A lighter is a portable device which creates a controlled flame, and can be used to ignite a variety of flammable items, such as cigarettes, butane gas, fireworks, candles, or campfires. A lighter typically consists of a metal or plastic container filled with a flammable liquid, a compressed flammable gas and in rarer cases a flammable solid i.e. rope in a trench lighter, a means of ignition to produce the flame, and some provision for extinguishing the flame or merely controlling it to such a degree that the user may extinguish it with their breath. Alternatively, a lighter can be one which uses electricity to create an electric arc utilizing the created plasma as the source of ignition or a heating element can be used in a similar vein to heat the target to its ignition temperatures, as first formally utilized by Friedrich Wilhelm Schindler to light cigars and now more commonly seen incorporated into the automobile auxiliary power outlet to ignite the target material. Different lighter fuels have different characteristics which is the main influence behind the creation and purchasing of a variety of lighter types.

A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term cigarette, as commonly used, refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or a herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white.
