(NEWSER) – The Washington Post wades through the weeds to get the linguistic scoop on weed—specifically, why an "archaic" spelling of marijuana is still in use. A Federal Register post last week announcing that CBD hemp oil is now considered a Schedule 1 drug offered a new code for "marihuana extract" and spelled it thusly in the dedicated section. But while some pot advocates have mused the alternate spelling may have been employed as a way to dodge web searches on marijuana policy changes, the Post takes a closer look at a spelling "freighted with historical significance." To wit: In the late 19th century, the pot plant was usually just called "cannabis," but things changed after 1898's Spanish-American War, when "American resentment toward Mexicans and Mexican immigrants exploded," per Brookings Institution expert John Hudak.
