What is Weed?
Marijuana (Weed) is a mixture of the dried and shredded leaves, stems, seeds, and flowers of Cannabis sativa—the hemp plant.
Of the more than 500 chemicals in marijuana, delta-9-tetrahydrocannabinol, known as THC, is responsible for many of the drug’s psychotropic (mind-altering) effects. It’s this chemical that changes brain activity, distorting how the mind perceives the world.
