I'm a very experienced cannabis user I've been smoking on the daily for almost 4 years. I've thrown up a few times from fat bong rips because of pulling it into my lungs too quickly messing up my stomach. But the other day I was with a friend and we smoked one king size joint which is just a warm up usually. About 30 minutes after the joint was finished I started to feel very nauseous and I started to get hot flashes and was sweating like crazy. I stud up to go in the house and get some water but as soon as I stood up I started to retch and threw up shortly after. Anybody know why this happens?
