How 'Marijuana' Became a Racialized Weapon in U.S. Cannabis Prohibition

The Linguistic Weapon of 1930s Prohibition

Federal prohibitionists deliberately adopted 'marijuana' in the 1930s to exploit anti-Mexican xenophobia and build public support for criminalization. Before that decade, U.S. pharmacopeias and medical texts used 'cannabis'—a Latin botanical term with no ethnic connotation. Harry Anslinger, the first commissioner of the Federal Bureau of Narcotics, seized on 'marijuana' (sometimes spelled 'marihuana') to frame cannabis use as a foreign threat tied to Mexican migration and Black jazz culture.

The 1937 Marihuana Tax Act codified this racialized framing into federal law. Congressional hearings featured testimony claiming the drug drove Mexican immigrants and Black Americans to violence and moral decay. The linguistic shift wasn't incidental. It was strategic, designed to distance the plant from its accepted medical uses and recast it as an alien danger.

The choice of 'marijuana' over 'cannabis' in federal statute wasn't neutral—it was a calculated move to make prohibition palatable by tying the plant to racial anxieties about immigration and integration.

Enforcement Patterns That Reflect the Language

Arrest data from the past century shows that racialized language translated directly into racialized enforcement. Despite roughly equal usage rates across racial groups, Black Americans have been arrested for cannabis possession at nearly four times the rate of white Americans, according to ACLU analysis spanning decades. Some states see that disparity exceed 9-to-1.

Sentencing disparities tell the same story. Mandatory minimums and three-strikes laws disproportionately incarcerated people of color for decades, even as white-owned businesses now capitalize on legalization in states like California, Illinois, and New York. Equity advocates argue the language itself—still embedded in state statutes and federal scheduling—carries forward the prejudice baked into prohibition's origins.

Reclaiming Language in the Legalization Era

Many equity-focused operators and advocates now insist on 'cannabis' to distance the legal industry from prohibition's racist roots. Social equity applicants in jurisdictions like Oakland, Los Angeles, and Chicago often describe the word choice as a deliberate reclamation, using clinical, botanical language to destigmatize the plant and honor communities harmed by the War on Drugs.

Some state agencies have followed suit. New York's Office of Cannabis Management and California's Department of Cannabis Control both use 'cannabis' exclusively in regulatory language. Yet federal law still refers to 'marihuana' in the Controlled Substances Act, a linguistic artifact that reform advocates say must be updated alongside any rescheduling or descheduling effort.

The debate over terminology isn't academic. It's operational. Licensing boards, banking compliance officers, and federal regulators still work through a patchwork of language that reflects an unresolved tension between prohibition's past and legalization's future. Until 'marihuana' disappears from the U.S. Code, the racialized history of American drug policy remains embedded in law.
