I used to smoke cigarettes for a good 7 years or so, and quit cold turkey without much problem. To me nicotine really is more of a mental addiction. I smoke about 2 bowls a day now in my pipe, once in the morning, once in the evening. I just came off a cold/flu and didn't touch my pipe for a good week, didn't really feel any cravings whatsoever. If anything smoking too much tobacco makes me feel kind of jittery and not good, get addicted to morphine and when you don't have it you get a fever, diarriah, and you can't eat until you get a fix and then you feel normal, and then go back to how bad you think a nicotine addiction is. It's all in the head mainly.
