I have talked to some caregivers that make edibles and one lady got pretty nauseated but nothing that hung on permanently. I have been hearing more about THC poisoning and I agree with a previous post that maybe something was wrong with your pot. Maybe mold or a pest infected it. I had also heard about medical marijuana having negative affects on people who are on anti-psychotic meds. Marijuana will enhance any predetermined illness, known about or not. I hope you find the answer to your problem cuz that really sucks
