How strange that smoking rates continue to go down at a rate almost inversely proportional to the rate of e-cig usage. How strange, also, that sales of cigarettes continue to go down at a rate almost inversely proportional to the increase in sales of e-cigs and personal vaporizers. While it's true that correlation does not equal causation, in some cases it requires an especially acute level of self-delusion to argue that no relationship exists between one and the other.
Quite simply, if e-cigs were functioning as a "gateway" to tobacco use, then cigarette sales should be increasing. Instead, they're decreasing at an ever-accelerating rate. If they really cared about eradicating tobacco use (which they obviously don't), people like Stan Glantz should be celebrating this fact.
