A 64-year-old man from Blackpool has been arrested on suspicion of supplying drugs and is currently in custody.
Detective Inspector Abi Finch-Hall, of Blackpool CID, said: “One person has died and another is seriously ill in hospital and my thoughts are with their loved ones at this time.
"An investigation is ongoing to try and establish exactly what the men had taken which caused them to become unwell and whether there is more of the drug in general circulation.
“We would obviously prefer that people did not take any illegal substances, but realistically we are advising drug users that while our enquiries continue to establish what these men have taken to seek immediate medical attention if they notice any different symptoms or start to feel unwell following taking drugs.”
