PK/PD dello svapo di liquidi contenenti THC rispetto alla cannabis affumicata
Uno studio cross-over randomizzato all'interno del soggetto per confrontare gli effetti PK/PD a breve termine dello svapo di liquidi contenenti THC rispetto alla cannabis affumicata
We will conduct a randomized, within-subjects clinical study to compare short-term pharmacokinetic (PK) and pharmacodynamic (PD) effects of Δ9-tetrahydrocannabinol (THC) vaping liquids vs. smoked cannabis containing 6 equivalent standard THC units (5 mg THC=1 Standard THC Unit (STU)) in healthy community members who are current users of both products. While smoking cannabis remains the most common mode of THC use among adults and youth, alternative modes of delivery, such as Electronic Vaping Products (EVPs), are becoming increasingly popular for the delivery of cannabinoids. Declining cannabis risk perceptions, increasing normalization of cannabis, greater legal access and availability to cannabis, ease of administration, and ability to conceal vaped THC use have likely contributed to increasing prevalence of use throughout the population across all age groups. Comparing vaping THC containing liquids with smoking cannabis can serve as an important benchmark for evaluating the delivery and effects of THC vaping products and, their relative safety

Peak Plasma Concentration (Cmax)
Lasso di tempo: From baseline to 360 minutes after consuming product

Blood samples will be collected for plasma levels of THC. All individual pharmacokinetic (PK) parameters will be derived from plasma THC concentrations-versus-time data by non-compartmental analysis using Phoenix WinNonlin, corrected for baseline THC concentrations. Mean differences for each measure will be compared between the experimental (THC vaping) and active control (smoked cannabis) conditions, and by sex |
