The selective cannabinoid CB1 receptor antagonist SR141716 has been shown to precipitate physical signs of withdrawal in ∆9-tetrahydrocannabinol (THC)-dependent rats; however, the affective state associated with this withdrawal state has not yet been well characterized. Thus, the aim of present study was to examine the physical and affective consequences of SR141716-precipitated THC withdrawal in male Sprague-Dawley rats. Rats were injected with THC (5 mg/kg, i.p.) or its vehicle twice daily for 13 consecutive days, and challenged with SRI 41716 (1 mg/kg, i.p.) or its vehicle 1 h later on days 3, 5, 7, 9, 11, and 13.
