Legal status of cannabis in the European Union (as of 25 September 2026)
- The EU has no single cannabis law: it sets a common framework for hemp farming, trade and drug trafficking, while recreational use is regulated by each Member State.
- CBD lawfully produced in one Member State may in principle be sold in another; a national ban is allowed only if it is suitable to protect public health and does not go beyond what is necessary. The Court held that such CBD is not a narcotic drug under the 1961 Single Convention (Articles 34 and 36 TFEU, Case C-663/18 Kanavape, paras 76 and 96).
- Industrial hemp qualifies for CAP direct payments only if the THC content of the variety does not exceed 0.3 % (Art. 4(4) Regulation (EU) 2021/2115); THC control methods are set by the Commission (Art. 60(4)(a) Regulation (EU) 2021/2116).
- Member States may restrict how hemp is grown, for example ban indoor hydroponic cultivation, if the restriction is suitable and proportionate for protecting public health (Case C-793/22 Biohemp Concept, 4 October 2024).
- Member States must make intentional unlawful cultivation of cannabis plants and drug trafficking a criminal offence (Art. 2(1)(b) Framework Decision 2004/757/JHA, as quoted in Case C-271/23).
- Rules on recreational cannabis differ widely: Germany allows adults to possess up to 25 g in public, 50 g at home and three plants (§ 3 and § 9 KCanG), while in Czechia personal use becomes a criminal offence only above 5 plants, 200 g at home or 50 g elsewhere, and plants with up to 1 % THC are excluded (§ 285 Czech Criminal Code).
“Články 34 a 36 SFEU musí být vykládány v tom smyslu, že brání vnitrostátní právní úpravě, která zakazuje uvádět na trh CBD, který je legálně vyprodukován v jiném členském státě, v případě, že je extrahován z celé rostliny cannabis sativa, a nikoli pouze z jejích vláken a semen, ledaže je tato právní úprava s to zaručit naplnění cíle ochrany veřejného zdraví a nepřekračuje meze toho, co je k dosažení tohoto cíle nezbytné.”
[Translation: “Articles 34 and 36 TFEU must be interpreted as precluding national legislation which prohibits the marketing of CBD lawfully produced in another Member State when it is extracted from the Cannabis sativa plant in its entirety and not solely from its fibre and seeds, unless that legislation is appropriate for securing the attainment of the objective of protecting public health and does not go beyond what is necessary for that purpose.”]
