Analysis of psilocin, bufotenine and LSD in hair.

abstract：:Clonazepam, nitrazepam and flunitrazepam are frequently used benzodiazepines, both as prescribed medication and as drugs of abuse. Little is, however, known about how these drugs are excreted in oral fluid. It has been claimed that the parent drugs are more likely to be detected in oral fluid than the 7-amino metaboli...
