Toxic by design? Formation of thermal degradants and cyanide from carboxamide-type synthetic cannabinoids CUMYL-PICA, 5F-CUMYL-PICA, AMB-FUBINACA, MDMB-FUBINACA, NNEI, and MN-18 during exposure to high temperatures.

ABSTRACT:

Purpose

The use of novel synthetic cannabinoids as intoxicants continues in spite of associated health risks. These compounds are typically smoked or vaporized, but many synthetic cannabinoids contain thermally labile chemical moieties. This study investigated the thermal stability six carboxamide-type synthetic cannabinoids (CUMYL-PICA, 5F-CUMYL-PICA, AMB-FUBINACA, MDMB-FUBINACA, NNEI, and MN-18) in order to characterise potential user exposure to thermolysis products.

Methods

Compounds were heated sequentially to 200, 400, 600 and 800 °C using a thermolysis probe, and the resultant thermolysis products were analysed via GC-MS. A secondary analysis quantified thermolytically generated cyanide via LC-MS/MS.

Results

All six synthetic cannabinoids underwent thermal degr
