I use to smoke weed almost everyday for a year and a half. I wanted to stop, and What I did is I said I am not a drug addict! I took all my weed paraphernalia and threw it out in the trash can and I never looked back.
I think you need to take responsibly for you actions... If you want to stop just do it! find things to do that will take your mind off the addiction. Mine was drinking coffee and playing video games. I have been clean now for 3 months
