These flaws are also noted by Dr. Robert West, director of tobacco research at University College London, who that: "the study was not able to assess whether or not for cancer patients who smoke using an e-cigarette to try and quit is beneficial "because the sample could consist of e-cigarette users who had already failed in a quit attempt, so all those who would have succeeded already would be ruled out"."

Whether e-cigarette use precedes smoking or smoking precedes e-cigarette use is a critical question, but it is one which needs to be answered through longitudinal research. We need studies that follow the trajectory of teen tobacco/e-cigarette use over time. That is the only way to determine which comes first.

The study concludes that "e-cigarette use is aggravating rather than ameliorating the tobacco epidemic among youths."

These politicians should stop lying to the American public in order to support their pre-determined agenda. Science, not politics, should guide public health policy in this nation.
