True story, late 1970s a bunch of us were camping and buddy drops a hit of purple microdot…not feeling it after about an hour so he drops another…an hour later he vanishes. Nothing we can do as access to our camp is by water only, it’s pitch black, and we’re in the bush…bear, deer, moose, etc. Buddy stumbles out of the woods after daylight…he’d spent 10 hours hugging a tree, on 2 hits of cid. He never did acid again.
