My spouse managed to get a medical supply of mj and that has helped her get back into life, given her pain source is from arthritis and a few other issues it'll probably never be a thing she'll be without but the few studies out there on mj have a positive view of long term pain treatment on it.
Chronic pain is a very serious condition that can ruin lives, it is extremely disgusting to see what has happened with Oxy and heavier penalties are needed.
