> Is there a test you can take to rule out long-term negative side effects from psychedelics? PiHKAL and TiHKAL reports start with "allergy tests" of low doses around 1/10th of a typical dose. Erowid and other resources (Psychonaut wiki, etc.) list a starting dose of LSD to be around 25mcg, while the author here took 160mcg as a virgin- over 5x the starting dose. It's also not clear whether they tested the drugs, which likely means they did not. The report sounds more typical of a DO(x) or NBOMe substance than LSD, which also come on blotters and are sold as LSD relatively frequently.
