Our reading
This page reports only what providers publish about the price and terms of psilocybin-truffle programmes. It says nothing about whether they work for any purpose, and nothing here should be read that way.
In the Netherlands, the Minister of Health [answered parliamentary questions in 2011](https://zoek.officielebekendmakingen.nl/ah-tk-20112012-1032.html) that psychedelic truffles (sclerotia) do not fall under the Opium Act, and that this was known when 186 species of hallucinogenic mushrooms were placed on List II of the Opium Act from 1 December 2008.
Nine providers were checked on their own websites on 26 October 2026, and all nine publish a price. Prices are in euros, and the three formats below are separate comparisons.
For retreats of up to 3 days, Spinoza in Maarn publishes EUR 1,198 (≈ USD 1,341) with one night and VAT included, and Tangerine Retreat starts from EUR 1,990 (≈ USD 2,227) with two nights.
