I have some purple mallinckrodt brand 30mg morphine pills (m on one side, 30 on the other). I also have some green 30mg extended release morphine pills. I've tried banging the purple ones like I would roxicodone or oxycontin and they gel up pretty bad. I know I'm not getting everything I could out of these. Can anyone advise the best way to prep these? Heat? No heat? Explain please. I'm basically trying to get the most out of these that I can. This gelling issue is annoying as hell.
