A 2013 study on an online version of The Lancet found that people who use
vaporizers are more likely to quit smoking and is as effective as Nicotine Patches in helping
people to stop smoking.
A study conducted by the University of Auckland New Zealand conducted only
the second trial to test the performance of e-cigarettes and the first to assess the
effect of e-cigarette over nicotine patches in helping people give up smoking.

participants who used Nicotine Patches.

Also, 43 out of 100 people cut down smoking by at least half compared with
about 27 out of 100 who used the placebo treatment. However, there wasn’t
much evidence that e-cigarettes worked better than nicotine patches. The
researcher said that the results of the studies they reviewed are far from
definitive, and in time future research may contradict their findings, but that
based on current evidence they said e-cigarettes may be helpful for some people.
