Frequency and duration of nosing and anogenital sniffing with a standard opponent A/JArc mouse after injection with CBD (1, 50 or 100 mg/kg). Data represent means (± S.E.M.). Significant one-way ANOVA (split by corresponding factor) results are shown:

^* P<0.05 (vs. WT receiving corresponding treatment);

^## P<0.01 (vs. vehicle of corresponding genotype).
