Free and Glucuronide Whole Blood Cannabinoids' Pharmacokinetics after Controlled Smoked, Vaporized, and Oral Cannabis Administration in Frequent and Occasional Cannabis Users: Identification of Recent Cannabis Intake
Key Findings: Cannabigerol (CBG) and cannabinol (CBN) were similarly detectible in samples of both occasional and frequent cannabis users who consumed smoked or vaporized products and represent recent consumption better than THC levels. Oral consumption produced much higher 11-nor-9-carboxy-THC (THCCOOH) and THCCOOH-glucuronide levels.
