Unfortunately, its a true story. I also have been at it since the 70’s.There is a lot of info on the link posted above. Cannabinoid hyperemesis syndrome or CHS I can tell you It occurred after I started growing my own. The potency of my grow (with the help of this forum ) Is the best I had ever had. After about 2 years of a greatly increased usage, many times a day, It hit me. I have a great supply. Not buying it off the street, and it is always there for me, hence the increase in usage. Now I have to really watch it. A few times a week or it creeps back in. It definitely does not effect everyone. I have a friend who smokes the same stuff even more frequently and he’s really high and happy. The point here is if you are one of the few, hopefully what is here in the forum will help you identify it and work with it. I firmly believe for me it is the high potency of good weed that triggered it. As the link indicates, a few of the best on the forum are aware of it. Make no mistake it is real. Not a heart attack. No pain, just a whole lot of puking and nausea for days.
