In the Netherlands, pure psilocybin and magic mushrooms are illegal. Psilocybin truffles, which contain the same active compound, can legally be sold and used. As a result, sessions marketed as psilocybin therapy typically use truffles. There is no approved medical psilocybin therapy in regular healthcare; clinical use happens only in research settings. For a practical overview of truffle-based sessions, see this page about psilocybin therapy.
Choosing a provider: this is an unregulated market, so do careful checks. Look for a proper intake and health screening that covers your medical history and medications. Some conditions and medicines can be reasons not to proceed. Skipping screening is a red flag.
Ask about preparation, continuous presence during the session, and structured integration afterward. Review the provider’s background, experience, and references. Relevant registrations such as BIG, NIP, or RBCZ add accountability, and a clear track record of supervised sessions helps.
If your themes are complex, consider someone with a psychotherapy or mental health background and agree on the approach in advance. Private sessions allow more tailoring, and some providers let your own therapist attend. I cannot verify individual providers, so compare carefully and ask detailed questions before you decide.
Hope this clarifies the basics and helps you choose safely.
