A joint (pronunciation: /dʒɔɪnt/) is a rolled marijuana cigarette. Unlike commercial tobacco cigarettes, joints are ordinarily hand-rolled by the user with rolling papers, though in some cases they are machine-rolled. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes with the tobacco removed, beedis with the tobacco removed, receipts, and newspaper can also be used, particularly in developing countries. Modern papers are manufactured in a range of sizes from a wide variety of materials including rice, hemp, and flax, and are also available in liquorice and other flavoured varieties.
