These data all but destroy the gateway hypothesis. They demonstrate that at the current time, the evidence simply does not support the assertion that the proliferation of e-cigarette use among youth is leading to increased smoking initiation. Electronic cigarettes are not leading to a lifetime addiction to cigarette smoking among our nation's youth.

In my blog , I argued that the cigarette companies cannot possibly be found in violation of the law for using alternative names for their products when the law specifically allowed those products to remain on the market.

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.
