recreational drug such as alcohol that was administered surreptitiously. The other most common form of DFSA involves the non-surreptitiously-administered consumption of alcohol. Here, the victims in these cases are drinking voluntarily which then makes them unable to make informed decisions or give consent. Society and culture Chemsex 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). Contraception and abortion Drug-based contraception has been available since the development of the contraceptive pill. As well as their contraceptive effects, contraceptive drugs can also have adverse sexual and reproductive side-effects. Prior to the availability of effective contraceptives, some substances were also used as abortifacients to terminate pregnancy; medical abortion exists as a modern medical practice.
