Blotter papers have traditionally been abused with LSD, but new psychedelic phenethylamines like 2C drugs and their N-benzylhydroxy (25-NBOH) and N-2-methoxybenzyl (25-NBOMe) derivatives now appear in the illicit market. GC-MS, the standard for drug analysis, fails for thermally labile 25-NBOH drugs because they degrade into 2C drugs during analysis. A non-thermal LC-MS/MS method was developed and validated to simultaneously identify twelve phenethylamines, their derivatives, and LSD without thermal degradation. The method was applied to seized blotter papers and Ecstasy tablets.
