Cannabis is a genus of plants in the Cannabaceae family. Both marijuana and hemp are varieties of the cannabis plant; however, they have extremely different practical uses. People have cultivated hemp for hundreds of years to utilize its fibrous stalks in the making of everything from textiles to sustainable building materials. Even founding father Thomas Jefferson grew hemp. Unlike marijuana, hemp contains minimal THC (tetrahydrocannabinol), the cannabinoid responsible for producing the “high” we associate with smoking marijuana. The variety of cannabis containing plenty of THC goes by many names: pot, weed, ganja, marijuana (though this term is falling out of favor due to its racist origin).
