20 Sep 2019 --- Almost half of cannabidiol (CBD) products currently available on the UK high street contain cannabinol (CBN) or tetrahydrocannabinol (THC). This is according to tests commissioned by CBD producer TTS Pharma and carried out by an independent analytical laboratory, Fera Science Ltd. These findings come as the legality of the burgeoning CBD market in the UK is under question, with TTS Pharma arguing that the health and safety of the consumer should be the highest priority of all companies intending to, or already producing CBD products.
