Abstract
We tested the hypothesis that THC disrupts self-timed actions in healthy volunteers, and that this effect is related to self-rated perceptions of time distortion. We found that THC impaired subjective time perception and reduced the rate of button pressing, although the change in the rate of button pressing was more closely related to impaired concentration and intoxication. We conclude that THC-induced disruption of self-timed actions may arise from a different mechanism to alterations in time perception.
