The Medical History of Marijuana
The use of marijuana in medicine goes back to hundreds of years before the birth of Christ with numerous mentions of its healing power in the medical books of ancient China, India, Egypt and Greece. The early Chinese surgeon Hua Tuo (c. 140-208) is credited with being the first recorded person to use marijuana as an anesthetic. He reduced the plant to powder and mixed it with wine for administration prior to conducting surgery. The Chinese term for "anesthesia” literally means "marijuana intoxication"
In the medieval Islamic world, Arabic physicians made use of the diuretic, antiemetic, antiepileptic, anti-inflammatory, analgesic and antipyretic properties of marijuana, and used it extensively as medication from the 8th to 18th centuries. This carried forward into modern times with periods of interdiction and legalization. The watershed was the legalization of medical marijuana in 1996 in the State of California.
The Medical Benefits of Marijuana
In early 2017, the National Academies of Sciences, Engineering, and Medicine released a report based on the review of over 10,000 scientific abstracts from marijuana health research. They also made 100 conclusions related to health and suggested ways to improve marijuana research.
