Bipolar i smoking marijuana since 1997. cant quit due to withdrawal symptoms?

Addiction: That is your brain and the disease of addition telling you this. If you cannot stop on your own, then asking your family doctor for help is a great place to start. You very well may need to be in treatment for a bit to get past the withdrawals and to begin to learn how to live clean. It is very much a real possibility and not something that is impossible. I wish you well.
