i have been through many months of drug and alcohol classes but that was included in my probationary terms...i say just stick with it, my class helped me stop drinking and i now have a lot more self control when it comes to weed. however the only reason my classes did anything was because my teacher was a former user and the class was made up of poeple who did some hard time for substance abuse...i dont believe in the hwole regurgitated twleve step bullshit from a teacher
