Safe daily limit of cannabidiol CBD cut by regulator

UK food regulators have lowered the recommended safe daily dose of cannabidiol (CBD), a cannabis extract present in many different High Street products, including drinks and snacks.

The Food Standards Agency says the advice is precautionary, following concerns long-term use might cause liver and other health problems.

Adults are being advised to have no more than 10 milligrams of CBD a day.

The previous recommended safe daily dose, from 2020, was 70 milligrams.

And the FSA is warning some products available in shops and online contain more than 10 milligrams of CBD per serving, which is about four to five drops of 5% CBD oil.

FSA chief scientific advisor Prof Robin May, said: "The more CBD you consume over your lifetime, the more likely you are to develop long-term adverse effects, like liver damage or thyroid issues.

"The level of risk is related to how much you take, in the same way it is with some other potentially harmful products such as alcoholic drinks."

Two independent committees reviewed the scientific evidence, including data submitted by manufacturers of CBD products.

The FSA, which has been regulating the CBD market since 2019, says there appears to be no "acute safety risk" from consuming more than 10 milligrams of CBD a day but regular consumption above this level could pose health risks.

Derived from cannabis but without psychoactive properties, CBD is sold in some pharmacies and health-food shops as a supplement and used to treat conditions such as pain or insomnia.

Certain groups - including children, pregnant women and people taking other medications - are advised not to use CBD.

The Association for the Cannabinoid Industry said it would examine the evidence behind the FSA recommendations.
