The government has no intention of legalising the use of cannabis for recreational (non-medical) use.
However, the use of CBD oil is NOT illegal.
Possessing cannabis (drug form with THC) IS illegal, whatever you’re using it for. That includes medical use unless it has been prescribed for you.
Under the Misuse Of Drugs Act 1971, most cannabinoids (including THC) are illegal. CBD however, is not. In fact, if you are using CBD for a medical purpose and it is extracted from EU-approved industrial hemp, then you are not technically stepping outside the law. For a manufacturer to stay within the law, all CBD oil must contain less than 0.2 per cent THC.
