According to a issued by Columbia University Medical Center, a team of researchers from Columbia University have concluded that electronic cigarettes may serve as a gateway not only to cigarette smoking, but also to illicit drug use and addiction, such as cocaine addiction.

In a December 2010 on treatment for smoking cessation published in the Wisconsin Medical Journal, the conflict of interest statement regarding Dr. Fiore acknowledges that: "Over the last 3 years, Dr Fiore has served as an investigator in research studies at the University of Wisconsin that were funded by Pfizer and Nabi Biopharmaceuticals."

"The next major issue that TPSAC will consider (after menthol), in fact, is dissolvable tobacco products. Now that GlaxoSmithKline has come out in strong opposition to these products and directly petitioned the FDA to remove these products from the market, it is not possible for any TPSAC member who has a financial conflict of interest with Glaxo (or similar companies that manufacture smoking cessation products) to impartially participate in discussions on this matter."

The full effect of using electronic cigarettes on people’s health has yet to be established as e-cigs are a relatively new device and long term effect studies simply do not yet exist. Though there is only limited research at this time, the studies that do exist primarily seem to agree that the electronic method of delivering tobacco to your system is significantly safer than the traditional method of combustible smoking, which exposes the user to noxious smoke and tar. The AHA policy statement read: “To date, relatively little research has been conducted on the human health effects of e-cigarettes.” They go on to cite a study by the American Journal of Preventative Medicine, in which they found that, “no serious adverse effects have been reported in clinical trials with less than 6 months of use compared with nicotine patches.” Users who are trying to quit smoking and using nicotine replacement often report having more success with e-cigarettes as a cessation method for a variety of reasons. Not only do vapor cigarettes deliver the nicotine in a safer way, they also allow the user to have an enjoyable experience, one that is similar to traditional smoking, which many smokers agree is often just as much of a part of their addiction as the nicotine itself.
