Wow! I was going to have to go looking for that thread TheMetal1 quoted above or else rewrite it. That came in handy, TheMetal! Thanks.

Yep, it just seems like for a very small fraction of people, the nausea/vomiting centers of the brain get stimulated instead of subdued by cannabis. I also think sometimes a very dramatic vomiting response may have more to do with anxiety--panic and an adrenaline surge frequently spur vomiting, too--or even a response to coughing from the harshness of the smoke.
birdgirl73 Reviewed by birdgirl73 on . Why do people puke or get nausea from weed? If grass is supposed to suppress nausea and such why do I frequently hear of people who have "smoked too much" and ended up violently puking or feeling really nauseous until their high came down? It just doesn't add up to me; any clarifying? And how can you stop this? Rating: 5
