420chan is a long-standing imageboard founded in 2003 as a destination for cannabis enthusiasts and alternative subcultures. While it mimics the structure of 4chan, 420chan developed a unique identity through boards like /wooo/ for pro wrestling and /t/ for tobacco. The memes associated with 420chan often revolve around the site's distinct laid-back yet chaotic energy, its specific lingo, and its survival as one of the oldest niche communities on the web. Users frequently utilize the site's green-themed aesthetic or board-specific inside jokes to create memes that celebrate drug culture, internet history, and the specific brand of irony found within its threads.
