"Consistent with results from nonhuman animal research (Mowry et al.,2003), the present results suggest a safe physiological profile for salvinorin A at the studied doses, under controlled conditions, and in psychologically and physically healthy hallucinogen-experienced participants. Salvinorin A produced no significant changes in heart rate or blood pressure; no tremor was observed; and no adverse events were reported. Participants tolerated all doses. However, because of the small sample and the healthy, hallucinogen-experienced status of participants, conclusions regarding safety are limited."
