Here's my honest opinion....
If you really had to ask a bunch of people you don't even know ,across the internet, if you should, then that tells me that you're aren't mature enough to. People may tell you "NOOBZ! it's not bad for you at all!" but the problem is that if you're not mature enough and responsible enough, it can be a huge gateway drug to other things that are really bad for you. From the looks of it, I say that you're not mature enough yet, and don't take that as an insult, because it's not. Wait until you can make a responsible and informed decision on you own. Nobody can tell you when you're mature enough but you. Don't rush it.
