So I was a daily smoker and then I would take a rip, and immediately throw up. It would subside after a few hours and I was good for the rest of the day, but I thought it was weird so I stopped smoking for a couple of months, and figured I'd be OK smoking again this weekend. I took 2 hits, and immediately needed to throw up. They weren'tmonster hits nor did I get enough to even make me cough, but as soon as I took the second hit, I had to expell everything. Can someone please give me clarification on what is possibly going on?
It is most likely this. OP is one of the unfortunate people that just cannot use marijuana safely due to his biology. If you have cannabinoid hyperemesis, best to stay away from weed because the constant nausea/vomiting can lead to unintentional weight loss and a lot of other physical problems that are no fun.
