Joint is slang for a cigarette rolle using cannabis. Usually, rolling papers are used in industrialised countries, while in the developing world, brown paper, cigarettes with the tobacco removed, or newspaper are often used. Blunt cigar paper is also used to roll marijuana, after the tobacco is discarded. Some papers used for rolling are made of rice paper. Some manufacturers use hemp as an alternative. One of the newest innovation in joint-rolling technology has been the introduction of transparent cellulose-based rolling papers. For more details see clear rolling papers.
