Cannabis is a plant grown and cultivated commercially across the globe. It is known by many names depending on its preparation and quality, including marijuana, trees, pot, dank, grass, green, kush, weed, hemp, hash, loud, and herb. These usually refer to the dried form or resin of the flowers or leaves of the plant. Scientists have identified multiple active compounds within cannabis (known as cannabinoids) that play a role in cannabis’ effects, including the psychoactive delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).
