Effects of THC on percentage of responses that occurred on the THC-associated lever (top panel) and response rate (bottom panel) in female (filled circles) and male (filled squares) Sprague-Dawley rats trained to discriminate 1.7 mg/kg THC from vehicle in a lever procedure. Control tests with vehicle (V) and 1.7 mg/kg THC (T) are shown at the left side of the panels. Each point represents the mean (± SEM) of data for 8 rats, except for %THC aperture responding for 3 mg/kg THC (males, n=7). Data for %THC aperture responding at 3 mg/kg THC for 1 male rat were excluded due to fewer than 10 overall responses. Pound sign (#) indicates a significant main effect for dose across both sexes (p<0.05) compared to vehicle (at left side of each panel).
