First and foremost, THC is an important factor to consider when it comes to cannabis oil being legal in the United Kingdom. It is the compound responsible for causing the “high” often linked to cannabis use. It is found in CBD and is illegal in the UK. Thus, even though cannabidiol is permitted, there are some strict restrictions placed over its THC concentration levels. At present, CBD oil in the United Kingdom can have a maximum THC concentration level of 0.2 percent. Anything higher than that is illegal and its use is forbidden in the country.
Third, CBD is not categorized as a controlled drug in the Misuse of Drugs Act 1971. Additionally, it is not in the Psychoactive Substances Act 2016. Therefore, provided that no medical claims are made and that it is openly sold as a food supplement, then it is remains legal to possess, sell, and purchase.
