Not everyone pukes from weed. I've never puked from toking up. I've tried gravity bongs, water bongs, joints that could bring a tear to Nelson's eyes, hot knifing, hot boxing, fuck it, I've smoked out of a lot of shit (not a vaporizer though, =() and I've never puked from the smoke.

There's onyl been one time I've puked from smoking, and it wasn't the smoke. I got the munchies real.frickin.bad so I ate enough food to fill a house of loggers. After I came down I'm like, "Stomach....expanding...ripping...can't...take it...!!" I knew if I didn't puke, I was gonna definitely have a major ass stomach ache (I have an extremely sensitive stomach to certain foods, the foods I usually eat when I'm stoned, haaaa) so I went to the bathroom, used a couple cotton swabs to gag myself, and puked up everything I had eaten.

Afterwards....was not good. My head hurt like a BITCH because I puked really hard.

Anyway, as I said in another topic, this girl I know pukes almost every time she comes down because she feels really sick and light headed and stuff. So, maybe your friends just has that....except...when he's stoned. ^_^

To s2headhunter, I don't think so. Personally, I think gravity bongs fuck me up a LOT more than hot knifing. It uses more weed in comparison, but my high is MUCH more intense and lasts longer.

It could just be that I haven't perfected the technique, but ya know...
