The main study finding was as follows: "The assessment of lung function demonstrated that neither a brief session of active e-cigarette smoking nor a 1 hour passive e-cigarette smoking session significantly interfered with normal lung function. On the other hand, acute active and passive tobacco cigarette smoking undermined lung function, as repeatedly shown in previous studies."

While I agree with the editorial, it is quite a condemnation of the current field of tobacco control research.

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.

The benefits of electronic cigarettes are clear: they help many smokers to quit smoking. They are especially advantageous to smokers who have failed to quit using traditional methods. Taking these products off the market is essentially condemning many smokers to continued smoking by taking away a viable option for them to try to kick the addiction.
