The book Cannabis: Global Histories, edited by Lucas Richert and James H. Mills contains at least two chapters that are relevant for those interested in the history of psychiatry: “Taming the Orient: France and the First Global Movement to Medicalize Cannabis, ca. 1800-1850”, by David A. Guba Jr. and “Ganja Madness: Cannabis, Insanity and Indentured Labor in British Guiana and Trinidad, 1881-1912”, by Jamie Banks.
