Health.com says "not a successful quitting method". On what research does health.com base this allegation? The survey of European e-cigarette consumers conducted by JP Etter, published in the BMC Public Health Journal indicated that 63% had replaced all their
tobacco cigarettes with use of an e-cigarette. The survey of Canadian, US, and UK consumers, published in the
tobacco Harm Reduction Yearbook 2010 found an even higher success rate: 79%. These people no longer smoke. If that's not successful quitting, what is? The Health New Zealand study referenced by Health.com also stated that the quantity of "carcinogens" in the highest level of nicotine liquid (8 ng) equals the quantity in a medicinal nicotine patch (also 8 ng). In the 6 years the products have been used world-wide (2 years in the US) there have been no poisonings. There have been no serious adverse events reported at all. In fact, 91% of users surveyed state that their health has improved, most notably lung health.
