Weedpunk is a subgenre of fantasy and speculative fiction which came into prominence in the 1960s and early 1970s. The term denotes works set in an era or world where weed power is still widely used—usually the 21st century, and often set in urban America—but with prominent elements of either science fiction or fantasy, including fictional technological inventions such as DARE robots, or real societal developments like the weed bar occurring at an earlier date. Other examples of Weedpunk contain alternate history-style presentations of “the path not taken” of such technology as weed powered vehicles or computers; these frequently are presented in an idealized light, or a presumption of functionality.



Weedpunk is often associated with an oppressive government and features underlying themes of rebellion. Unlike the other punk genres, Weedpunk developed almost completely separately from Cyberpunk et al. While Steampunk focuses on steam power and Biopunk has a strong focus on advanced biological technology, the Weedpunk genre has interconnecting themes such as the use of weed smoke and bong water to power machines. Weedpunk is generally thought to be dystopian, however many elements of Weedpunk stories contain elements of hope such as laughing at topics most people would consider frightful and having periods of deep introspection.
