Common Chemsex Substances and Their Health Risks

Substances in chemsex can strongly affect the body, emotions, and sexual behavior. In some highfun sessions, participants use alcohol, stimulants, or substances to enhance pleasure, prolong sexual activity, or reduce intimacy anxiety. However, using substances in chemsex can also reduce control, increase HIV and STI risks, and have long-term effects on mental health. Understanding the impact of each substance group is an important step to reduce harm and protect yourself.

What is chemsex?

Chemsex is the behavior of using substances before or during sexual activity to enhance excitement, prolong the experience, or create a stronger connection with a partner.

This activity often comes with many risks such as:

• Unprotected sex
• Long sexual activity causing mucosal damage
• Having multiple partners at the same time
• Reduced ability to make safe decisions
• Increased risk of substance dependence
• Increased risk of HIV and STIs

1. Alcohol in chemsex

Alcohol is one of the most commonly used substances in these sessions. When entering the body, alcohol affects the central nervous system, reducing inhibition and creating a relaxed feeling.

However, alcohol can also cause:

• Reduced judgment ability
• Slowed reaction
• Lack of body coordination
• Sleepiness or unconsciousness
• Increased risk of unsafe sex

When used with other substances, the risk of losing control and health complications can significantly increase.

2. MDMA or Ecstasy

MDMA is often used to create a feeling of euphoria, increase energy, and increase closeness with others.

Common effects include:

• Feeling happy
• Increased energy
• Increased emotional connection
• Temporary stress reduction

However, MDMA can cause dehydration, increased body temperature, anxiety, panic, disorientation, and mood drops after the effects end.

3. Poppers

Poppers are a group of substances inhaled to create a quick feeling of muscle relaxation and increased pleasure.

Some possible effects include:

• Quick euphoric feeling
• Temporary muscle relaxation
• Rapid heartbeat
• Dizziness
• Headache

Poppers should not be swallowed or ingested as it can be seriously dangerous. Overuse can cause difficulty breathing, fainting, or heart rhythm disturbances.

4. Ketamine

Ketamine can alter the perception of the body, space, and sound. In chemsex, some people use ketamine to create a relaxed feeling or a sense of detachment from reality.

Possible side effects include:

• Dizziness
• Nausea
• Rapid heartbeat
• Difficulty speaking
• Blurred vision
• Loss of behavioral control

When under the influence of ketamine, users may not recognize danger or make clear decisions about sexual consent.

5. Methamphetamine in chemsex

Methamphetamine, often called crystal meth, is a strong stimulant that can increase energy, reduce fatigue, and increase sexual desire.

However, this is one of the highest-risk substances in chemsex because it can cause:

• Prolonged insomnia
• Increased heart rate and blood pressure
• Delusions
• Psychosis
• Substance dependence
• Risk of heart attack, stroke, or coma

Methamphetamine also increases the risk of prolonged sexual activity, mucosal damage, and exposure to HIV or STIs.

Why do substances in chemsex increase HIV risk?

When using substances, the ability to make safe decisions can be affected. Participants may:

• Forget to use condoms
• Not use lubricants
• Have sex with multiple people
• Have sex longer than usual
• Not recognize injuries or bleeding
• Not remember clear risk behaviors that occurred

These factors increase the risk of HIV exposure and STIs such as syphilis, gonorrhea, chlamydia, HPV, herpes, and hepatitis B.

How to reduce harm when involved in chemsex

To reduce risks, prepare in advance:

• Condoms and lubricants
• Drinks and light snacks
• A plan to rest after the session
• A trusted person to support when needed
• Information about PEP if there is a risk of HIV exposure
• A regular HIV and STI testing schedule

Additionally, do not use multiple substances at once, do not drive after using substances, and do not continue sex if one person is not alert or cannot clearly consent.
