Documents espousing marijuana’s medical benefits first appeared in 2900 B.C. in China, but medicinal cannabis in Europe is indebted to one over-achieving Irishman. Born in 1809, Dr. William Brooke O’Shaughnessy invented the modern treatment for cholera, laid the first telegraph system in Asia, contributed inventions in underwater engineering, and effectively pioneered the use of medical cannabis in Europe. Inspired by the use of cannabis in Ayurvedic and Persian medicine, O’Shaughnessy conducted the first clinical trials of marijuana, treating rheumatism, hydrophobia, cholera, tetanus, and convulsions.
