I'd probably say quitting is different for everybody who does it. All I did was bought a bag of "legal smokable herbs" and when I had major cravings I would smoke some of the herbs. The fact I was smoking something helped, dont know how. Just like my dad he could smoke his tobacco pipe for ages(not inhailing) and then not have a cigarette for a while after. Smoking weed helped aswell...well smoking weed was just fun, made me forget about the tobacco...I started getting used to the legal herbs so I can still make nice joints just with no tobacco although at parties ill smoke joints with tobacco since thats the way most of my friends make them.
