Cocaine is a stupid drug to do.
The amount of people I've seen who can't handle it and made a complete idiot out of themselves is ridiculous. One instance I had to physically drag my friend away from someone elses' dorm room door because he was trying to get inside and attack him. Door was covered in his blood because he didn't stop punching until his knuckles had opened up. Prick.
I snorted a line myself once to see what it was like, but that was only out of curiousity. I'd never take it again, because I don't want to turn into an arsehole and spoil everyone elses' fun.
I'm not too big on drugs anyway, same with booze. I'll get wasted but I hate the comedowns.
