I smoke medical marijuana, I have a card and when I can afford it I get some. It helps a lot but once the tolerance builds I can't afford it anymore. Such a shame because it is better than NSAIDs or painkillers.
Paranoia is magnified, and anxiety attacks do happen on this stuff. Of course, I am probably having paranoia and anxiety 24/7 I just got used to it somehow. Marijuana just magnifies it sometimes, but I sure like not caring about the pain.
One of the clinics give free frozen juice cubes that I drink everyday. I don't know if it is helping but I drop a cube in my water every day secretly hoping it cures me some way or another.
