Is cannabis legal in Luxembourg?

Is cannabis legal in Luxembourg? Yes, but legal cannabis in Luxembourg is confined to a very specific perimeter: at home, never in the street. In 2023, the Grand Duchy became one of the few countries in the EU to authorize home cultivation, right after Malta. Yet, cannabis in Luxembourg remains impossible to find legally for anyone who does not grow it themselves. At Tealer420, we took a close look at this model because it is one of a kind and often poorly summarized. Here is what is permitted and where the sticking points are.

Cannabis in Luxembourg: what the law allows at home

The law of July 10, 2023, came into force on July 21, 2023. It does not create a market; it simply opens up the private sphere. An adult aged 18 or older may consume in their home or habitual residence, on one condition: never in front of minors.

A surprising detail: there is no weight limit in grams for what you keep at home, as long as it comes from your own harvest. The limit applies to the number of plants, not the weight of the jar.

Growing in Luxembourg: the rules of the game

This is the heart of the reform. To grow legally, you must check all the boxes:

• 4 plants maximum per household;
• only from seeds;
• at home or your habitual residence, and nowhere else;
• plants not visible from the public road.

Seeds can be purchased legally in shops, online, or via import. If you want to understand what growing involves in practice, we detailed the basics in our guide on how to grow weed, keeping in mind that in France, even a single plant remains an offense.

The classic trap: the 4 plants apply to the household. Four roommates are not entitled to sixteen plants, but to four in total. Exceeding this number or growing outside the home is punishable by 8 days to 5 years in prison and/or a fine of €500 to €250,000.

In the street: the €145 joint

Step outside your home, and the legalization stops immediately. In public spaces, possessing, consuming, transporting, or buying cannabis remains prohibited:

• Up to 3g: a simple contravention, settled by a €145 fixed penalty warning or a fine of €25 to €500.
• More than 3g: a criminal offense, punishable by 8 days to 6 months in prison and/or a fine of €251 to €2,500.

Smoking in a park in Luxembourg City therefore costs €145, while the same herb, grown and consumed at home, is perfectly legal. That is the whole paradox of the model.

Why there is nothing to buy

The initial project provided for much more: state-regulated production and retail outlets. This was abandoned in 2021, and the CSV-DP government that took office in late 2023 has not revived it. We have found no sources announcing a new reform in 2025 or 2026.

As a result, there are no dispensaries, no coffeeshops, and no cultivation clubs either, unlike in Malta or Germany. Sales remain suppressed by the 1973 law on narcotics.

Cross-border commuters and tourists

On paper, the law does not reserve rights only for residents. But without legal sales, visitors have no way to obtain anything in compliance with the rules. And if you live on the French side, in Thionville, Longwy, or elsewhere in Lorraine, bringing cannabis back across the border remains a customs and criminal offense in France.

The same applies on the road, with a zero-tolerance policy that did not change with the reform: starting at 1 ng/ml of THC, driving is punishable by 8 days to 3 years in prison and/or a fine of €500 to €10,000.

Key Takeaways

Luxembourg has legalized adult use, but only within four walls. You can grow four plants per household and consume at home; you cannot buy, smoke outside, or drive after consuming. It is a model of pure home cultivation, without a market or clubs, distinguishing it from its neighbors, as shown in our European overview.

Consumption of illicit cannabis remains prohibited in France.
