Identification and Analysis of Lysergic Acid Diethylamide Analogs, 4‐Benzoyl‐ N,N ‐Diethyl‐7‐Methyl‐4,6,6a,7,8,9‐Hexahydroindolo[4,3‐ fg ]quinoline‐9‐Carboxamide (1Bz‐LSD) and N , N ‐Diethyl‐7‐Methyl‐4‐(4‐(Trimethylsilyl)Benzoyl)‐4,6,6a,7,8,9‐Hexahydroindolo[4,3‐ fg ]quinoline‐9‐Carboxamide (1‐TMSBz‐LSD), in tablet or paper sheet products available online in Japan
Drug Testing and Analysis February 18, 2026 Rie Tanaka, Maiko Kawamura, Michiho Ito et al.
Recently, many lysergic acid diethylamide (LSD) analogs have emerged as designer drugs worldwide. In Japan, these compounds are distributed as paper sheet or tablet products and are available online. Even after these compounds were regulated, new compounds with modified structures continued to appear. In the present study, two LSD analogs were identified from tablet or paper sheet products.
