e-cigarettes 'safer than tobacco'

摘要

The use of e-cigarettes as a way of stopping smoking has been endorsed in the first long-term study of its effects in ex-smokers. After six months, it found that people who switched from real to e-cigarettes had far fewer toxins and carcinogenic substances in their bodies than those who continued with real cigarettes. Nicotine patches also appeared to be far safer than tobacco products, according to the analysis of saliva and urine samples. Experts hope the findings will reassure would-be quitters who have been confused by mixed messages about the safety of e-cigarettes.
