Effects of 18-MC (20 mg/kg i.p.) on food intake in rats assessed in food monitor chambers: a mean intake of chow (in grams), b average number of bouts, and c average bout size (in grams). Each data point represents the mean values for 23 h (±SEM) of rats having access to water, sucrose, and chow and treated with 18-MC (n=5) or vehicle (n=6). Arrows indicate the beginning and the end of treatment with 18-MC. *p<0.05, significant difference between drug vs. vehicle, Fisher LSD tests
