Northumbria Police are warning the public about the dangers of using legal highs after three teenagers were taken to hospital after using a herbal incense over the weekend.
The teenagers from the Blyth area started vomiting blood after taking Clockwork Orange Herbal Incense.
Officers are now trying to find out where the substance came from.
"We want people to be aware of the dangers of taking drugs, including so called "legal highs".
"I would like to stress that the use of legal high drugs is not safe and can kill or have a devastating impact on people's health.
"These substances often contain potentially dangerous chemicals.
"Anyone who misuses drugs, prescribed or non-prescribed, is putting their life at risk and people should also be aware that this risk is significantly increased if mixed with alcohol.
– Superintendent Alan Veitch, Northumbria Police
"We are working to identify and visit premises selling these substances and will take any action necessary to ensure the safety of the public.
