I've never barfed myself after tokin, but I did witness a new comer barf back when I was 15. I'm not sure why he did, but this guy was a real showboat kind of guy, so he was taking massive hits to seem badass. He ended up barfing in front of all the girls.

Wait, I did barf once after tokin, but it wasn't right after. I got off work at midnight and I toked a bowl on the way home, about a 30 minute walk. I got home, watched some TV, then I got sick to stomach.

In the end, I don't think it was the weed. Maybe something I ate? Who knows, but I wouldn't be too worried about it unless it keeps happening.
