Of course he's "addicted" to marijuana, it alleviates something that was deemed a "serious medical problem." Would you say he's addicted to prescription medication because he used it daily to alleviate his ADD and anxiety disorder? I doubt it, but because he uses marijuana (which is a safer alternative) to do the same thing, he he's an addict that's ruining his life.
