What to do about a person's issues w/ pot and a stroke.?

Pot opinions have changed lately with alot of medical professionals. Most psych docs actually off-handedly not stopping pot smoking, because most people when they smoke pot become more relaxed, and duh, less stressed. I'm Bi-Polar and all my psych docs knew I smoked pot, never ever asked me or suggested that I quit. I'm much easier to deal with. Plus he's a grown man, have you done everything he told you to or wanted you to do? And he's YOUR DAD!!
