An increasingly common reaction to CBD and THC. Cannabinoid Hyper emesis Syndrome. I personally know at least half a dozen people other than myself who’ve been diagnosed. It’s 10% of abdominal issues in Denver ERs. Once it triggers, you can’t touch THC or CBD for the rest of your life or you’ll inevitably end up back in the ER. You get it from using THC more than 3 days a week, especially the high dose stuff. It makes you violently throw up about every 20 minutes and it can last for days. Even when it stops, you can’t eat normally for weeks and have several “trigger foods” you have to avoid for months or years (including caffeine and alcohol). I almost went into cardiac arrest from low potassium and I have kidney damage from my last event. I will NEVER smoke again. My friends 18 year old was diagnosed last year. So was a co-workers husband. I know lots of people. It’s the most horrible thing I’ve ever experienced. People need to know.
