Chemsex is identified in the film as the habit of engaging in weekend-long parties fuelled by sexually disinhibiting drugs, such as crystal meth, GHB, GBL and mephedrone. These parties involve multiple people and are mostly facilitated online. The testimonies in the film from people involved in the subculture directly link chemsex to alarming rates of HIV infection. In London four new positive diagnoses are currently made daily. There is candid talk on film about “pozzing up”, the practise of knowingly becoming infected with the virus. Meth, meph and G create a potent cocktail enabling extremes of behaviour, which carries significant risks for the sexual and mental health of habitual users.
