Green Crack is a popular sativa-dominant cannabis strain known for its sharp, fruity aroma (mango, citrus) and energizing, focus-enhancing effects, making it a favorite for daytime use to combat fatigue, stress, and depression, with effects often described as a "jolt" of energy and mental clarity, similar to a coffee boost, though its exact genetics trace back to Skunk #1 and Afghani landraces.
