Fresh magic truffles, Hollandia included, are legal to buy and possess in the Netherlands. Dried truffles are not. Outside the Netherlands, psilocybin truffles are illegal in almost every country, and taking them across a border can lead to prosecution for drug import.
This page describes the law as we found it on 10 October 2026, with sources. It is general information, not legal advice. Laws change; check the current rules where you are.
The Netherlands
Since December 2008, mushrooms that contain psilocybin or psilocin are banned in the Netherlands. The ban covers the mushrooms, not the sclerotia. Truffles therefore fall outside the Opium Act, and the Supreme Court confirmed in April 2026 that they can be grown and sold freely (Hoge Raad, ECLI:NL:HR:2026:450).
Three limits apply:
- Do not dry them. No court has ruled on dried truffles, and the Jellinek classes them as a List I drug under the Opium Act, the same category as cocaine (Jellinek). Do not dry Hollandia to make it last longer.
- No driving. Taking part in traffic under the influence of truffles is prohibited (Jellinek). Leave the bicycle too: your reactions are impaired for hours.
- Adults only. Avalon Magic Plants sells truffles only to people aged 18 or over, and this site is written for adults.
If you are visiting the Netherlands, buy and use truffles during your stay, and do not take what is left home.
Germany
Psilocybin and psilocin are listed in Annex I of the Narcotics Act (BtMG) as substances that may not be traded or prescribed (BtMG Anlage I). The Act defines substances to include fungi and their parts (§ 2 BtMG), so fresh and dried truffles count as narcotics. Possession, purchase, import and trade can be punished with up to five years in prison or a fine (§ 29 BtMG).
United Kingdom
Since 18 July 2005, any fungus that contains psilocin or an ester of psilocin is a Class A drug under the Misuse of Drugs Act 1971, whether fresh or prepared (Drugs Act 2005, section 21). Class A is the most serious category in British drug law.
United States
Psilocybin and psilocin are Schedule I controlled substances under federal law (21 CFR 1308.11). Possessing or importing truffles that contain them is a federal offence.
Other countries
Psilocybin and psilocin are listed in Schedule I of the 1971 UN Convention on Psychotropic Substances (INCB Green List), and almost all countries control them under national law. Countries differ in how their laws cover the fungi and truffles that contain them, and in how strictly they enforce.
Travelling with truffles
Open borders within the Schengen area mean there are usually no checks. They do not make it legal to bring truffles into a country where psilocybin is controlled. Ordering truffles by post to such a country counts as import as well, and the risk lies with the person who orders.
The safe rule is simple: use them where you bought them, in the Netherlands, and leave none in your luggage.
