>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.
