Documentation

Cannabis remains ILLEGAL — adult (18+) possession of up to 3 g or one female plant is the lowest prosecution priority (a simplified police report, in practice a €120–200 fine, no arrest absent aggravating circumstances), but this is tolerance/depenalization, NOT decriminalization or legalization. Aggravating circumstances or more than 3 g trigger criminal prosecution; for minors all cannabis possession is always criminal. Medical cannabis means authorized cannabis-based medicines only (e.g. Sativex) by prescription plus pharmacist CBD preparations — no flower. Importing cannabis (even from the Netherlands) is a separate, more serious offence. [recommendation] An April 2024 parliamentary report recommended a new cannabis framework — not law. Carry any controlled medicine with its prescription and confirm requirements with your embassy before travel.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Belgium’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
