There are some specific problems with survey studies that could lead to an overestimation of the benefits of electronic cigarettes. One major problem is that a survey study of the use of advanced vapor products would result in a severe bias towards finding a high level of effectiveness of these products. The reason? By the time smokers advance to use products like open-ended systems, they have already experienced success, fulfillment, and enjoyment with vaping. In other words, limiting the sample to users of advanced vapor products filters out the majority of e-cigarette users, who do not experience great success and therefore don't go on to the more advanced products.

Actually, these "guys" are in the quitting business, not the addiction business. The overwhelming majority of electronic cigarette users are people who are already addicted to cigarette smoking. And the reason they are using these products is because they want to overcome their addiction to smoking. They want a safer product that can help them get off cigarettes, or at least to greatly reduce their cigarette consumption in order to protect their health. Very few never smokers are regular electronic cigarette users, and there is at present no evidence that the use of electronic cigarettes leads to nicotine or smoking addiction in anyone who was not already a tobacco user.

At the same time that the tobacco companies and the U.S. Department of Justice reached a consensus on the location of the tobacco industry corrective statements, the Rest of the Story has reached a consensus on the text and location of a set of corrective statements it is ordering that CDC and several anti-smoking groups and advocates make, in the wake of last year's revelation that they lied about the dangers of electronic cigarettes.

If "they are not harmless" is the worst that opponents can say about electronic cigarettes in 2014, then there doesn't seem to be much of a controversy over whether these products are much safer alternatives to smoking. Likewise, there doesn't appear to be much of a controversy over whether switching to e-cigarettes is a wise choice for smokers who want to quit but feel unable to do so cold turkey (which is, of course, the best option).
