in 657 people. Abstinence from smoking was achieved in 7.3% for e-cigarettes, 5.8% for patches, and 4.1% for placebo. Abstinence rates were strikingly low, and aids to smoking cessation offered no important advantage in this small study.
