Prevalence of carboxy ‐Δ8‐tetrahydrocannabiniol in antidoping samples

This study aims to estimate the prevalence of Δ8-THC use in the athlete community by monitoring for Δ8-THC-COOH in samples collected for antidoping. A high-performance liquid chromatography tandem mass spectrometry (LC –MS/MS) method was utilized to resolve Δ8 and Δ9-THC-COOH. One thousand samples with a presumptive Δ9-THC-COOH finding in routine screening were analyzed by the above LC –MS/MS method. Approximately 12% of samples contained Δ8-THC-COOH at relative abundances between 5% and 100% of total carboxy-THC content.
