# "Headies" is a slang underground term for extremely high-grade, expensive marijuana. It refers to types of cannabis that are very distinct in appearance, smell, taste, and euphoric properties. The term ''headies'' is used to differentiate the best, highest quality varieties of marijuana from the slightly less potent type of cannabis which is widely distributed throughout the United States from British Columbia, Canada known as ''B.C. bud'' or ''beasters.'' Both headies and B.C. bud are extremely potent, boasting very high levels of THC; however, headies are strains of marijuana that are distinguishable by color, bud formation, classification as indica or sativa, and by the name of the strain. These typically have the highest THC levels of all cannabis. A few examples of heady strains of marijuana are ''"Northern Lights," "Jack Herer," "Kush," "Purp"'' (named so because the bud is literally purple), and ''"Blueberry"'' (again, named so for it's similarity to the taste and smell of blueberries). The catalog of high-grade marijuana grows each year as seed companies and industrious individual growers experiment, creating new types, or hybrids, by cross-breeding strains.
