GSC (Girl Scout Cookies) is a popular, potent, indica-dominant hybrid known for euphoric, relaxing effects, strong dessert/mint/earthy flavors, and high THC (19-28%), with very low CBD, making it great for pain, appetite, and sleep, but start slow due to potency. Developed by Cookie Fam (Berner/Jigga) around 2009, it's a mix of OG Kush & Durban Poison, offering sweet, minty, and cookie-dough tastes with effects that can induce munchies and couch-lock, with common side effects like dry mouth and dizziness.
