Effects of daily administration of saline (upper left), 30 mg/kg Δ9-THC (upper right), 3 mg/kg JWH-018 (bottom left) or 10 mg/kg JWH-073 (bottom right) on core temperature in mice (n=5 per group). Only data from days 1 (black circles) and 5 (grey squares), and after 14 days of cannabinoid abstinence (inverted triangles) are shown. Abscissa: time after drug injection, in minutes. Ordinate: core temperature, in °C, as measured via radiotelemetry. Absence of error bars indicates an instance where the variability is contained within the point. For statistical comparisons, please see section 3.2.
