Effects of oral Δ9-tetrahydrocannabinol and cannabidiol combinations on a sustained attention task in rats.

ABSTRACT: A well-documented side effect of cannabis and Δ9-tetrahydrocannabinol (THC) acute administration is deficits in cognition and attention. Cannabidiol (CBD), a nonintoxicating constituent of cannabis, may modulate THC's impairing effects. A goal of this study was to determine the effects of THC and CBD, alone and in combination, on performance in the rodent Psychomotor Vigilance Test (rPVT), a translational paradigm used to quantify sustained attention. Outcome measures in the rPVT include motor speed, premature responding, and lapses in attention. Sprague Dawley rats were trained to perform the rPVT to the acquisition criteria and then received oral doses (mg/kg) of THC (1-17.6), CBD (1-100), and combinations of THC + CBD in sesame oil prior to rPVT sessions, administered in a within-subjec
