Legal status of cannabis in the European Union (as of 25 September 2026)

“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.”]
