Luxembourg Cannabis Laws: Home Use, Four-Plant Limit and Restrictions
General information only--not legal advice or a determination that anyone's conduct is lawful. Check current law and official sources before acting.
The short answer
Luxembourg has a limited home-use and home-cultivation framework, not unrestricted retail legalization. The government Health portal says an adult may cultivate up to four cannabis plants per domestic community at their home or usual residence, using seeds only. Plants must not be visible from a public road. Adults may consume cannabis cultivated at home or their usual residence.
A "domestic community" means people living together in a common household and sharing a common budget. The four-plant ceiling applies to that community, not each adult separately.
Conditions for home cultivation and use
Cultivation must be carried out by an adult, at the home or usual residence, exclusively from seeds, and limited to four plants per domestic community. These conditions do not authorize buying cannabis plants, retail supply, or sharing home-grown cannabis outside the domestic community.
What remains restricted
The Health portal says public consumption and consumption outside the place of cultivation are prohibited. It also identifies public possession, transport, and acquisition as prohibited; cannabis may not be shared with people outside the domestic community. Consumption by minors, or by adults in the presence of minors or together with minors, is prohibited.
The Health portal separately says driving under the influence remains prohibited and describes the road-traffic THC threshold. This article does not assess impairment or whether anyone may drive. Consult current law or official authorities for enforcement details.
