A dad-of-one was killed on his 27th birthday after crashing his car on his way home from a party where he had taken cocaine and drunk brandy.
Tesroi Beckford lost control of his Vauxhall Astra in Redditch, Worcestershire in March this year.
An inquest at Worcestershire Coroner's Court heard he was returning from a celebration with friends when his car clipped a kerb, crossed the carriageway and careered into a lamppost before overturning.
Another driver told the inquest Mr Beckford overtook him at a speed between 90 and 100mph.
Soon after, the driver came across the overturned car and called the emergency services, but Mr Beckford was declared dead at the scene.
A friend who was with him that night told West Mercia Police: "Tesroi had been drinking from a bottle of brandy and adding coca cola. He drank from the bottle but shared it with friends."
Friends described Mr Beckford as being “really high, off his kite and really happy” on his birthday and said he later decided to drive home and accelerated away, leaving them to continue celebrating.
Due to difficulties in gaining a blood sample, a test for alcohol levels could not be done but toxicology tests found levels of cannabis and cocaine in Mr Beckford's system, although they were not particularly high.
Pathologist Dr Kin-Chung Wu said it wasn’t possible to say whether alcohol or drugs had an effect on Mr Beckford's driving.
Police investigations found that the crash came after a sweeping left hand bend. The road was in good order, there were street lights and there was dry and fine weather that night.
Officers found there had been “high speed impact” in the collision and an examination of Mr Beckford’s car found mechanical issues such as the tyre pressure being higher than recommended, the catalytic converter removed, and breather pipe moved to the front wing.
The cause of death was given as multiple fatal injuries caused by a road traffic collision.
The coroner recorded a conclusion of death due to a road traffic collision.
