"Stop-smoking experts say the devices are not useful for ending cigarette addiction because they do nothing to interrupt the hand-to-mouth behavior that is an integral part of the habit"

B.S. Although, I am not completely off the real cig yet, but I have been cutting down from at least a pack a day to couple a week. It has worked for many people. The reason why it still doesn't work for me is because of the taste. My hands are way more busy compare to smoking the real cigarette. That stop-smoking-expert sure doesn't know what the H he's talking about.

No one knows if it's completely safe, but also no known health issue yet. Yes, I agree with you that it's hard to say, but disagree with the writer and the "stop smoking expert" above. That stop-smoking-expert might have his own method that he's been making his living from.
