People get scared easily by drugs. Look, try it but use your brain. A gateway drug is only that if YOU walk through the gate and make that choice. You don't become an addict by trying something once. Don't go crazy on it and don't use it at home by yourself. Experimenting is fine. I tried weed, didn't think much of it really. Don't really care to try it again. I tried coke(snorted it) and it didn't give me the hit I thought it would. It just made me happier, carefree and confident. Which is good but I'd only use it rarely and with friends, never alone.
Don't be scared off by things in life. If you want to try something, try it but be sensible about it.
Edit: Holy fuck that video. The girl in it! Her arm. Ahhhhhhh!
