Mean number (±SEM) of gapes at test elicited by 0.1% saccharin solution previously paired with each compound during the drug-free test trial. Numbers in parentheses indicate n per group. *P < 0.05; ***P < 0.001 from other groups indicated by line [10 mg·kg⁻¹ THCV, 20 mg·kg⁻¹ THCV, 10 mg·kg⁻¹ CBDV, 200 mg·kg⁻¹ CBDV and VEH, which did not differ from one another (ns)]. Those conditioned with 10 mg·kg⁻¹ SR, 20 mg·kg⁻¹ SR and AM251 did not significantly differ from one another, although there was a trend for 20 mg·kg⁻¹ SR to display more gaping than 10 mg·kg⁻¹ SR (P = 0.07).
