It sure did for me — I went from a twenty year long, two pack a day cigarette habit to e-cigarettes a month ago. I immediately preferred vaporization to smoking, and honestly haven't wanted an ordinary cigarette since.
I tried e-cigs last year. They weren't that robust (I ordered a Chinese package from Taobao) and didn't do anything for me besides break. Maybe I'll try again when I can find something higher end.
