During this period, Henry (Harry) Anslinger, then-Commissioner of the Federal Bureau of Narcotics, alleged that the drug could provoke criminal behavior in previously solid citizens. Anslinger, originally against a federal law, switched his position in response to pressure from Southern and Western states seeking to outlaw the substance in connection with immigrant populations. With the aid of Hearst and other media, the Bureau of Narcotics demonized the herb in pop culture. Anslinger was a prohibitionist and believed anti-marijuana laws would help encourage a revival of alcohol's prohibition. Anslinger also popularized the word marihuana for the plant, using a Mexican derived word (believed to be derived from an archaic Brazilian Portuguese term for inebriation, "Maria Joana") in order to associate the plant with increasing numbers of Mexican immigrants, creating a negative stereotype which persists to this day.
