Perceptions about THC and CBD effects among adults with and without prior cannabis experience.

Background: Cannabis is associated with a range of therapeutic and non-therapeutic, positive and negative effects. While some benefits and harms may be specific to individual cannabinoid constituents (THC, CBD), individual expectancies may also play a role.

Objectives: Evaluate the extent to which individuals hold expectancies about the effects of CBD, THC, and THC & CBD combined, and whether this differs with prior cannabis experience.
