RE: Cannabis Hyperemesis Syndrome(CHS) is Azadirachtin Poisoning (@tralawar's post reminded me to post this. Ty tralawar)
Anti-Histamine use temporarily relieves some of the symptoms.... The last attack I had I used benadryl and it helped IMMENSELY with all of the symptoms.
This means it's an allergic reaction. Activated charcoal pills help remove the azadirachtin from your body. Start with 1 a day and max out at 2 a day, because too much charcoal is not good at all. heh
