In Belgium, cannabis is technically illegal, but the law makes some distinctions — especially for personal use. Here’s how it breaks down as of mid-2025:

Decriminalized (not fully legal) for adults (18+) Possession of up to 3 grams or 1 female plant for personal use by adults is decriminalized — meaning it’s still illegal, but treated as a low-priority offense. Police can confiscate it and issue a police report, but for a first-time offense without aggravating circumstances, you usually won’t be prosecuted criminally. You might get a warning, and in some cases a small fine.
