I used to be obsessed with marijuana. Cravings were bad. And when the stash was empty, even if I had already checked the crib from floor to ceiling and wall to wall for just a little crumb and found nothing, I'd still check again. I have also grown a lot of weed. The obsession required me to smoke morning spliffs, and then smoke up a few times during the day, a couple times before sleeping, and often while sleeping too (not actually while sleeping, but when woken up at night by the urge to piss and so on)... I paid a high-end NY dealer in copper coins once, just to name one of the dumb things I've done, when the fiending was at it's fullest. Not to mention all those far-out crack-head stereotypes, one ends up affiliating one self with during the street-hunt for a dime bag or on a good day an 1/8th!
Then... I got addicted to heroin, and voila! No more Cannabis obsession! Although Cannabis is fucking great, a miracle drug at that, during wd's. Right now I am in ORT with Subutex (Buprenorphine), and compared to when I was on smack, cravings for weed are back again, but not nearly as intense as before... as in I don't get a cringe in my gut every time I smoke the last bud or piece of hash, and I can go comfortably, without that fiending itch for a couple of days, before I end up in a situation again where the smartest thing to do is invest in some Cannabis. These days it's really the simple things in life that give me a god buzz, like a strong cup of coffee, a long bicycle ride, a womans touch etc... We'll see what the deal is once I stop using Bupe!
So you wanna stop itching for ganja? Then do some heroin... No I'm kidding, please don't take me seriously... that's too steep a slippery slope, and I wouldn't recommend it to anyone. Of all the things possible to fiend for, I can peacefully settle for Cannabis. If one must absolutely get sickly obsessed with any drug, I think I'd go with some quality bud as the safest option, but that's just me.
