PHASE1

PK/PD of Vaping THC-containing Liquids vs. Smoked Cannabis

Sponsor: Roswell Park Cancer Institute

View on ClinicalTrials.gov

Summary

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
