Cannabinoid tetrad tests: (A) locomotion, (B) rectal temperature, (C) catalepsy and (D) tail immersion. Data expressed as mean ± SD. When a P-value is less than 0.05, a star on the graph denotes statistical significance. Locomotion (n = 4; df = 2; chi-square = 7.446); rectal temperature (n = 4; df = 2; chi-square = (0.746, 8.405); catalepsy (n = 3; df = 2; chi-square = 6.006); tail immersion (n = 4; df = 2; chi-square = 8.200)
