>Current tests suggest it is not likely related to any other known psychedelic compound. For one, the trips it produces are unusually long, commonly lasting 12 to 24 hours, and in some cases even causing hospital stays of up to a week.

Plenty of common psychedelics have durations in excess of 12 hours. Some even in excess of 24 e.g. high doses of 2C-P. This may be a novel compound, but the duration is not necessarily an indicator.

I read this merely as not likely corresponding to any psychedelic compound known to occur in nature, not that it isn't psychedelic. Of course, even that isn't a given, since there could be some interaction between a known compound and a second compound affecting the metabolism of the first one. Although the description of its effects doesn't really sound like any psychedelic I've tried either, and I've tried quite a few

I'm still open to it being psychedelic(primarily acting on the 5-HT-2 receptor family) though. It could just be that there's enough folklore surrounding these mushrooms in the local culture to explain the very specific effects. After all, cultural beliefs are a part of "set and setting".

Another example, this one deliriant and not psychedelic, is atropine/scopolamine, found in certain nightshades, such as deadly nightshade, mandrake, plants in the Datura genus, and trees in the Brugmansia genus. The chemical weapon QNB, also called BZ is another example of a long-acting deliriant.

As far as classic psychedelics go, I've read mescaline (3,4,5-trimethoxyphenethylamine) lasts really long.

My experiences with mescaline are that it has mostly wound down by 6-8 hours though I can tell that I am slightly "off" for a few hours after that. Shorter timeframe than LSD, though not by a whole lot.

Young me was always interested in trying datura despite the harrowing trip reports on erowid. Glad i never was presented with the opportunity.

I tried it during the summer between 8th and 9th grade after discovering a Datura Stramonium plant growing at a beach on Cape Cod. Fortunately the plant was growing in sand, and the alkaloid content of the plant was very low. I boiled an entire pod down in a soda can and gave it a try. In terms of effects, I did not become delirious, but my perception of gravity was greatly enhanced; I felt like I weighed 600lb. My eyes were also completely incapable of focusing on anything close-up for several days. I never tried Datura again, and I never will. I was lucky I didn't wind up dead, in jail, or in the hospital.
