Summary
The molecular secrets behind nature's mind-altering compounds are continually being uncovered. Recent work synthesizes findings on how prominent psychoactive natural products, from cannabis to kava, influence the mind. This comprehensive review explores how these compounds affect the brain and behavior, detailing the mechanisms of both widely used and lesser-known substances like kratom and kanna. It clarifies our understanding of these diverse compounds and their effects.
Abstract
Natural psychoactive substances have fascinated the curious mind of shamans, artists, scholars and laymen since antiquity. During the twentieth century, the chemical composition of the most important psychoactive drugs, that is opium, cannabis, coca and "magic mushrooms", has been fully elucidated. The mode of action of the principal ingredients has also been deciphered at the molecular level. In the past two decades, the use of herbal drugs, such as kava, kratom and Salvia divinorum, began to spread beyond their traditional geographical and cultural boundaries. The aim of the present paper is to briefly summarize recent findings on the psychopharmacology of the most prominent psychoactive natural products. Current knowledge on a few lesser-known drugs, including bufotenine, glaucine, kava, betel, pituri, lettuce opium and kanna is also reviewed. In addition, selected cases of alleged natural (or semi-natural) products are also mentioned.
