Could you tell me what happens when you go to the doctors about a cocaine addiction?

You get help: Doctors are trained to be non-judgmental, meaning they won't outwardly judge your problem in the same negative fashion that society may have. They are there to help when they can & often can help. A long standing Cocaine addiction often requires the assistance of an addiction med specialist, psychiatrist, counselor, etc. But starting with your regular doctor is a very good 1st step.
