i'll add my 2 bits to the conversation, then....
i'm 38yo, the first time i smoked (before gym class, in 1986) i got sick as a dog. but the second time i tried (that same afternoon, right after school) i got hooked. and i kept on smoking, without a break, until last December. when i quit for good (until i change my mind, that is...). addictive? i guess, yes. but it never stopped me from doing what needed to be done (it might have delayed the process, somehow

). i loved the relaxed feeling it gave me. i gave it up when i realized that my paranoia level greatly increased right after smoking, something i had not wanted to recognize before. the first few days off the weed were hard, and i did spend a couple of night sweating my ass off in bed. but that was it. no other side effects, no withdrawal symptoms, no shakyness, no NEED to have it at all costs. it is, after all, just a fucking plant....
cigarettes, that's a whole another story.
started smoking them more or less at the same time i started weed. and gave up 16 days ago (i'm on a CLEANSING MY BODY crusade

).
now, that's fucking hard as hell. that's making me crazy. everything i do is followed by reaching into my pocket for one. eating, drinking, waking up, having an argument, feeling stressed, stepping out of the house, getting behind the wheels, even going to the bathroom...
that's addictive, the shit they put in them.
jones, listen up:
pick a day when you know you have NOTHING to do. go the the store, buy chips, ice cream, chocolates, candies, cookies and the likes. you will NEED them. call up one of your friends (you HAVE to have a friend that smokes, guaranteed) and ask him to hook you up. lock yourself in the house, alone is even better. put on some cool music (reggae is best

) or a comedy show or a funny movie. smoke a fatty. get back to us.
peace.
