I ended up trying heroin and thought it was okay. I didn't get hooked on it. Used for about two weeks and then quit. Just set a limit for yourself of the total number of times you will try it or the total number of grams you will use in your life and if you stick to that you will be fine. I found it to be less addictive feeling than meth. But from experience with seeing others I can tell you that it is a sneaky drug. Nobody thinks they will get addicted to it until they do. And then it is all down hill. So just make sure not to use enough to get addicted. I think it would take pretty regular use for several (more than two) weeks for this to happen though. I sniffed and smoked though. IV seems to get people hooked a lot faster.
