Marijuana, also known by names like pot, weed, and grass, is a dry, shredded green/brown mix of flowers, stems, seeds, and leaves from the Cannabis sativa plant. It contains the psychoactive compound THC, which when smoked, eaten, or vaporized can cause effects like euphoria, relaxation, and altered perception but also carries health risks. While decriminalized for personal use of 10g or less in Belize, marijuana use can negatively impact teens' health and development, potentially leading to addiction or dependence over time. Both short and long term effects are described.
