A habit-forming substance derived from the Indian hemp plant, Cannabis sativa, typically consumed by smoking in cigarettes. Studies on its intoxicating effects have noted temporary outcomes including redness of the eyes, a mild increase in heart rate, memory lapses, irritation of lung tissue, and a slight decline in performance on psychomotor tests. Users of marijuana often report experiencing euphoria, altered perceptions of beauty, distortions in vision and spatial awareness, and more. To fully understand its long-term effects, additional scientific research is required. This substance is also known by various names, including cannabis, hashish, marijuana, grass, weed, pot, and Indian hemp.
