My 18 year old difficult child is using pot regularly. (at least 5 days a week) He is BiPolar (BP) and refusing medications. He has a history of heavy drug use (pot,lsd,pcp,alcohol,whatever). He is currently only doing pot and has been off the "hard" stuff for over 2 years. He is doing some huffing, but just a parties and such. Do you think this kid needs a full treatment program to get clean from the pot?
