Police are issuing warnings about a deadly type of ecstasy tablet after two men from South Ribble were taken to hospital.
It is believed that they had taken a green tablet, thought to be a type of ecstasy.
The incident took place on Friday, June 28, when both men were out socialising and they were taken to the Royal Preston Hospital.
Both have since been released.
Over the past month, eight people across Britain have died as a result of taking similar described tablets and detectives in Lancashire are warning people not to experiment with the drug.
Detective Chief Inspector Neil Ashton from Lancashire Police said: “Whilst the police and the Health Protection Agency cannot directly link the deaths across the country to the incident here in Lancashire, there is a clear danger to taking illicit drugs.
“We are warning people who are looking to buy or who are taking these drugs to consider the significant consequences as it could end up in death.
“An investigation is underway to establish the source of these tablets and those who are supplying them. We would appeal to anyone with information to come forward and contact us.”
Anyone with information is asked to call Lancashire police on 101.
