So there's absolutely zero chance that OP is suffering weekly nicotine withdrawal from
I light 2-3 cigs on the weekends and that's it
?
I guess I was transported to an alternate universe where nicotine isn't addictive at all to anyone, then. Bye.
Who said that? Of course that he is. As I've already stated, if he smokes a single one then the effect is already there.
Essentially through time there will be more and more cravings on a daily basis. He must be either able to resist them all or he will slowly start smoking more and more often.
Update:
I wouldn't recommend pills for a non existing problem.
