That was dumb on both the girls who drugged her, and the girl herself. It was dumb on the girls because you should never drug someone, I mean that's just a dick move. But it was dumb on the girls part because she's now anti-drug over one bad experience...? Seems like a piece of propaganda to me personally, I have trouble believing it as I read it. If it is real, than this girl seems rather naive.
I can understand her freaking out though, if she truly didn't understand that she had been drugged, than she would probably have assumed she had randomly come down with some random ass terrible sickness or something. When you set out with the intention to get fucked up, it's not such a big deal, but if you get fucked up out of nowhere, and you've never tried a drug before? You're not going to have the slightest idea what's going on.
