Hmm... I have never been around someone that was annoying when they were high. It sounds like this kid is annoying when he is sober too. I would never hang out with someone like that. I don't think weed brings out annoying traits. Actually one time when I was really stoned, I started talking with my mouth full of food. A friend told me. I was really embarrassed, but she was the only one there. That's the only time I can think of anything like that.

I think people see others acting like assholes when they are drunk, then using drunkenness as an excuse to be an asshole, so they decide to do the same thing with weed. Alcohol can make people violent, obnoxious, and overemotional, but I don't think weed does any of these things.
