I know this may be a difficult question to answer but I have a dillemma between these two. I have a buddy who has these morphine pills (m with a square on one side, 100 on the other). I know that morphine has a much higher bioavailabilty when you IV so I'm thinking it could be a good idea. However, I'm worried that these pills would gel up if I tried it. On the other hand I could get the 40's but they're expensive. However, I'm completely familiar with OC. Not so much with morphine, especially IV morphine. Does anyone use these or know about how a 100 mg morphine compares to a single OC 40 and if the morphine pills gel up? I'm not looking for anything super scientific just a rough estimate. Thanks everyone.
