A dad who was killed when his car left the road had cocaine in his system, an inquest has heard.
A post mortem examination revealed traces of cocaine and diazepam were present in Adam Brennan’s blood when he died.
PC Anthony Powell, an accident investigator with Northumbria Police, said: “It is possible it (the drugs) could have affected his driving.”
The 40-year-old lorry driver was killed after the Vauxhall Astra he was in left the A690, between Houghton-le-Spring and Stony Gate on Friday, September 11th.
The inquest was told tests revealed the Astra’s tyres were under inflated and could have made the car more difficult to handle.
PC Powell said statements taken from witnesses in the area at the time of the crash said there was no other vehicle involved in the collision.
He said witnesses also supported the theory that Mr Brennan had been travelling above the 50mph speed limit on the road, which runs between Durham and Sunderland.
The post mortem examination was conducted by Dr Mona Jain, who concluded the cause of death was head and chest injuries.
Karin Welsh, assistant coroner of Sunderland, recorded a verdict of accidental death.

But officials have said that Mrs Sandiford may escape the death penalty because she helped catch three other members of a suspected drug trafficking ring.
Three Britons and an Indian man were also arrested.
