Chemsex
Chemsex is the intentional use of certain recreational drugs before or during sex to enhance, prolong, or intensify sexual experiences. It is most commonly associated with gay, bisexual, and other men who have sex with men (MSM), though people of any orientation may participate in it. Chemsex is often connected to group sex, hookup apps, private parties, and extended sexual sessions.
Because the substances involved carry physical risks and can also impair judgment, chemsex comes with significant health and safety concerns. Depictions of illegal drug use are against FetLife's Rules and Policies.
The drugs most commonly linked to chemsex include:
- Methamphetamine: A powerful stimulant that can increase energy, confidence, libido, focus, and sexual endurance. It is associated with very long sexual sessions and a reduced need for sleep.
- GHB/GBL: Depressant drugs that can create feelings of euphoria, relaxation, emotional openness, and increased physical sensation. They may also lower inhibitions and anxiety.
- Mephedrone: A synthetic stimulant that may increase arousal, sociability, emotional intensity, physical sensitivity, and physical energy.
- Alkyl Nitrites (“poppers”): Inhalants that create a short-lived rush and muscle relaxation. They are sometimes used during sex because they can relax smooth muscles, including during anal sex, and may intensify physical sensation.
Origins of the Term
The term “chemsex” is believed to have emerged in the U.K. gay community during the late 2000s and early 2010s. While people have long combined drugs and sex in many cultures and subcultures, chemsex became associated with substances like methamphetamine, GHB/GBL, and mephedrone among gay, bisexual, and other men who have sex with men. The rise of hookup apps, private group sessions, and changing queer nightlife culture all contributed to the growth and visibility of chemsex culture.
Chemsex Statistics
- A 2025 global meta-analysis of studies of men who have sex with men estimated that 22% had had chemsex.
- A 2025 study found that about 12.7% of the general population had engaged in chemsex.
- The most commonly used substances were GHB/GBL (13%), methamphetamine (8%), and mephedrone (7%).
- Chemsex is associated with a higher number of sexual partners, condomless sex, and increased STI risk.
Why People Are Into It
People engage in chemsex for many different reasons. Here are a few:
Intense Sensation and Immersion
One of the main appeals of chemsex is the way certain drugs can intensify physical sensation, arousal, and emotional intensity. People often describe feeling more sexually open, more physically sensitive, and more willing to explore fantasies or kinks. Extended sessions, marathon edging, and group sex are common in chemsex.
Escape from Shame, Anxiety, Self-Consciousness
Many people describe chemsex as temporary relief from loneliness, rejection, insecurity, or social anxiety. This can feel especially powerful in queer communities where body image pressures, stigma, trauma, or experiences of exclusion are more common.
Intimacy and Emotional Openness
People involved in chemsex sometimes describe unusually intense feelings of closeness, vulnerability, and connection. Long nights of sex, conversation, touch, and shared intoxication can create an atmosphere of intense intimacy. Some participants describe it as cathartic or emotionally freeing.
Excess and Altered Time
Chemsex is often associated with experiences that feel outside normal time and routine. This can include things like staying awake for long periods, extended sexual encounters, losing track of time, and temporarily escaping "real life." For some people, this creates a feeling of total freedom or release.
Safety and Consent
The drugs most commonly associated with it can carry serious physical, emotional, and sexual health risks. Depending on the substances involved, risks may include:
- Overdose
- Blackouts
- Psychosis
- Dehydration
- Sleep deprivation
- Dangerous drug interactions
- Impaired judgment
- Addiction
- Long-term mental health effects
Extended sessions can also increase the risk of physical injury and exhaustion. Because chemsex impairs judgment and tends to be associated with multiple partners and lower condom use, it may also increase the risk of sexually transmitted infections (STIs).
Here are some recommendations commonly given for reducing risk during chemsex. Note that none of these measures make the activity safe. Suggestions may include:
- Staying hydrated and cool as stimulants can raise body temperature.
- Avoiding mixing substances.
- Using sterile equipment to reduce the risk of infection.
- Limiting frequency and dosages.
- Using safer sex practices such as condoms and PrEP for HIV prevention.
- Obtaining consent and negotiating limits while sober.
