Woah thinking too deeply there. Yes your body releases endorphins to help relieve pan. But when you actually FEEL pain your body has done all it can do. It can't help you anymore. That is why you take pain pills. I have a bladder disease. It's very painful. So I take pain pills every now and then for it. Smoking weed for me while in pain helps to relieve the pain just like I would have taken a pain pill. Except usually it doesn't make ALL of the pain go away. Just takes the edge off. So smoking weed while in pain does not make you get any more high than you would be if you weren't in pain. But if you mix pain pills with weed yeah you will be extremely relaxed. Not any more HIGH than normal. But more relaxed.
