kratomThe leaves of kratom, a native of Southeast Asia in the coffee family, are used to relieve pain and improve mood as an opiate substitute and stimulant. The herb is also combined with cough syrup to make a popular beverage in Thailand called "4x100." Because of its psychoactive properties, kratom is illegal in Thailand, Australia, Myanmar (Burma) and Malaysia. Thailand is considering legalizing kratom as a safer alternative for meth addicts, and U.S. researchers are studying its potential to help opiate abusers kick the habit without withdrawal side effects.
