There are a couple of things you can do. First, make sure that you're well hydrated before you smoke. Dehydration can exacerbate nausea, and smoking is dehydrating. So is summertime heat!

I've always found that one of the best all-purpose anti-nausea meds around is Dramamine (generic name dimenhydrinate). It's marketed as an anti-motion sickness drug, but it's a very effective anti-nausea medicine and is sold over the counter. Half of a tablet usually does the trick for me. It's a first cousin to Benadryl/diphenhydramine. You can take it with other meds (like cannabis) or on its own. It's famous for causing drowsiness/sleepiness, but for me it works like a charm to quell nausea.
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
