Legal psilocybin therapy in the Netherlands: what is allowed and what is not?

The demand for psilocybin therapy is growing, including in the Netherlands. At the same time, there is much confusion regarding what is “legal,” what exactly is meant by psilocybin, and how therapy with psychedelics relates to scientific research, practical guidance, and safety. In this article, we clearly explain what is and is not permitted regarding psilocybin therapy in the Netherlands, with special attention to the difference between isolated psilocybin and magic truffles. We remain informative and nuanced throughout: there is research with promising signs, but there are also uncertainties, risks, and limits to what you can expect from a session.

What exactly is psilocybin?

Psilocybin is a substance that occurs naturally in certain mushrooms and truffles. In everyday language, “psilocybin” is often used as a collective term for “the active ingredient in magic mushrooms or truffles,” but chemically speaking, it is more specific. Psilocybin itself is actually a kind of “precursor.” In the body, it is converted into psilocin, and that substance is primarily responsible for the psychedelic effects.

In discussions about therapy, it is useful to be aware of this distinction, as it helps understand why some products or forms exist in research while others are used in practice. It does not automatically imply anything about quality, suitability, or safety. It primarily describes what happens in the body and how products fall within different legal and practical frameworks.

How does the conversion of psilocybin to psilocin work?

When someone ingests psilocybin, it is converted into psilocin in the body. This process is also known as metabolization. Psilocin can then bind to certain receptors in the brain, including serotonin receptors (often mentioned in scientific literature). This interaction is associated with changes in perception, emotional processing, meaning-making, and the experience of connection or, conversely, tension.

It is important to note that subjective experience can vary significantly. Set and setting play a major role in this: the mental state, expectations, intentions, the environment, and the quality of guidance or support. This is also a reason why “therapy” or guided sessions emphasize preparation, context, and post-session integration, rather than focusing solely on the subject matter.

What does science say about psilocybin and therapy?

International scientific research has been conducted into psilocybin in therapeutic contexts, for example for specific psychological complaints. Many studies are small-scale or conducted under strict research conditions. The results are viewed by some as promising, but it is important to emphasize that research is no guarantee of individual outcomes. Additionally, studies differ in design, dosage, supervision, selection criteria, and measurement methods. This makes it difficult to draw general conclusions that apply to everyone.

There is also a difference between the research context and what people look for in practice. Research works with protocols, medical screening, ethical review, and rigorous monitoring. Practical settings may partially resemble these, but are not automatically the same. It is therefore wise to continue to critically examine claims and grand promises, especially online.

What is allowed in the Netherlands: truffles as a legal alternative

In the Netherlands, isolated psilocybin is not freely available. In practice, this means that its use is generally only permitted within scientific research with the appropriate authorization and guidelines. At the same time, legal alternatives exist that also contain psilocybin, such as magic truffles. Truffles naturally contain psilocybin and psilocin and, unlike many other forms of psilocybin, are permitted to possess in the Netherlands.

As a result, you regularly hear that “psilocybin therapy in the Netherlands is possible via truffles”. That is essentially what is meant: not that isolated psilocybin is freely used as a substance, but that within the legal range of truffles, there is a route to work with comparable active substances.

When is something 'therapy' and when is it a guided session?

The word “therapy” is used broadly. Sometimes it refers to a process involving intake, preparation, a guided experience, and integration. At other times, the word is used as a label for a single session or retreat. This distinction is relevant because expectations can change. Ideally, information about psychedelic therapy covers not only the experience itself but also preparation (such as discussing intentions, contraindications, and agreements regarding support) and integration (such as meaning-making, behavioral change, and aftercare).

In addition, it remains important to distinguish between three types of information: scientific research (with protocols and data), anecdotal evidence (personal and not generalizable), and practical information (such as risks, setting, and guidance). If one of these three is missing, the picture can quickly become skewed.

Safety and harm reduction: what you definitely need to know

Even if something is legal, it is not automatically risk-free. Harm reduction is about limiting risks and increasing safety, without pretending that guarantees exist. With psychedelics, this involves, among other things: screening for vulnerabilities, proper preparation, a safe setting, clear agreements regarding guidance, and attention to integration. It is also wise to take into account possible difficult experiences, such as anxiety, confusion, or reliving intense emotions.

We do not provide individual medical advice here, but in general, people with certain mental or medical vulnerabilities should exercise extra caution and may require professional assessment. Combination use with other substances or certain medications can also increase risks. If in doubt, it is advisable to discuss this with a qualified healthcare professional and not to draw conclusions independently based on online information.

How does this relate to MDMA sessions?

Much information on mdmatherapie.nl concerns MDMA, trauma, and therapy. It is important to remain clear regarding this: MDMA sessions can currently only be discussed within scientific research or in clinical practice via harm reduction. This means that the context, goals, and preconditions may differ from, for example, truffle programs that fall within the permitted range of services. In both cases, it is important to avoid claims and prioritize safety, precisely because personal reactions can vary widely.

Conclusion

“In practice, ”legal psilocybin therapy” in the Netherlands is often facilitated through magic truffles, as these contain psilocybin and psilocin and are legally permitted to possess. Isolated psilocybin generally falls under stricter regulations and is primarily linked to scientific research. Anyone delving into therapy with psychedelics would do well to distinguish between research, anecdotal evidence, and practical information, and to take safety and harm reduction seriously. If you wish to explore guided sessions and discuss the possibilities within a careful, harm-reduction-oriented approach, you can find more information via sign up for a session.
