About this study

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.
