Mexican immigrants referred to this plant as “marihuana”. While Americans were very familiar with “cannabis” because it was present in almost all tinctures and medicines available at the time, the word “marihuana” was a foreign term. So, when the media began to play on the fears that the public had about these new citizens by falsely spreading claims about the “disruptive Mexicans” with their dangerous native behaviors including marihuana use, the rest of the nation did not know that this “marihuana” was a plant they already had in their medicine cabinets.

The demonization of the cannabis plant was an extension of the demonization of the Mexican immigrants. In an effort to control and keep tabs on these new citizens, El Paso, TX borrowed a play from San Francisco’s playbook, which had outlawed opium decades earlier in an effort to control Chinese immigrants. The idea was to have an excuse to search, detain and deport Mexican immigrants.

That excuse became marijuana.

This method of controlling people by controlling their customs was quite successful, so much so that it became a national strategy for keeping certain populations under the watch and control of the government.

During hearings on marijuana law in the 1930’s, claims were made about marijuana’s ability to cause men of color to become violent and solicit sex from white women. This imagery became the backdrop for the Marijuana Tax Act of 1937 which effectively banned its use and sales.

While the Act was ruled unconstitutional years later, it was replaced with the Controlled Substances Act in the 1970’s which established Schedules for ranking substances according to their dangerousness and potential for addiction. Cannabis was placed in the most restrictive category, Schedule I, supposedly as a place holder while then President Nixon commissioned a report to give a final recommendation.“
