I concur with reesecups is stating here. i can see the point of substituting ecigs for nicotine as a form of harm reduction that may become a valid part of the process leading to quitting, but I personally don't recommend it because smoking ecigs can be addictive in its own right, and may eventually reinforce the smoking habit altogether, thus making the desire to quit more difficult and elusive. I guess that's one way of looking at it, and I'm sure there are others.

On the other hand, people have gradually quit using the patch and other forms of cessation. I think it's up to the motivation of the individual. That's the way it was in my case. My personal level of motivation was the key factor in my ability to quit --- finally -- after several years of tries.
