OK , I smoke Cigarettes for 23 years at two packs a day. First thing in morning was two cigarettes back to back then start my day. My Grand father dies of throat cancer. A horrible death. I didn't want to go out like he did. So I wanted to stop but tried cold turkey and failed every time. My Doc gave me Chantix and I was done smoking in 3 weeks and it's been 4 years and have not went back. Smoke MJ like a chimney at times and even sit with smokers and breath in the smoke with NO URGE to ask for one. Actually they smell gross. Like unwashed ass. They say people have thoughts of suicide on Chantix, but IMHO you need to have that mind set to begin with. THE POWER OF THE MIND! :thumbsup:
