Is marijuana too addictive to be used as a medicine?
Absolutely not. Marijuana is not addictive in the sense that its use requires increasing doses, that you develop a tolerance to it or that there's significant withdrawal symptoms. There are some psychological symptoms that an individual might experience if they've been using marijuana, say to treat anxiety or to treat depression. Obviously if they stop suddenly they're going to have some rebound in their anxiety and depression. But by itself I really don't think that marijuana can be can be called a narcotic, and at most it would be a mildly addictive compound and mostly through psychological mechanisms, not physical.
