D'après le catalogue européen des ingrédient nouveaux (Novel Food):
There was a request whether this product requires authorisation under the Novel Food Regulation. According to the information available to Member States' competent authorities, this product was not used as a food or food ingredient before 15 May 1997. Therefore, before it may be placed on the market in the EU as a food or food ingredient a safety assessment under the Novel Food Regulation is required.
D'après notre compréhension, le cannabidiol est un ingrédient nouveau au sens du Règlement (CE) n° 258/97 du Parlement européen et du Conseil du 27 janvier 1997 relatif aux nouveaux aliments et aux nouveaux ingrédients alimentaires
Toujours d'après ce même catalogue on trouve pour Cannabis Sativa :
In the European Union, the cultivation of Cannabis sativa L. varieties is permitted provided they are registered in the EU’s ‘Common Catalogue of Varieties of Agricultural Plant Species’ and the tetrahydrocannabinol (THC) content does not exceed 0.2 % (w/w). Some products derived from the Cannabis sativa plant or plant parts such as seeds, seed oil, hemp seed flour, defatted hemp seed have a history of consumption in the EU and therefore, are not novel. Other specific national legislation may restrict the placing on the market of this product as a food or food ingredient in some Member States. Therefore, it is recommended to check with the national competent authorities
