Chemsex is a specific term which involves taking illegal drugs and engaging in hardcore sex, usually in groups.

It is a decades-old practice that has become increasingly more common.

People performing Chemsex are mostly gay, bisexual, trans or non-binary and ‘men who have sex with men’ (MSM) who, do not identify themselves as gay. Taking drugs like cigarettes and alcohol and then having sex is not classed as Chemsex.

Drug use is three times higher among gay and bisexual men, compared to those who are straight according to data from the Crime Survey for England and Wales 2013/2014.

The form of taking drugs explicitly for sexual purposes has existed for decades and traditionally called “slamming” however more recently the term Chemsex has become common.

Paramedics treat one person a day on Chemsex drugs

Between 2021 and 2023, the London Ambulance Service estimates it treated over 750 people in the capital who were engaged in the practice. At least 764 people were treated for intoxication from crystal meth or mephodrone.

The 3 main drugs, or chems, associated with Chemsex are nicknamed Crystal Meth, Meph and GHB/GHL. All of these are illegal under the Misuse of Drugs Act 1971, with Crystal Meth the most serious Class (A) and Meph and GHB in the same category as Cannabis (B). For all of these drugs, it is illegal to have, give away or sell and being caught could mean a lengthy prison sentence, fine or both. They are all highly addictive.

In 2015, a British documentary from Vice Media called “Chemsex” about the issue was released. Alongside, a powerful trailer was published:

The UK Health Security Agency, formerly Public Health England, and the NHS say that those who do Chemsex are at increased risk of blood-borne viruses and STIs due to lowering of inhibitions and practising unsafe sex.

London LGBT clinic 56 Dean St say that Chemsex happens is most common at parties, known as ‘chillouts’ which can be in private houses.

Although illegal, some who use chems to facilitate sex go to organised gay sex parties or gay saunas.
