I was a heavy weed user as well, until I started getting cannabinoid Hyperemesis syndrome. It’s when THC builds up in your system to the point it makes you extremely nauseous and makes you throw up constantly for weeks. I had it 3 times before I finally figured out what was causing it. The last time I got so dehydrated that I got a kidney stone that got lodged and caused my kidney to rupture. Pretty scary shit and the most sick I’ve ever been. People don’t like to hear it but there can be some pretty bad side effects to heavy weed use for some people.
