I used to smoke cigarettes, regulary. Nearly a pack a day, I'd usually be left with 2-5 cigarettes in my pack at the end of the day. I took Chantix to quite, never looked back. Worked great for me. My wife did the same, the Chantix did nothing for her and gave her crazy nightmares. So you just have to try it, I guess. That was many years ago, though. I couldn't imagine paying the prices people do now to smoke. Craziness.
I still smoke weed daily.
