Hemp (Cannabis sativa) has been cultivated for hundreds of years around the world. Industrial hemp is grown in Europe on a limited basis to produce fiber, but also seeds and oil. Hemp varieties that can be grown for these purposes should be included in the common catalogue of varieties of agricultural plant species in the European Union (EU).
The maximum tetrahydrocannabinol (THC) content, which is the main psychoactive substance, is limited to 0.2% in the EU, while in the US it must be less than 0.3%.
