A dad-to-be stabbed himself in the neck with a piece of glass after taking a cocktail of cocaine, legal highs and alcohol.

Lifeguard Jake Harris, 21, had been clubbing in Manchester and went back to a friend's flat where he snorted cocaine and drank vodka until 10am, an inquest heard.

While at the flat Jake and pal Steven Higgins took strips of what they believed to be hallucinogenic LSD.

But just hours later Jake, from Rochdale, was heard to say: “I want it to stop”.

Moments later he threw himself against the full length apartment window several times.

He then smashed a wine glass and stabbed himself with it.

Friend Heather Turner, whose flat they were at in Spectrum Apartments on Blackfriars Road, Salford, sobbed as she told the inquest: “He stabbed himself repeatedly with the glass.”.

Police and paramedics were called but by the time Jake was admitted to Salford Royal he had already gone into cardiac arrest.

The following day, on May 28 this year, doctors told family members that Jake would not be able to survive without being on life support.

That night treatment was terminated and Jake never woke up.

The inquest heard how police found door handles covered in blood and patches of blood on the carpet and in the corridor.

Jake, who worked at Whitworth Leisure Centre in Rochdale and lived with his grandmother, had been clubbing that night at the Basement club in Manchester with his father Luke Harris.

At the end of the night Jake and Steven went to Heather's flat to carry on partying.

The inquest, at Bolton Coroners Court, heard how at around 9am Jake and Steven went to the corner shop to buy more alcohol.

Steven found strips of what he believed to be hallucinogenic LSD in his wallet, which were bought with the intention of 'trying them out before going to Glastonbury'.

Describing Jake as 'an entertaining party guy' Steven told the inquest: “We all had a good laugh. He was in very good spirits.”

The inquest was told how he had recently learned how an ex-girlfriend had fallen pregnant with his child.

“We could see in the back of his mind that something was bothering him,” Steven said.

In a statement, Jake's mother, Jane Harris-Cookney, described him as a 'much-loved son and a friend to many'.

She said: “He had the ability to light up a room when he came in.

“There is a big gaping hole in our hearts.”

She told of how Jake had begun taking recreational drugs two years earlier.

He had once “smashed up my [his mother's] house in a drug induced rage”.

Mrs Harris-Cookney told of how two to three months before his death Jake had been taken to hospital after his throat swelled following an adverse reaction to drugs.

His mother told of another instance when he had 'taken six to eight hours to come down' and Jake had said: “I don't want to wake up".

Mrs Harris-Cookney told of how Jake suffered from heart condition Ductus

Arteriosus which can strain the heart and increase blood pressure.

Analysis of the strips later revealed that they were in fact legal-high 251-NBOME also known as N-Bomb.

The high was legal until 10 June 2013 when the drug was classed illegal. Risks include paranoia, confusion and powerful hallucinations.

The inquest continues.
