I was going to stay out of this and say no more, because to tell a kid not to do something because it's dangerous is like throwing out a challenge to them to do it. However, your last post vege head I find alarming.
You are of an age where you want to experiment with wierd stuff, and that's fine, but before you do, make sure you know fully what you are doing, and getting yourself into. Learn fully how to protect yourself from anything bad that results from anything like this. And learn, that even with that, you are STILL not safe.
Better that you listen to someone who has already experienced these things and can vouch for their dangers. Not me, because I have never used one, I wouldn't entertain having one in my house, or even on the property. They are just bad news, nothing good ever comes of them.
As for beliefs, it pays to have an open mind to everythng, which I do, although, I have my own beliefs, I don't push them on to anyone, I keep them to myself, I am not religious neither.
You would be well advised, Vege-head, to stay away from something you know nothing about. It's not a fun thing, nor it is to be taken lightly.
