The Law of 27 June 2023, in force since 21 July 2023 and still applicable in 2026, authorises adults to cultivate up to four cannabis plants per household grown from seed, and expressly permits trade in cannabis seeds with no limit on quantity or the THC content of the parent variety. Seeds may be bought in shops, ordered online or imported, provided packaging is labelled with the producer's details, seed count and a health warning. Transfer of harvested cannabis remains prohibited, but acquiring or passing on seeds themselves is lawful for adults. Agricultural hemp cultivation continues separately under EU rules using certified common-catalogue varieties.
