I had to stop smoking, about a year ago.
I started using nicotine lozenges. They take some getting use to but will do the job.
However, I always wanted a cigarette. Also, while I did manage to reduce the number of lozenges down to about 3 a day, (lowest size), I couldn't quite face not having them. I suppose I'd substituted one addiction, for another.
Then it occured to me, so what?
The lozenges have a bit of sugar, (teeth and some nicotine. But they are and will always be a better habit than tabaco. I can suck one almost anywhere. I don't smell so much.
And best of all, I have never had to deal with those interminable, smug former smokers, trying to lead me to their promised land, with a mixture of perky stupidity and Protestant suffering.
Just a few thoughts.
