Yeah, I watched a documentary where they followed some people to these retreats. One of them had an awful reaction and had to go to the hospital. She said it really messed her up.
I guess, like anything, it could affect people differently.
For example, I always have friends talk about how much marijuana reduces their anxiety and stress and makes life more manageable. For me, it sends me into the worst panic attacks and depersonalization you could ever imagine. I won’t go anywhere near it. 2 of the worst experiences of my life on it. For others, though, it seems to do the opposite. (Even at lower doses it increases my anxiety and heart rate, at higher doses it’s a living nightmare)
