Introduction: Lysergic acid diethylamide (LSD, lysergide) is known as one of the most powerful hallucinogenic drugs of abuse. LSD was explosively abused in . in the latter half of the 1960s. In Japan, the amount of seizure of LSD is much smaller than that of methamphetamine. However, in recent years, it has been increasing markedly; 3,500 tablets of LSD were seized in 1996, while 53,043 tablets in 2000 (about 15-fold increase), arousing a serious concern about the phenomenon. LSD is a compound chemically modified from ergot alkaloid produced by a bacterium Claviceps purpurea. LSD is one of the compounds synthesized. | Lysergic acid diethylamide LSD by Shinichi Suzuki Introduction Lysergic acid diethylamide LSD lysergide is known as one of the most powerful hallucinogenic drugs of abuse. LSD was explosively abused in . in the latter half of the 1960s. In Japan the amount of seizure of LSD is much smaller than that of methamphetamine. However in recent years it has been increasing markedly 3 500 tablets of LSD were seized in 1996 while 53 043 tablets in 2000 about 15-fold increase arousing a serious concern about the phenomenon. LSD is a compound chemically modified from ergot alkaloid produced by a bacterium Claviceps purpurea. LSD is one of the compounds synthesized by the reactions of lysergic acid isolated from the ergot with various amines at the Rockefeller Institute in the 1930s LSD was synthesized as the 25th compound and thus called LSD-25. The strong hallucinogenic activity of LSD was confirmed by Albert Hofmann who did synthesize the compound the pharmacological activity can be obtained by oral administration of as small as 20-75 pg of LSD. The absorption of LSD from the digestive tract is rapid and distinct visual hallucination takes place 45 min-1 h after oral intake of about 20 pg of LSD 1 . The hallucination becomes most marked 2-3 h after the intake and lasts for 8-12 h. In this chapter a detection method by TLC and confirmatory analysis by GC MS for LSD are presented. Reagents and their preparation LSD can be obtained from each local bureau of drug enforcement officers under an official transfer process. p-Dimethylbenzaldehyde reagent a aliquot of p-dimethylaminobenzaldehyde Wako Pure Chemical Industries Ltd.
