Cannabis intoxication after accidental ingestion in infants: urine and plasma concentrations of Δ-9-tetrahydrocannabinol (THC), THC-COOH and 11-OH-THC in 10 patients.

Accidental cannabis poisoning after oral ingestion in infants is an emerging cause of intoxication with well-known clinical aspects but few data exist regarding the levels of cannabinoids in plasma and urine. Here, we present data on the concentrations of Δ-9-tetrahydrocannabinol (THC) and metabolites in plasma and/or urine in 10 infants after cannabis intoxication. Cannabinoids were detected using an automated immunochemical method and quantified using liquid chromatography coupled with mass spectrometry.
