Quitting smoking aided by e-cigarettes

A team of New Zealand researchers found more people stopped smoking for at least six months with e-cigarettes than with nicotine patches, although without statistical significance.

The study also suggested e-cigarettes were comparable to nicotine patches in terms of safety, although longer-term data was needed.

E-cigarettes simulate cigarette smoking by heating a nicotine solution encased in a battery-powered cigarette-like stick, to produce a vapour.
