Modulation of THC Effects by CBD: a Dose-ranging Study (NCT06099379)
Modulation of ∆9-tetrahydrocannabinol Acute Psychoactive Effects by Ranging Doses of Cannabidiol in Healthy, Occasional Cannabis Users: a Controlled, Triple Blind, Randomized, Cross-over Study
🩺 Plain-English Summary (8th-Grade Level)
The purposes of this study are 1) to determine if CBD modulates THC-induced acute psychoactive effects at different CBD:THC ratios, compared with the control product (0:20, 20:20, 40:20, 80:20, 120:20) and 2) to determine if different doses of CBD modulate other THC induced behavioral effects, compared with the control product and 3)To explore qualitatively whether CBD modulates THC effects by mechanisms that are not detected with standard clinical research tools.
