Understanding chemsex

When Chemsex Becomes Difficult

Chemsex usually refers to the use of drugs such as crystal methamphetamine, GHB/GBL and mephedrone to enhance, prolong or disinhibit sex. It is most often discussed in relation to gay and bisexual men, though the experience is not limited to them.

Not everyone who engages in chemsex develops an addiction. It helps to distinguish between three different situations, which can shift over time:

01

Recreational use

Occasional use that feels chosen and contained, with little impact on the rest of life.

02

Problematic or harmful use

Use that is causing harm — to health, relationships, work or self-respect — even if it isn't constant.

03

Dependence or addiction

Use that has become hard to control, with cravings, escalation and repeated unsuccessful attempts to stop.

Common concerns people bring

  • Losing control over how often or how long you use
  • Finding it difficult to enjoy sex without drugs
  • Anxiety, shame or isolation after sessions
  • Conflict or secrecy in a relationship
  • Difficulties with sexual functioning
  • Repeated attempts to reduce or stop
  • Effects on work, sleep, health and wellbeing

The approach

Therapy That Starts With Understanding, Not Judgement

The work is tailored to you. It does not assume that everyone must commit to lifelong abstinence from the first session. Depending on your circumstances and goals, therapy may involve understanding harmful patterns, reducing risk, changing behaviour, or working toward abstinence.

That is not the same as treating continued use as safe. Where use is causing serious harm, that will be named clearly and taken seriously.

The approach is integrative, drawing on CBT, psychodynamic, existential and humanistic perspectives.

Couples

When Chemsex Affects Your Relationship

Chemsex can reshape trust, intimacy, boundaries, sexual expectations and emotional security within a relationship — sometimes gradually, sometimes all at once.

Partners may disagree about drug use. One may feel responsible for monitoring the other. Cycles of permission, conflict and blame can develop that neither person wants but both feel caught in.

Couples therapy aims to understand the relationship dynamic as a whole, rather than automatically identifying one partner as the sole problem.

Published work

The Author of The Truth About Chemsex

Justin Duwe is the author of The Truth About Chemsex, a book exploring the complex relationship between drugs, sex, identity, intimacy and addiction.

His clinical work recognises that chemsex is not a single experience. Some men engage recreationally, others develop problematic patterns, and some experience dependence or addiction.

Drawing on more than two decades of therapeutic experience, Justin works with individuals and couples to understand the psychological, sexual and relational factors underlying their experiences.

Chemsex Freedom

Prefer to Work Independently?

Not everyone who wants to change their relationship with chemsex is looking for therapy.

The programme is separate from psychotherapy and does not provide individual clinical treatment.

Questions

Frequently Asked Questions

What is chemsex therapy?

Chemsex therapy is psychotherapy focused on the use of drugs such as crystal methamphetamine, GHB/GBL and mephedrone in sexual contexts. It looks at what the drugs and the sex are providing, what they have begun to cost, and what you want to change — alongside the emotional, sexual and relational questions that usually sit underneath.

Do I have to stop using drugs to start therapy?

No. You do not need to have stopped, or to have decided to stop, before you begin. Some people work toward abstinence; others first need to understand their use, reduce harm or regain control. Goals are agreed together and revisited honestly. Where use is creating serious risk, that will be discussed openly rather than ignored.

Can chemsex become addictive?

It can. Not everyone who engages in chemsex develops a problem, but the drugs involved can lead to dependence, and the pairing of drugs with sex can become a powerful, hard-to-break pattern. Signs include using more or for longer than intended, repeated failed attempts to cut down, and finding sex difficult or unappealing without drugs.

Can therapy help me enjoy sex without drugs?

Many people come to therapy with exactly this concern. Therapy can explore anxiety, shame, confidence, desire and intimacy, and the ways drugs have come to stand in for them. Change is individual and cannot be guaranteed, but this is a central and realistic focus of the work.

Can couples attend chemsex therapy together?

Yes. Couples therapy is available where chemsex is affecting a relationship — whether one or both partners use. The work focuses on the relationship dynamic, trust, boundaries and communication, rather than identifying one partner as the problem.

Is online chemsex therapy confidential?

Yes. Sessions are private and held online by secure video, from a space of your choosing. Confidentiality operates within the usual professional limits — for example, where there is a serious risk of harm — and these limits are explained at the outset.

How long does chemsex therapy take?

It varies. Some people find a focused period of work enough; others benefit from longer-term therapy. No fixed number of sessions is promised. Progress and direction are reviewed together as the work develops.

What happens if I relapse?

Relapse is common and is not a reason to end therapy or to feel ashamed. It is treated as information — about triggers, needs and circumstances — that can make the next stage of the work more effective.

Can I attend therapy if I'm not sure I have an addiction?

Yes. You don't need a label or a diagnosis. Many people begin simply because they are questioning the role chemsex plays in their life, and want a confidential space to think it through.
