About This Center

We are happy to announce the launch of a sitter service that we now offer as part of Psychedelic Society of the Netherlands activities. The sitter service is a one to one session with a carer with vast experience in psychedelic states and knowledge of human psychology and cognitive functions. The participant will be responsible for buying psilocybin truffles (legal in the Netherlands) and bringing them to the session. The sitter will only provide a safe set and setting for the psychedelic experience. As part of the service, we will inform you about the risks and make sure that there are no serious contraindications for you to take the truffles. Additionally, we will provide you with preparation and integration activities for the session. We use a scientific and therapeutic model of the psychedelic experience to enable you to have a memorable and long lasting positive effect.

There are two options available:

The sitter service provided by a cognitive scientist trained in psychedelic emergencies    

The cost of this service is 250 EUR for the whole day (including food but excluding truffles cost).

Included in the price is a short call to get to know each other and establish the dose of truffles for the client, intention preparation document, and around ten/eleven hours long sitter service session. The session consists of preparation conversation, psychedelic experience and integration discussion. During the integration part, the client will receive tips on how to integrate the experience into everyday life and recommendations for the next steps. 

The location is either a sitter’s house or a location chosen by the participant but in this case, the cost of the travel has to be added to the whole price.

The therapeutic sitter service provided by an accredited therapist

The costs of the therapeutic preparation and integrations sessions, before and after the psychedelic ceremony: 80 euros per hour (amount of the hours tailored to the needs of the participant).

 The cost of the ceremony day: 400 EUR. Included in this price is a session with truffles and a body-oriented preparation with holotropic breathwork assisted by two (male and female) sitters to maximize healing process (excluding the cost of truffles which need to be provided by the client).
 The location is the participant’s accommodation.

The program is carefully tailored between facilitators and client to meet financial resources and psychological needs.

 We have two standard frameworks which can be always adjusted to circumstances:

Program 1: 3 days ( Day 1: Preparation 2hrs, Day 2: Ceremony, Day 3: Integration 2hrs)

 Program 2 :  5 days (Day 1: Preparation session 2hrs, Day 2: Reflection from day before + breathwork + truffle ceremony ( 6-7 hrs),Day 3: 2 hours integration session ,Day 4: 2 hours integration session ,Day 5: Breathwork + truffle ceremony ( 5-6 hours)) + 1hr Integration next day or via Skype.

If you are interested in arranging a session please email us on (contact info blocked) and please indicate which option you prefer.

"Sitter Service has provided me with one of the most profound experiences of my life. Throughout the entire experience I felt incredibly safe and well looked after and would recommend it to anyone." "I can really recommend the retreats with PSN (especially Marta) who was a perfect host. She put me at ease with a new situation, she setup the perfect environment with blacked out windows, music of my choice, and a comfortable area with blankets for when I was getting cold. She brought me some fresh fruit when I was hungry and then cooked me a great vegetarian curry with rice. Can really recommend."


The preferred location is an Airbnb or participant's place. The space should have a bed or couch and conditions that allow for an uninterrupted ten/eleven hours long session. We can advise you on appropriate locations.

Menu Types

  • Vegan
  • Gluten Free


The sitter service with the cognitive scientist includes a post-session portion of fruit and vegan and gluten-free warm meal. Additionally, we accommodate each client's dietary needs.


The nearest airport is the main Dutch airport - Amsterdam Schiphol.
