Weed is partly legal in Luxembourg. Since July 2023, adults have been allowed to grow up to four cannabis plants per household at home and use cannabis in private.
Carrying or using it in public is still an offence: up to 3 grams brings a fine, and more than 3 grams is a criminal offence. There is no legal place to buy cannabis. This guide explains Luxembourg’s cannabis laws, home growing, the public limits, medical cannabis, CBD and the rules for visitors.
Is weed legal in Luxembourg for recreational use?
Partly. The Law of 10 July 2023, in force since 21 July 2023, legalised growing cannabis at home for personal use by adults. It amended Luxembourg’s 1973 drug law rather than creating a full legal market.
What changed is private use. Adults may grow cannabis at home and consume it there. What did not change is the public space: carrying or using cannabis in public, at work, in schools or around minors remains prohibited.
There is also no legal way to buy cannabis. No regulated sales market exists, so cannabis shops and coffee shops remain illegal.
Can you grow weed at home in Luxembourg?
Yes. The 2023 law allows up to four cannabis plants per household, not per person. The plants must be grown at the home or usual residence, by adults, from seed only.
They must not be visible from the public highway, according to the health ministry’s guidance. Growing more than four plants, or growing them anywhere other than the home, is a criminal offence with penalties of up to five years in prison and large fines.
What are the penalties under Luxembourg weed laws?
Penalties under Luxembourg weed laws depend on how much you carry in public and where. Up to 3 grams in public is still an offence, but it is dealt with by a fine.
For up to 3 grams, police can impose a fixed warning of 145 euros, or the case can result in a police fine of 25 to 500 euros. Above 3 grams, possession is a criminal offence carrying eight days to six months in prison and a fine of 251 to 2,500 euros.
Offering or supplying cannabis to minors is treated much more severely, with six months to two years in prison and fines of 500 to 25,000 euros.

Is medical marijuana legal in Luxembourg?
Yes. Medical cannabis has been legal in Luxembourg since a law of 20 July 2018, which came into force in August 2018. It is reserved for exceptional and limited cases.
The health authorities list conditions such as chronic pain, nausea caused by chemotherapy and spasticity in multiple sclerosis.
Is CBD legal in Luxembourg?
CBD is legal in Luxembourg in some forms but not others. According to a 2022 health ministry leaflet, hemp varieties with less than 0.3% THC are permitted. Smokable hemp products must stay under that limit and be declared to the health directorate.
CBD food and food supplements are a different matter. The same leaflet treats them as unauthorised novel foods, which means they cannot be marketed. Check what kind of product you are buying.
Can you smoke weed in Luxembourg as a tourist?
Not in public. The home-growing rules are tied to a residence, so a visitor has no legal way to obtain cannabis in Luxembourg, and buying it from a dealer is illegal.
The public-space rules apply to everyone. Using or carrying up to 3 grams in public brings a fine, and more than 3 grams can bring a criminal case.
Official travel advice is cautious. The UK Foreign Office warns that illegal drugs, including cannabis, carry severe penalties. The US State Department says penalties for drug possession, use or trafficking can include long prison sentences and heavy fines.
The bottom line on cannabis in Luxembourg
Weed is partly legal in Luxembourg: adults can grow up to four plants per household and use cannabis at home. Public use and possession remain offences, with a fine for up to 3 grams and criminal penalties above that.
Medical cannabis is legal for limited cases, while CBD foods are not authorised. With no legal place to buy, visitors should not expect to use cannabis in Luxembourg.
