Kratom (Mitragyna speciose) is a tropical tree from Southeast Asia whose leaves are traditionally chewed or prepared as a powder. Native populations chew the leaves to reduce fatigue when doing manual labor, such as working on rubber plantations. It is also used in cultural performances and consumed as a drink prepared from kratom powder. When the Second World War caused an increase in the price of opium, Thai addicts forced to cut back on opium consumption used kratom to ease their withdrawal symptoms. Thailand and other Southeast Asian countries have passed laws controlling its use and other countries have followed suit, including Australia and New Zealand where it is banned.
In the past several years, kratom consumption has spread beyond traditional uses and the confines of Southeast Asia. In the U.S., it is widely available in head shops, kava bars, and on the internet. It is touted as a legal, psychoactive alternative to other sedative and stimulant-type drugs, both legally and illegally obtained. It is marketed for opioid and alcohol withdrawal symptoms, chronic pain and appetite reduction, among other things. There is also anecdotal evidence of naturopaths prescribing it for opioid withdrawal and depression. (more…)
