I believe that such a modified, randomized clinical study is essential to add another line of evidence with which to evaluate the potential benefits of electronic cigarettes. Yes, there are limitations to RCTs, but it makes no sense to throw out the baby with the bath water.

If there were any evidence that electronic cigarettes inhibit, rather than enhance smoking cessation, I too would join Dr. Glantz's camp and oppose electronic cigarettes. But such evidence does not exist. Not a shred of it so far. Not a single study suggests that electronic cigarette use results in lower quit rates than what would occur in the absence of electronic cigarette use among smokers who try these products.

Last Wednesday, the Senate Committee on Commerce, Science, and Technology held a hearing on the marketing of electronic cigarettes. Several senators, including Jay Rockefeller (D-WV), Barbara Boxer (D-CA), and Richard Blumenthal (D-CT) harshly attacked the two electronic cigarette company executives who testified before the committee, calling them liars who are doing harm to the public and comparing them to the Big Tobacco executives of the past.
