well, weed is not addictive, what you do and the reward responses your brain gets while stoned can seem like an addiction. It's a very bad idea to abuse this stuff daily with schizophrenia just one joint away and the damage it does to your brain in later years can destroy your family and close friends.
If you go cold turkey you'll just drive yourself insane, just cut back for X amount of time and then tell yourself your on a break from it. Exercise and eating well helps alot to feel comfortable away from it, try different herbal tea's too they can help.
Just get another hobby, weed only cures boredom and destroys you brain, too much of any one thing can kill you, in moderation it's ok. Hope this helps
