2026年9月2日 更新者:Johns Hopkins University
The Pharmacokinetics of a Hemp-Based Topical Cannabinoid Product in a Sanitized and Controlled Environment
This study will evaluate the pharmacokinetic effects of acute and chronic dosing of a hemp-based cannabidiol (CBD) topical lotion with low levels of delta-9-tetrahydrocannabinol (THC) in a sanitized and controlled environment.
研究概览
详细说明
Participants (N = 6) will complete an 7-day residential study using a high CBD/low D9-THC lotion.
The lotion is applied to the participants' upper arms four times daily in a sanitized and controlled procedure that eliminates the potential for specimen contamination.
Oral fluid (OF) is collected before and after application (six samples/day); blood and urine are collected once/day.
On discharge day, participants provide an intentionally contaminated OF sample.
Participants return after a 7-day washout to provide 4 additional OF specimens, one "clean" and three more intentionally contaminated samples over a two-hour course.
