Electronic (e)-cigarettes are about 95% less harmful to health than tobacco cigarettes, and they might be useful in helping people kick the smoking habit, according to a report commissioned by Public Health England (PHE).
The authors of the report also found that regular users of e-cigarettes are almost exclusively adults who are already smokers. In fact, the rate of youths and adults who smoke cigarettes has continued to decline in England, and there is no current evidence that e-cigarettes are "renormalizing smoking or increasing smoking uptake," they write.
In addition, there is no evidence that e-cigarettes are a "gateway" to tobacco products for teens and young adults. Despite some experimentation among never smokers, e-cigarettes are attracting very few people who have never smoked, the authors, led by Ann McNeill, PhD, professor of tobacco addiction at the National Addiction Centre, King's College, and Peter Hajek, PhD, CClinPsych, director of the tobacco dependence research unit at the Wolfson Institute of Preventive Medicine in London, United Kingdom.
