On 28 June, the Pharmaceutical Journal reported that confusion around the legal threshold for tetrahydrocannabidol (THC) in cannabidiol oil has led the Royal Pharmaceutical Society to request “clear guidance” on the matter. It has written to the home secretary calling for “clear guidance” on the permissable level of psychoactive tetrahydrocannabidol (THC) in cannabidiol (CBD) oils. A recent report found that almost half of the commercially-available CBD oil it tested contained detectable amounts of THC, making them “technically illegal within the UK” – 45% of products tested had “measurable levels of THC”, with a mean content 0.04%. CBD is not psychoactive and so is not a controlled substance. It may be sold through retail outlets as long as no medical claims are made for a product.
