Fictional drugs are substances created for storytelling in books, movies, and video games. They often have unique effects, such as enhancing abilities, altering perceptions, or causing unusual transformations. These drugs can serve as plot devices, driving character development or conflict within the narrative. Examples of fictional drugs include Soma from Aldous Huxley's "Brave New World," which promotes happiness and conformity, and Spice from Frank Herbert's "Dune," which grants heightened awareness and extends life. Such drugs often reflect societal issues or moral dilemmas, making them significant elements in their respective stories.
