[195] [187] Findings also conflict on whether psilocybin can be detected in urine, with either no psilocybin excreted or 3% to 10% excreted as unchanged psilocybin. [ 197 ] [ 2 ] [ 15 ] [ 7 ] [ 19 ] A majority of psilocybin and its metabolites is excreted within three hours with oral administration and elimination is almost complete within 24 ...
Their 1963 publication was the first report of psilocybin in a European mushroom species; previously, it had been known only in Psilocybe species native to Mexico, Asia and North America. [33] This finding was confirmed in the late 1960s with specimens from Scotland and England, [ 54 ] [ 55 ] Czechoslovakia (1973), [ 56 ] Germany (1977), [ 57 ...

Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae.Known from central Mexico, Arizona, California, Oregon, Colorado, Canada, Costa Rica [citation needed], and possibly India, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of 2,000 to 4,000 m (6,600 to 13,100 ft), typically in meadows or open, grassy conifer forests.
Testing done on 33 samples purchased at smoke shops in Los Angeles and San Diego counties found 40% contained no psilocybin — one of the main chemicals that make mushrooms magical.
Yet local dispensary owners and employees are frequently busted for selling mushrooms, psilocybin products and other illicit substances. In April 2022, the L.A. County Sheriff’s Department ...
