While it is undeniably true that subsequent changes to the tar yield of cigarettes (changes subsequent to the introduction of filters) did not lower the lung cancer risk associated with cigarette smoking, one must be careful in concluding that the introduction of the filter resulted in an increase in lung cancer risk.

But why is it irresponsible?

The letter concludes: "By taking action to apply the MSA to e-cigarettes, you could make a giant stride in protecting kids from a lifelong addiction to nicotine."

2. There is no reason to believe this argument is true in the first place. The percentage of smokers who quit on their own is dismally low. Moreover, the very reason why smokers are trying electronic cigarettes is because they have failed to quit smoking with existing therapies. It is ludicrous to expect that someone who has no confidence in quitting using a traditional methods is suddenly going to quit. In fact, the evidence overwhelmingly shows that without self-efficacy, most smokers are bound to fail. So we are talking about a population of smokers who are not going to quit smoking anyway. Electronic cigarettes are their last best hope. Sure, e-cigarettes are not for everyone and many will fail. But it is simply not true that those who fail are people who would have quit smoking if only they hadn't tried electronic cigarettes.
