Poppers

Popper is a slang term given broadly to recreational drug of the chemical class called alkyl nitrites that are inhaled. They act on the body as vasodilators. Most widely sold products include the original isoamyl nitrite, isopentyl nitrite, and isopropyl nitrite. Isobutyl nitrite is also widely used but is banned in the European Union. In some countries, poppers are labeled or packaged as room deodorizers, leather polish, nail polish remover, or videotape head cleaner to evade anti-drug laws.

Popper use has a relaxation effect on involuntary smooth muscles, such as those in the throat and anus. It is used for practical purposes to facilitate anal sex by increasing blood flow and relaxing sphincter muscles. The drug is also used for recreational purposes, typically for the "high" or "rush" that the drug can create, and to enhance sexual pleasure in general.

In popular culture, poppers have been part of club culture from the mid-1970s disco scene and surged in popularity in the 1980s and 1990s rave scene.
