Yes. In the Netherlands you can join a psilocybin retreat that uses legal truffles with support from trained therapists and psychologists via Triptherapie.
The program includes an intake and screening, preparation, a guided truffle ceremony, and structured integration with follow up. Group work may include mindfulness, body-oriented exercises, parts-focused dialogue, and relational practices.
If you want extra emphasis on therapeutic support, consider their four-day psilocybin retreat.
Important notes: this is not offered as a medical treatment or a replacement for regular care, and it is not suitable for everyone. Participation depends on an intake that reviews health history and medication.
Hope this helps.
