Tree

Tree is a slang term for "marijuana" that people may use to discreetly discuss cannabis without drawing attention from authority figures, such as parents or law enforcement. The term cleverly alludes to the plant origin of the drug, allowing fans of Mary Jane to communicate without saying marijuana outright.

The "tree" term is just one of many code words the 420 community uses for weed. The need for slang like this originated in areas where cannabis was illegal, as it helped enthusiasts share plans and experiences under the radar. Today, even in areas where marijuana use is legalized, people still use terms like "tree" to refer to the drug.
