Weed
The word weed appeared in 1929, at a time when Americans were beginning to smoke cannabis, between the Roaring Twenties and the Great Depression.
According to the Oxford English Dictionary, The term first appeared in print in 1932. The Chicago Defender, a weekly newspaper dubbed «the most dangerous of the Negro papers», commented on the migration of cannabis in New York City from the slums to high society.
«The vile joint, weed, marijuana, or whatever you call this doctored cigarette, has moved from Harlem to Park Avenue.».
The term weed spread to the UK through the magazine Melody Maker. In 1932, this renowned magazine advised its readers to listen to «Song of the Weed» and «Reefer Man».
Unfortunately, there is no recording of «Song of the Weed», but Cab Calloway's rendition of «Reefer Man» still exists.
For years, the word weed has remained fairly confidential. If you look at the Ngram from Google (a tool that shows how often a word is used, only for US sources), weed became popular in France in the 1990s. Today, the word lives on in the USA as well as in Europe, and must be one of cannabis synonyms with weed.
