Cannabis smoking

Cannabis smoking is the inhalation of smoke or vapors released by heating the flowers, leaves, or extracts of cannabis. Smoking releases the main psychoactive chemical in cannabis, Δ⁹-tetrahydrocannabinol (THC), which is absorbed into the bloodstream via the lungs.

Apart from being smoked and vaporized, cannabis may be consumed orally or applied to the skin; the bioavailability characteristics and effects of smoking and vaporizing cannabis differ from other consumption methods in having a more rapid and predictable onset of effect.

Smoking methods

Cannabis can be smoked in a variety of pipe-like implements made in different shapes and of different materials ("bowls"), water pipes ("bongs"), cigarettes ("joints"), or blunts.

Joint

Joint is a slang term for a cigarette rolled using cannabis. Cannabis joints are made with pure herbal cannabis, or a common variation is the imbiber's choice of cannabis mixed with tobacco (commonly dubbed "a spliff" in Jamaica) or various non-addictive herbs; a filler is often used to help hashish burn in a joint. Specially manufactured rolling papers are most often used in industrialized countries; however, recycled brown paper and newspaper are commonly used in the developing world. Modern papers are now made from a wide variety of materials including rice, hemp, and flax. A joint typically contains 250–750 mg net weight of cannabis and/or fillers.
