1. What the law is
Cannabis gets a police warning in Belgium for small personal amounts. Psilocybin gets none. Article 2bis of the Law of 24 February 1921 makes possession of a psychotropic substance punishable by three months to five years in prison plus a fine, and a judge may route a personal-use case into probation instead, but nothing lifts psilocybin out of the criminal law.

Psilocybin is illegal in Belgium.
Are magic mushrooms ("shrooms") legal in Belgium?

Every change we have made to this record, dated, corrections included. Nothing changes silently.
Belgium's entry pointed at the wrong article for the probation route open to people caught with drugs for their own use. It is article 9, not article 9bis, and the entry now says so. The penalties are unchanged.
Belgium was listed as decriminalized and it is not. The 1921 law itself puts possession at three months to five years in prison, so the status was corrected to illegal.
