Combined with , these results suggest that the natural history of electronic cigarette use over time is characterized, in general, by:

Is this really the kind of pure scientific expertise - unclouded by any ideological or political concerns - that we want to be making the critical decisions about how to regulate tobacco products which are killing hundreds of thousands of Americans each year?

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.
