From November 2013 to May 2014, 19 newly distributed designer drugs were identified in 104 products in our ongoing survey of illegal products in Japan. The identified compounds included 8 synthetic cannabinoids, FUB-PB-22 (1), 5-fluoro-NNEI indazole analog (5-fluoro-MN-18, 2), AM-2201 indazole analog (THJ-2201, 3), XLR-12 (4), 5-fluoro-AB-PINACA (5), 5-chloro-AB-PINACA (6), AB-CHMINACA (7), and 5-fluoro-AMB (8); 5 cathinone derivatives, DL-4662 (9), α-PHP (10), 4-methoxy-α-POP (11), 4-methoxy-α-PHPP (12), and 4-fluoro-α-PHPP (13); and 6 other substances, namely, the benzofuran derivative 2-(2-ethylaminopropyl)benzofuran (2-EAPB, 14), nitracaine (15), diclofensine (16), diphenidine (17), 1-benzylpiperidine (18), and acetylfentanyl (19). To our knowledge, this is the first report on the chemical properties of compounds 9–11 and 14. A total of 33 designer drugs, including compounds 1–19, were detected in the 104 illegal products, in 60 different combination patterns. The numbers of detected compounds per product ranged from 1 to 7. In addition, several products contained three different types of compounds, such as synthetic cannabinoids, cathinone derivatives, and phenethylamine derivatives per product. It is apparent that the types of compounds emerging as illegal products are becoming more diverse, as are their combinations.
