In Belgium, cannabis is illegal, but possession of up to 3 grams or one female plant for personal use by adults is tolerated.
However:

  • There is no official right to home cultivation; it remains an offense.

  • Police and justice can intervene, especially with larger quantities or suspicions of trade.

Commercial cultivation in Belgium is always punishable.

Important: Enforcement can differ per region (for example, stricter approach in Flanders than in Brussels).
