Joint is a slang term for a cigarette rolled using cannabis. Rolling papers are the most common rolling medium in industrialized countries; however, brown paper, cigarettes with the tobacco removed, beedis with the tobacco removed, tracing paper, ATM receipts, mango tree leaves and newspaper are commonly used in some developing countries. Modern papers are now made from a wide variety of materials including rice, hemp, and flax.
Joints consist of dried cannabis rolled inside a cylinder by hand or by a rolling machine. When smoked to the very bottom of the joint, it is often difficult to hold and is called a 'roach' or a 'crutch' in the United States. The roach will often have an appreciable amount of THC from the accumulated resin. The roach can be held with finger nails, roach clips, roach pins, tweezers, or can be smoked using a pipe.
Variations and terminology 
Though all joints customarily contain cannabis, regional differences have been noted. In Europe, certain Commonwealth nations, and more recently North America, joints, or spliffs, typically include a bit of rolled cigarette packet cardboard or business card in one end to serve as a mouthpiece. This is known as a filter or "roach." Other common terms used for the paper "filter" are "crutch", "tip" or "cut". (In North America, "roach" instead usually means the smoked-down butt of a joint, which can be finished off in a pipe, rolled into the lighting-end of a new joint, or saved for a cumulative all-roach joint.) In the past decade, filters have become more popular in North America as well.
The term spliff is sometimes used to distinguish a joint prepared with both cannabis and tobacco, as is commonly done in European countries, where joints containing only cannabis are rarely smoked. However, in the West Indies where this term originated (especially Jamaica), a spliff is simply a marijuana cigarette, normally containing no tobacco.
There are multiple methods of rolling a joint, sometimes known as classic, inside out, and tulip. Joint-rolling requires a certain level of skill, which can be honed with practice. There are various internet tutorials on joint rolling styles. Several aspects of joint-rolling can have an effect on the end product: the thickness of the rolling papers used, the mix of cannabis and tobacco, the use of a filter, and the quantity and quality of the cannabis.
The word joint ultimately originated from French, where it is an adjective meaning "joined" (past participle of the verb joindre), derived in turn from Latin iunctus, past participle of iugare ("join"/"bind"/"yoke").
By 1821, "joint" had become an Anglo-Irish term for an annexe, or a side-room "joined" to a main room. By 1877, this had developed into U.S. slang for a (usually unsavory) "place, building, establishment," especially referring to an opium den. By 1935, "joint" was being used to refer to the hypodermic needles used to inject heroin and other drugs at such establishments; this may have been influenced by the secondary meaning of "joint" in the sense of something done "in common" or shared. Its first usage in the sense of "marijuana cigarette" is dated to 1938.

The term spliff is a West Indian word of Jamaican English origin, but has spread to several western countries, particularly the UK, and many countries in Europe. Its precise etymology is unknown, but it is attested as early as 1936. While Jamaican spliffs are generally conical in shape, those elsewhere tend to be cylindrical and of varying lengths. A joint is also called a "doobie", mostly when rolled with king sized rolling papers.
