The common name for the plant known as cannabis is marijuana or hemp, depending on the intended use. Cannabis refers to a genus of flowering plants that produce compounds called cannabinoids, the most well-known being tetrahydrocannabinol (THC) and cannabidiol (CBD). Marijuana is typically associated with its psychoactive effects due to THC and is used recreationally and medicinally. In contrast, hemp is cultivated for industrial purposes, including fiber, seeds, and oil, and contains lower levels of THC. The legal status of cannabis varies by region and has been a subject of ongoing discussion regarding its medical and recreational use.
