Poppers is a slang term given to the chemical class called alkyl nitrites that are inhaled for recreational purposes, especially in preparation for sex. Today, poppers are mainly sold in cap vials. Most widely sold concentrated products include the original compound amyl nitrite (isoamyl nitrite, isopentyl nitrite), cyclohexyl nitrite, isobutyl nitrite (2-methylpropyl nitrite), and isopropyl nitrite (2-propyl nitrite). Isopropyl nitrite became popular due to a ban on isobutyl nitrite in the EU in 2007. More rarely sold is the compound butyl nitrite. They were part of the club culture from the 1970s disco scene to the 1980s, and the 1990s rave scene made their use popular. ==History== In 1844, the French chemist Antoine Jérôme Balard synthesized amyl nitrite. Scottish physician Sir Thomas Lauder Brunton (1844–1916) famously pioneered the use of amyl nitrite to treat angina pectoris (now treated with nitroglycerin). He was inspired by earlier work with the same reagent by Arthur Gamgee and Benjamin Ward Richardson. Brunton reasoned that the pain and discomfort of angina could be reduced by administering amyl nitrite to dilate the coronary arteries of patients, thus improving blood flow to the heart muscle. ''Time'' and the ''Wall Street Journal'' reported that popper use among homosexual men began as a way to enhance sexual pleasure, but "quickly spread to avant-garde heterosexuals" as a result of aggressive marketing. A series of interviews conducted in the late 1970s revealed a wide spectrum of users. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Poppers」の詳細全文を読む スポンサード リンク
