"Reeferman" is a term that typically refers to a person involved in the illegal trade of marijuana, particularly in the context of the 20th-century jazz and blues scenes. The word "reefer" is slang for marijuana, and "man" denotes the individual engaged in its distribution or consumption. The term is also associated with a song by the legendary jazz musician Cab Calloway, which reflects the culture and lifestyle surrounding cannabis use during that era. In broader usage, it can symbolize the counterculture movements that embraced cannabis as part of their identity.
