Marijuana Laws & Legislation for Leuven – Louvain

As of 2025, cannabis remains illegal in Belgium, but possession of up to 3 grams or one female plant for personal use by adults over 18 has been decriminalized since 2003. While such minor infractions typically result in fines of €120 to €200, possession in aggravating circumstances (such as near schools or involving minors) can lead to harsher penalties, including imprisonment. Despite ongoing discussions, recreational cannabis remains prohibited.

Belgium has a limited medical cannabis program, allowing only specific cannabis-based medications like Sativex and Epidyolex for conditions such as multiple sclerosis and epilepsy. However, broader access to medical cannabis remains restricted, and personal cultivation for medical use is not allowed. CBD products derived from hemp (with less than 0.2% THC) are legal, but strict regulations apply—CBD cosmetics and topical products are permitted, while CBD oils and edibles are largely prohibited. While cannabis laws remain restrictive, Belgium’s decriminalization policies and ongoing debates suggest potential future reforms.
