Well, if you want my opinion, smoking a fake cigarette with only nicotine, even if you never stop, is already heaps better than just smoking cigarettes. My mother is like that. She smokes her fake cigarette all the time and she doesn't have the slightest willpower in stopping. But I still much prefer that to actual smoking. For one she isn't killing her lungs in the process, and most importantly (to me, selfishly), it doesn't make her smell disgusting. Seriously, I think I might even prefer someone who reeks of vomit to someone who stinks of tobacco. x.x
And honestly, with a nicotine dispenser and a lot of willpower, it should be very doable for you to stop smoking, if the taste of tobacco is your only other problem. I mean, I love the taste of fries, but I haven't had any in, uhm. A few years. Either you need to work harder, either there are other factors. Surely you can think of foods whose taste you love but you can live without, yes?
Also, there apparently exist pills whose purpose, if they work, is to render cigarettes absolutely disgusting for the user. Apparently my cousin tried those, and even though she had a strong psychological/taste-related addiction to cigarettes, as soon as she felt like smoking and lit one, it was just "yuck" and she threw it away immediately. Dunno what those pills are, but if it worked on my cousin whose parents are two compulsive smokers who are seldom seen without their cigarette, then I have a feeling it's pretty effective.
