<p>To prevent the abuse of new psychoactive substances (NPS), a total of 2372 substances and two plants are controlled as “Designated Substances” in Japan as of September 2019. Although the distribution of these substances has decreased for the past three years, newly-emerged NPS are still being found. In this study, we detected four lysergic acid diethylamide (LSD) derivatives as designer drugs from four paper sheet products, which were obtained from 2014 to 2017 in Japan. The compounds were identified as 4-Acetyl-N,N-diethyl-7-methyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (ALD-52), N,N,7-triethyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (ETH-LAD), 7-Allyl-N,N-diethyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (AL-LAD), N,N-diethyl-7-methyl-4-propionyl-4,6,6a,7,8,9-hexahydroindolo[4,3-fg]quinoline-9-carboxamide (1P-LSD), by GC-MS, LC-MS, LC-Q-TOF-MS and NMR analyses. Further, we studied the extraction methods of LSD derivatives from paper sheet, and the analytical conditions of GC-MS, LC-MS and LC-FL(fluorescence). Among LSD derivatives, 1P-LSD have been controlled as designated substances (Shitei Yakubutsu) under the Pharmaceutical and Medical Device Act in Japan since April 2016. For the legislation of the other derivatives identified in this study, the evaluation of their pharmacological properties are now in progress.</p>
