Psychotropic drugs in developmental mushrooms: a case study review.

Psilocyn and psilocybin can be identified in different stages of developing psilocybe mushrooms. Knowing the various stages of the mushroom development can be useful when receiving evidence from illicit mushroom growing operations. Exhibits from three separate cases were submitted to the drug analysis section of the Minnesota Bureau of Criminal Apprehension Forensic Science Laboratory. Each case contained different stages of developing mushrooms. This report describes the evidence in each case, the sample preparation, the sample analysis and the final report that was written.
