Jasmine Virdi interviews Nidia Olvera Hernández, a Mexican ethnohistorian, specializing in the history of psychoactive substances and drug poilices. In this article, Nida shares about some of her earlier research into the history of marijuana in Mexico, detailing cannabis’ arrival with Span-ish colonizers who intended to use the plant for industrial purposes, and how the conception of the plant shifted over time, eventually coming to be referred to as “marijuana” as opposed to “hemp.”
