A mum-of-two was killed after taking a cocktail of drink and drugs and driving two miles the wrong way on a motorway, an inquest heard.
Georgina Coombs, 38, crashed into an innocent motorist after rowing with guests at a house party and storming out.
She drove into oncoming traffic on the M4 before ploughing into driver Dale Jones who was left with life-changing injuries.
The inquest in Newport, South Wales, heard Mrs Coombs was two and a half times over the drink-drive limit and had taken cocaine at the party.

Gwent Coroner Caroline Saunders, said: 'Her partner followed her but Georgina had already driven away from the house in her Vauxhall Astra by the time he got outside.'
Gwent Coroner Caroline Saunders, said: 'There was a disagreement between the party attendees which resulted in Georgina leaving the house at approximately 10.20pm, apparently without telling anyone she was going.
'Her partner followed her but Georgina had already driven away from the house in her Vauxhall Astra by the time he got outside.'
The inquest heard police plotted Mrs Coombs' journey through eye-witnesses, CCTV and dash cam footage.
The coroner said: 'Georgina drove onto the West bound carriageway of the M4 but she is driving in the wrong direction against the flow of traffic.
'Georgina continued along the M4 for 2.8km. She passes several cars that swerve out of her way and flash their lights.
'It appears that at one point Georgina attempted to avoid the oncoming traffic.
'It is hard to understand why she did not realise her mistake and pull onto the hard shoulder.'
The coroner said Mrs Coombs, of Cwmbran, South Wales, had consumed a 'considerable amount of alcohol' before crashing into Mr Jones's black BMW on 22 February last year.
The coroner recorded a narrative verdict that Mrs Coombs died of multiple injuries due to a road traffic collision

The coroner added: 'Georgina had also used cocaine prior to her death.
'I am of the opinion that the high level of alcohol was the reason that Georgina was driving in this dangerous and fatal manner.'
Her family said in a statement at the time: 'Georgina was involved in a tragic accident which has left two children behind and a huge hole in the family who are truly devastated.
'She will be truly missed by everyone who knew her.'
