Ok, this is something im really confused about. Recently, i met a dude who smokes every once and a while and i finally got to smoke with him the other night. We got a bowl and some weed and smoked for an hour. Later into the night, he got a trashcan and i was like "Whats that for?" And he told me that EVERY time he smokes, he throws up and passes out. I kinda thought he was joking because he was high. Well, at about 1 when it was time to go to sleep, i heard him throwing up REALLY hard. I was very suprised and was curious of why he did, im hoping one of you could help me out here. By the way, he didnt eat much so i doubt it was just food consumption.
