Before discovering the healing properties of cannabis, its use was mainly connected to industry. Although some countries (especially in Europe) have adopted a distinction between the varieties of cannabis that, generally being used in the industrial sector, do not fall within the scope of laws on psychotropic substances, not all countries have made this distinction.
In the European Union, the cultivation of industrial cannabis (hemp) is permitted provided the variety is registered in the EU’s ‘Common Catalogue of Varieties of Agricultural Plant Species’ and the THC content does not exceed 0.2%. This measure has been taken with the aim of encouraging cultivation.
Industrial cannabis usually contains only traces of THC, while CBD is present. Not all countries have clear regulation on CBD.
