Abstract

Medical and recreational cannabis legalization has highlighted the importance of being able to identify recent cannabis use and impairment. Monitoring minor plant cannabinoids has been proposed to assist in identifying recent cannabis use. Additionally, cannabidiol (CBD) has been proposed for epilepsy, pain, inflammatory disorder, anxiety, and addiction treatment; therefore, monitoring CBD is of increasing clinical importance. However, few methods exist capable of monitoring extensive panels of traditional cannabinoid analytes and minor cannabinoids (including CBD). This chapter details a liquid chromatography tandem mass spectrometry method capable of measuring Δ9-tetrahydrocannabinol (THC), 11-hydroxy-THC, 11-nor-9-carboxy-THC, cannabinol, cannabigerol, tetrahydrocannabivarin (THCV), and its metabolite, 11-nor-9-carboxy-THCV, in urine.
