yeah I was thinking along the lines of living things, I am aware that there are a few gases and solvents that can be utilized(although most of the solvents are quite simply retarded) I have a friend who supposedly had his first entheogenic experience with Fugu. I have also heard of a fish called Sarpa Salpa(dream fish) but it seems to be quite dangerous and unpleasant with hallucinations lasting days. just wondering if anyone was aware of any others.
