A South African governmental study of 349 smokers shows that e-cigarettes are an effective smoking cessation aid. At the end of the two-month study, 45 percent of the participants had quit smoking. Six percent had quit by the end of the first two weeks, and more than half of the participants reported that they had more energy and felt that they looked better.
Medical professionals who participated in the study expressed overwhelming support of electronic cigarettes for smokers who are trying to quit. “An e-cigarette is the most effective treatment method on the market for quitting tobacco smoking,” says Dr. Clifford Hulley. Despite what supporters feels is overwhelming evidence, the FDA has not endorsed e-cigs as an official smoking cessation method. Martin Veller, the head vascular surgeon at the University of Witwatersrand has seen results in his own family. “My wife smoked traditional cigarettes heavily until the moment she replaced them with Green Smoke electronic cigarettes.” He advises his patients to consider e-cigs for their nicotine addiction instead.
Pretoria doctor Kishore Deva quit smoking himself using electronic cigarettes. He estimates that ten to fifteen puffs are the equivalent of the nicotine delivered in one tobacco cigarette, and advises that it is not nicotine that is responsible for the health risks associated with traditional cigarettes.
Another study performed by Health New Zealand in early 2009 determined that electronic cigarettes are not only safe as compared to smoked tobacco, but they are also safe in absolute terms. Head of research Dr. Murray Laugeson explains, “An electronic cigarette vaporizes very small quantities of nicotine dissolved in propylene glycol, two small well-known molecules with excellent safety profiles, into a fine aerosol. Each puff contains one third to one half the nicotine in a tobacco cigarette’s puff. The cartridge liquid is tobacco-free and no combustion occurs.”
