Psychedelic Research in

Belgium

Belgium remains a tightly controlled, research-led environment for psychedelic medicine. The national framework is administered by the Federal Agency for Medicines and Health Products (FAMHP), which points to the 24 February 1921 drug law and the Royal Decree of 6 September 2017 as the legal basis for narcotics and psychotropics.

Key Insights

A concise read of the policy, research, and stakeholder signals shaping psychedelic medicine in Belgium.

  • 1

    Belgium is not a legal-access jurisdiction for classical psychedelics; it is a conventional medicines-and-trials jurisdiction.

  • 2

    FAMHP Annex IIA valid from 29 March 2026 expressly lists DMT, LSD, MDMA, mescaline, psilocin and psilocybin.

  • 3

    Spravato is the clearest authorised and reimbursed psychiatric route identified; off-label ketamine and trial-only classical psychedelics should be treated separately.

  • 4

    Ketamine is not merely research-only in Belgium: it exists inside ordinary medicines law, but not as a broadly reimbursed antidepressant indication.

  • 5

    Belgium's strongest current research signals are psilocybin in addiction and treatment-resistant depression, and ketamine in neurocritical care and disorders of consciousness.

  • 6

    The ecosystem is hospital-led, with relevant nodes in Brussels, Ghent, Leuven and Liege rather than a broad private psychedelic-care market.

Medical Access Snapshot

Belgium has limited medical access rather than legal access to classical psychedelics. Spravato has EU authorisation and a restricted Belgian reimbursement route; ketamine is an authorised anaesthetic used off-label in some psychiatric settings under prescriber responsibility. Psilocybin, MDMA, DMT, mescaline and related classical psychedelics remain trial-only or unavailable for routine care, and no open public psychedelic CUP/MNP was identified in the sources reviewed.

Regulatory Status

Belgium regulates narcotics and psychotropics through the 24 February 1921 law and the Royal Decree of 6 September 2017, with FAMHP acting as the national competent authority and publishing updated annexes and the Narcoreg framework. In the consolidated annexes valid from 29 March 2026, FAMHP Annex IIA expressly lists DMT, LSD, MDMA, mescaline, psilocin and psilocybin. None of those classical psychedelics has general Belgian market authorisation as a medicine. Spravato is centrally authorised in the EU and available in Belgium within medicines regulation, while ketamine is an authorised medicine for anaesthesia rather than an approved antidepressant. Psychedelic clinical trials must proceed through the normal CTIS/FAMHP and ethics route rather than through a general therapeutic exemption.

History of Research in Belgium

Belgium's current psychedelic policy environment is best understood as a medicines-control framework, not a reform framework. The operative legal base remains the 1921 drug law as implemented through the 2017 Royal Decree, which FAMHP continues to update through consolidated annexes. As of the March 2026 update, named classical psychedelics remain in the national psychotropics system, and the official sources reviewed do not show a national move towards decriminalisation or non-medical legal access. # #

The modern Belgian evidence base began earlier with ketamine than with psilocybin. A Belgian phase II trial recorded in EudraCT in 2016, sponsored by UZ Leuven, set out to replicate the efficacy of intravenous ketamine in a Belgian sample and identify biomarkers of response and relapse in major depression and bipolar depression. The trial was completed, and Belgian follow-on work included a 2021 pilot randomised analysis reporting heart-rate findings after a single ketamine infusion. # #

Belgium then became part of the multinational esketamine development programme. Belgian sites participated in key Janssen studies including TRANSFORM-3, and broader long-term or comparative esketamine studies such as SUSTAIN-3 and ESCAPE-TRD. Belgium's first routine psychiatric access route around a psychedelic-adjacent medicine therefore came through mainstream antidepressant development, authorisation and reimbursement rather than through psychedelic-policy reform. # # # #

The classical psychedelic restart appears later and remains small. A 2024 protocol paper described the CHU Brugmann psilocybin-assisted therapy trial for severe alcohol use disorder in Brussels, and public registry material now shows a hospital-based psilocybin programme in treatment-resistant depression at Ghent University Hospital. This is a meaningful step for Belgium, but it still looks like a cautious hospital-based restart rather than a mature national platform. # # #

Brussels and Regional Research Nodes

The clearest regional starting point is Brussels. It combines national regulation and payment architecture with hospital research: FAMHP and RIZIV/INAMI sit there, and CHU Brugmann hosts the country's best-documented psilocybin alcohol-use-disorder programme. Brussels also appears in multinational esketamine development through Belgian trial-site participation. # # # #

Belgium's live ecosystem is no longer only a Brussels story. Ghent has emerged through the PSIHOS-D programme at Ghent University Hospital and a linked UGent implementation project. Leuven remains important through KU Leuven and UZ Leuven's ketamine work in depression and severe brain injury, while Liege's contribution is strongest in consciousness science and neurocritical research rather than psychiatric psilocybin therapy. # # # # #

The relevant actors are FAMHP for medicines and controlled substances, RIZIV/INAMI for reimbursement, CHU Brugmann and Universite libre de Bruxelles for psilocybin addiction research, Ghent University Hospital for treatment-resistant depression feasibility work, KU Leuven and UZ Leuven for ketamine research, and the University of Liege and Coma Science Group for disorders-of-consciousness work. # # # # # #

The ecosystem signal is therefore strongest where regulation, university hospitals and translational neuroscience intersect. Belgium does not yet present as a broad commercial psychedelic-care market; it presents as a compact, methodical, hospital-based research environment with one reimbursed esketamine route and a small but credible classic-psychedelic revival. # # # # # #

Research Focus

Belgium's classic-psychedelic work is presently anchored in psilocybin. The Brussels programme at CHU Brugmann is a phase II randomised study in severe alcohol use disorder, with a protocol published in BMC Psychiatry in 2024 and registry material describing a 30 mg psilocybin arm against a low-dose psilocybin active placebo in an inpatient rehabilitation context. In Ghent, PSIHOS-D is a hospital-based psilocybin feasibility study in treatment-resistant depression at Ghent University Hospital, and an UGent project page points to related implementation work in a residential treatment setting between 2025 and 2026. # # # #

Ketamine research has a broader Belgian footprint and a different scientific orientation. In Liege, the University of Liege and the Coma Science Group are running a controlled programme exploring intravenous subanaesthetic ketamine in post-comatose disorders of consciousness; registry material describes a crossover design, and a pilot human paper was published in 2024/2025. In Leuven, the BIKe trial is an enrolling multicentre study in severe traumatic brain injury testing ketamine as an adjunct to standard sedation, with a protocol paper published in 2025. # # # #

Belgium also has an important legacy role in esketamine. Public registry and publication sources show Belgian participation in pivotal multinational esketamine studies and long-term extensions, including TRANSFORM-3, SUSTAIN-3 and ESCAPE-TRD. That means Belgium has been part of the evidence-generation base for the only psychedelic-adjacent psychiatric medicine now visible in Belgian reimbursement. By contrast, the public Belgian registry footprint reviewed here does not show the same level of live Belgian site activity for MDMA, LSD or DMT therapy trials. # # # #

Future Outlook

Over the next 12-24 months, the most plausible changes in Belgium are evidentiary rather than legislative. The visible psilocybin studies in Brussels and Ghent, alongside ketamine work in Leuven and Liege, are the likeliest sources of near-term change. If Belgian sites publish feasibility, safety or implementation data, Belgium's profile will rise mainly as an investigator-led hospital research node rather than as a first-mover access jurisdiction. # # # # # # #

Regulatory liberalisation looks unlikely over the same period. The official material reviewed shows a standard narcotics/psychotropics control model, continued FAMHP annex maintenance, and no obvious move towards general psilocybin or MDMA treatment pathways outside trials. The more realistic regulatory developments are incremental: additional trial approvals, controlled-substance handling refinements, and better-defined hospital practice around authorised esketamine and off-label ketamine. # # # #

Reimbursement is also unlikely to broaden quickly beyond current esketamine rules. Any future Belgian reimbursement for a classical psychedelic would still have to follow evidence generation, marketing authorisation or a special-access logic, and then a payer decision through RIZIV/INAMI. Belgium is likely to become more interesting scientifically before it becomes materially more permissive for patient access. # #
