Marijuana and stoner memes have been a cornerstone of internet culture since the early days of message boards and subreddits like r/trees. These memes typically revolve around 'high thoughts,' the physical effects of cannabis, or the stereotypical spaced-out behavior of smokers, most notably personified by the iconic 10 Guy template. They serve as a shared language for the 420 community, turning experiences like short-term memory loss, intense cravings, or sudden philosophical epiphanies into relatable humor. Over the years, the genre has evolved from simple image macros to complex visual gags, remaining a perennial favorite for their laid-back and often surreal nature.
