Personally I have never puked from being stoned alone... However, recently I've been gettin stoned with an old friend, and twice he threw up. The first time we just smoked one joint between us. And he was complaining about him feelin sick, so I parked up and let him relax. We were just sat there quite for a while, until he decided it was time to go home as he wasn't feeling to well. So I drove to his house, parked up outside, and suddenly he told me to carry on going forward... So I carried on say 50 metres or so and parked up. I looked at him and he just had his head down... then suddenly he open the door n chucked up, so i told him to get back in and took him to a petrol station n bought him a bottle of pepsi. Then, a few days later, we got stoned again. This time we shared the first joint, and as soon as that was over we hopped back in the car and I rolled another. We both jumped out again and smoked that... Then he said he was hungry, so I took him to a takeaway, where he bought a burger. Then we went and parked up somewhere, and again he sat there with his head down. He made me turn of the radio, he asked me not to talk to him (so i just rolled another joint and hopped out again ) so I sat there waiting. He just left his burger on the dashboard, he hadnt touched it. And within about 30 minutes he jumped out and threw up again... Was really annoying!

From both those times though, I noticed that each time we smoked, then I drove us for at least 5 minutes, and then his high went downhill. I'm guessing he was just gettin car sick both times because of being stoned... Oh well, I haven't got stoned with him for about a week now, then again I'm on a break so...
