ChemSex is the use of recreational drugs during sex. The 3 specific drugs used are Crystal Meth, GHB and Methedrone.

Crystal Meth (aka Methamphetamine / Tina / Ice): Crystal meth is a very powerful stimulant that can be smoked, snorted or injected.

GHB (aka GBL / GHB / G / Gina / Geebs / Liquid Ecstasy): GHB is a depressant drug which can come as a clear liquid with a salty taste or as a white powder.

Methedrone (Meow / M-Cat / Drone): Mephedrone is a stimulant drug in the form of a white powder that can be snorted, swallowed or injected.

They can give feelings of heightened pleasure, increase stamina (often meaning you stay awake for days at a time) and sexual disinhibition.

Using drugs during sex can increase risky behaviour, including decreasing condom use, increasing number of partners and sharing injecting equipment which increases you risk of Hepatitis and HIV.

The drugs involved are also addictive and have risks including overdose, mental health problems including psychosis and even death. They are particularly dangerous when mixed with alcohol.

If you are on other medications, for example drugs to treat HIV, there can be interactions between these and the chemsex drugs. This can make them even more dangerous.
