Legislative Background
Belgium decriminalized possession of small amounts (up to 3 grams) for personal adult use in 2003, classifying it as a low-priority administrative offense rather than a criminal one. Medical cannabis access has been available through regulated pharmaceutical channels and specialist prescriptions for qualifying conditions.
Law Enforcement
On warm summer evenings in student-heavy Leuven, you could smell weed all over town. Police still tried to stop public smoking. I preferred somewhere private or away from the crowds in a park or the woods.
Where to Buy Marijuana
There were plenty of bars and offers around the Oude Markt, but the police department was close by. Students sometimes knew where to look if the market didn’t work out.
Marijuana Prices
€4–5 at the low end and €7–8 a gram for good weed.
Types of Marijuana
Local indoor and outdoor weed, plus plenty of shop weed said to come from the Netherlands.
