Brief Summary
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.

Pending legal action or other reason that, in the opinion of the study physician, might prevent study completion; 11. Use of medication within 7 days of experimental sessions; which, in the opinion of the Investigator, may interact with cannabis. 12. Participation in clinical studies or undergoing other investigational procedure involving cannabis or cannabinoids administration within 30 days prior to randomization. 13.
