The Pharmacokinetics and Pharmacodynamics of Hemp-based Topical Cannabinoid Products Identifier: NCT04741477

Brief Summary:

This study will evaluate the pharmacokinetic and pharmacodynamic effects of hemp-based Cannabidiol (CBD) topical products (e.g., lotions, creams, patches) that contain low levels of delta-9-tetrahydrocannabinol (THC).

Detailed Description:

A total of 5 topical cannabinoid products will be examined in this study. The study will be conducted in 5 discrete stages, one for each product. In each stage, participants (N=20), will be randomized to 1 of 2 double-blind drug conditions that entail the use of: 1) a topical product that contains CBD and a low amount of THC (N=15), or 2) a placebo topical product that does not contain cannabinoids (N=5), but which contains similar non-cannabinoid ingredients to the active product. Thus, overall 100 participants will complete the study (75 active, 25 placebo).

Participants in each stage will complete a three-phase outpatient protocol that will last a total of 17 days. Phase 1 (Day 1) will be an acute laboratory dosing session (approximately 7 hours in duration). Phase 2 (Days 2-10) will be an outpatient dosing period, during which participants will continue to use participants' assigned product twice daily (morning and evening) in participants' own environment. During Phase 2, participants will visit the laboratory for brief study sessions on Days 2, 3, 7, and 10. Phase 3, will consist of a final follow-up visit on Day 17, after a 1-week drug washout. Pharmacokinetic and pharmacodynamic assessments (subjective and cognitive effects) will be assessed during each phase.
