i highly recommend not trying it. i have never done it myself. but it is extremely bad for you even if you do it once. i dont really know much about it. but there really is no reason to try anything harder. if you smoke weed, just stick to that. look up articles on things that it does to your body. it will probably change your mind. even doing it once is horrible. please dont try it. i dont really have anything else to say because i cant relate to this topic, but i hope i helped.
