Experts: E-cigarettes less harmful than smoking, but only for full switchers

A group of nicotine addiction experts published recommendations for doctors on discussing e-cigarettes with smokers. They state that adult smokers who completely switch to e-cigarettes are likely significantly less harmed than continuing to smoke, though abstaining from nicotine entirely remains preferable. The guidance is conditional on complete switching and adult use, and it does not address youth or dual use.
