“Alternate injections of epinephrine (2 micrograms/kg) with vehicle and increasing cannabinoid doses (1.25-5.0 mg/kg) indicated a potentiation of both the duration of the pressor effect and the magnitude of the reflex bradycardic effect of epinephrine by both delta 9- and delta 9(11)-THC.”
“ Epinephrine also produced arrhythmias in rats receiving cannabinoids , but not in rats receiving alternate injections of vehicle.”
