Party and play, or chemsex, is the consumption of drugs to facilitate sexual activity. Sociologically, both terms refer to a subculture of recreational drug users who engage in high-risk sexual activities under the influence of drugs within groups. The term PnP is commonly used by gay men and other men who have sex with men (MSM) in North America, while chemsex is more associated with the gay scene in Europe. The drug of choice is typically methamphetamine, known as tina or T, but other drugs are also used, such as mephedrone, GHB, GBL and alkyl nitrites (known as poppers).
