Salvinorin A has been reported to be the most potent naturally occurring hallucinogen, with an effective dose in humans in the 200- to the 1,000-μg range when smoked; it has been reported to induce an intense hallucinatory experience in humans, with a typical duration of action being several minutes to an hour or so. Salvinorin A is a highly selective agonist of the kappa-opioid receptor (KOR) with few off-target effects. It is a potent and selective dilator of the cerebral vasculature, exhibits rapid penetration through the blood-brain barrier, has potent anti-inflammatory properties, and has the ability to preserve neurovascular unit integrity. As such, salvinorin A is an ideal compound for the prevention and treatment of cerebral vasospasm following subarachnoid hemorrhage.

To identify Salvinorin A's molecular target, it was screened Salvinorin A (10 μM) at a large panel of mainly cloned human G protein-coupled receptors (GPCRs), transporters, and ligand-gated ion channels by using the resources of the NIMH-PDSP. For comparison, it was screened the same molecular targets with the prototypic hallucinogen LSD, also at 10 μM. Salvinorin A inhibited only [3H]-bremazocine-labeled κ opioid receptor (KOR) KORs and did not significantly inhibit binding to cloned human μ (MOR) or δ opioid (DOR) receptors or any of the 48 other molecular targets screened. Ki determinations showed that Salvinorin A was a potent agonist of KOR and guinea pig (gp)KOR.
