I don't / haven't used it but would like to think that if I ever have an illness that causes severe pain that other painkillers can't touch, it would be an option. I doubt that I could troll the streets looking for it if I were in that condition and don't think I'd like to put anyone in the position of going to jail to help me out. Very sad and silly when there are so many big pharma drugs that cause so much more harm. It is upsetting to me, too.
