The required text for the corrective statements and their required placement is as follows:

There is strong evidence that electronic cigarettes are much safer than tobacco cigarettes. These products contain no tobacco and do not involve combustion. Multiple studies have confirmed that there are only a few chemicals present beyond the nicotine, and so far, only trace or low levels of potentially concerning constituents have been detected - levels which are much lower than in real cigarettes. Users of these products generally report an immediate and dramatic reduction in respiratory symptoms. Moreover, there is strong evidence that electronic cigarettes can be effective in smoking cessation and that they may actually be more effective than traditional nicotine replacement products such as nicotine patches, gum, or lozenges. Even when not effective in promoting complete smoking cessation, these products generally help smokers cut down substantially on the amount they smoke, thus sharply curtailing tobacco cigarette sales.

The rest of the story is nicely summarized by Jacob Sullum in a Reason.com . He concludes:

Instead, these advocates argued that surveys are the best way to study the potential benefits of e-cigarettes. Surveys measure the real-life situation of how e-cigarettes and vapor products are actually used.

If you read the comments to yesterday's post, in which I opine that it is time for Major League Baseball to ban the use of smokeless tobacco by its players during games, you'll see that I was battered by a number of harm reduction advocates. This battering also took place on Twitter and Facebook, where further pot shots were taken.

Similar data from the U.S. would be very helpful. But unlike prior reports, these ones should quantify not only experimentation, but also regular use, stratified by prior status as smokers versus nonsmokers.
