The Amarillo Globe-News ran one of those throwaway eCig articles you typically see in newspapers these days. The article quoted a local vape shop owner who can't say e-cigarettes are useful in quitting, but quit smoking himself using e-cigarettes. Then there was the local medical professional who based on one study, declared eCigs are an unfit method of quitting but instead recommended cutting down slowly, which is a method that is even less successful than most traditional methods.
Flippin cited a June 2012 study published in the American College of Chest Physicians’ CHEST Journal that found e-cigarettes caused “adverse physiologic effects after short-term use that are similar to some of the effects seen with tobacco smoking.”
“I know that there’s an increase in nitric oxide (levels in e-cigarette users), which is one of the mediators that we see that brings about inflammation in the lungs,” Flippin said.
Flippin said he does not recommend e-cigarettes to patients who are trying to quit smoking, but instead encourages them to reduce daily the number of cigarettes they smoke and to see if a physician would prescribe them nicotine patches or similar stop-smoking aids. Moral support from friends, family or support groups also can help, he said.
I don't think even the anti-smoking groups recommend gradually cutting down, since it's an all or nothing deal with many of those groups. Also, there's the whole idea of relative risk which seems to be lost on some people.
