Explainer: The science of alkyl nitrites aka poppers
From their origins as 19th century angina treatment to becoming an important part of gay subculture, these recreational drugs exist in a legal limbo
Inhaling alkyl nitrites feels like becoming instantly drunk according to some users, although the effect lasts for only a few minutes. Also known as poppers, these chemicals have been taken recreationally since the 1960s. Although they are sold openly, usually in small brown bottles with enticing brand names such as ‘liquid gold’, their consumption remains a legal grey area. While they have gone in and out of fashion over the years, they continue to be an important part of gay subculture.
