Schedule 21 of the Deregulation Act 2015 has amended The Poisons Act 1972 to change the way in which poisons and chemicals can be sold through pharmacies. There will now be a common system for regulating the possession and supply of non-medicinal poisons and explosives precursors. The public can still buy regulated poisons and chemicals from pharmacies but someone using, acquiring, possessing or importing the substance must have a licence from the Home Office. Pharmacies can supply these items if they keep appropriate records and comply with new labelling requirements. Pharmacists also have a duty to report suspicious transactions. The Royal Pharmaceutical Society has produced a guide to help pharmacists with the change in law.
