Salvinorin A is the main active psychotropic molecule in Salvia divinorum. Salvinorin A is considered an atypical dissociative hallucinogen.
It is structurally distinct from other naturally occurring hallucinogens (such as DMT, psilocybin, and mescaline) because it contains no nitrogen atoms; hence, it is not an alkaloid (and cannot be rendered as a salt), but rather is a terpenoid. It also differs in subjective experience, compared to other hallucinogens, and has been described as having strong dissociative effects.
