Well the first person that had the bad experience with it was my ex-girlfriend, who suffered a two month long psychotic episode which had to be treated with anti-psychotics. Then it was me, I took four tabs and had spiraling thoughts, I felt I was insane, I couldn't communicate with my body and then I couldn't even communicate with myself, heart raced - I felt I was dying. This lasted for 4 hours, afterwards it was hard forming sentences or thoughts, going to sleep, or functioning normally. Then one of my friends took five tabs and he went insane in public, took his pants off and started running around, hitting people, and was completely non-responsive. We have all done high doses of LSD before, but it seems a little too much to call them all coincidences. The episode of my ex can be explained a little bit by her past, but me and my friend's experience really can't. It was acid on blotter, no real taste, no drawing (no acid over here ever has drawings.) I would say 1x1cm.
