They don’t do shit for me. I could vape an entire cart and still want a cigarette just as much, if not more, than before I used the e-cig. The nicotine gum did a better job of curbing my cravings for a cigarette. So did Prozac; but that was given to me for depression and also gave me ED, so I mean… You wanna quit smoking or you want a working penis? You can choose 1. 😖
