The first person in the UK who has died from taking the terrifying new "zombie drug" has been named as a British dad, it has been reported.
Factory worker Karl Warburton, 43, died last May from xylazine, which is used by vets as a tranquilliser for large animals such as horses and cows.
The drug has never been approved for human use as it can cause flesh-rotting sores on takers’ skin.
