A Five-Minute History: Cannabis Research

Cannabis has long been used as medicine—going back at least 6,000 years around the world.

Researchers report that records of cannabis use date to 2,700 years ago in Ancient China, where it is believed to have been used as an anesthetic. It played a role in Ayurvedic medicine in India, and its use was also documented in Egyptian papyri.
