Three new LSD-like designer drugs were identified in paper sheet products seized in Japan between September 2019 and March 2020. Using methanol extraction followed by LC-MS, high-resolution MS, GC-MS, and NMR analyses, the compounds were identified as 1cP-LSD, MIPLA, and 1B-LSD. Like other N1-acylated LSD derivatives, 1cP-LSD and 1B-LSD easily break down into LSD during GC-MS analysis, requiring caution when testing.

From 2014 to 2017 in Japan, four lysergic acid diethylamide (LSD) derivatives were detected in paper sheet products sold as designer drugs. The compounds were identified as ALD-52, ETH-LAD, AL-LAD, and 1P-LSD using GC-MS, LC-MS, LC-Q-TOF-MS, and NMR analyses. Extraction methods and analytical conditions for GC-MS, LC-MS, and LC-FL were studied. As of September 2019, 2372 substances and two plants are controlled as "Designated Substances" under Japanese law. Only 1P-LSD was already regulated since April 2016; pharmacological evaluation of the other derivatives is ongoing to inform future legislation.

Three new derivatives of the dissociative drug methoxetamine (MXE) were identified in illegal products in Japan: methoxpropamine (MXPr), methoxisopropamine (MXiPr), and deoxymethoxetamine (DMXE). MXE itself, an analog of the anesthetic ketamine, is already controlled as a narcotic in Japan, and its overdoses have caused health problems. All arylcyclohexylamines, including these new substances, act as antagonists of the NMDA receptor. The findings highlight the ongoing emergence of novel psychoactive substances designed to evade legal controls.
