See also, quotes like 'Nicole Scherzinger ‘sniffed poppers’ at a gay bar'. Such a phrase wouldn't make sense if we gloss 'poppers' as the plural of the sense 'a capsule of amyl nitrite'. For starters, 'bottle of poppers' has a huge number of hits on google and google books.SemperBlotto ( talk) 07:31, 6 February 2021 (UTC)

Rfv-sense: '(informal, plural only) Drugs of the alkyl nitrate class used recreationally as a sexual stimulant, especially among gay men.'
