A footballer terrified of the dentist accidentally killed himself with painkillers after refusing to get treatment for an excruciating toothache, an inquest has heard. Jaye Milner, 24, desperately took the potent drug Fentanyl in a bid to stave off the pain of a four-year tooth abscess, unwilling to go to the dentist to get it fixed. But the promising young sportsman, from Barnsley, South Yorkshire ended up taking too much of substance and was found dead in June last year. Jaye Milner (pictured with his father), 24, desperately took the potent drug Fentanyl in a bid to stave off the pain of a four-year tooth abscess The promising young sportsman (pictured left and right with his father), who graduated from Manchester Metropolitan University, ended up taking too much of substance and was found dead in June last year An inquest into his death held in Sheffield heard warnings from coroner Prof Robert Forrest, who noted the dangers of the 'unpredictable drug' - a powerful opioid used to treat severe pain. And today, his grieving father Tim, 52, spoke out in a bid to warn others about the deadly and little-known synthetic drug, which is considered to be 50 times stronger than heroin. He told The Sun: 'He couldn't stand the dentist. He would go to get antibiotics for a temporary fix but he couldn't bear to undergo surgery. 'After he died, I found out he had been using chewable Fentanyl patches. He probably thought that it was helping him but it is that that's killed him.' Jaye (pictured with his father), who played football against Manchester City star John Stones as a schoolboy, was found with an amount of the drug 'at a level likely to kill'. At the inquest, pathologist Prof Kim Suvarna also the dangers of the drug (stock image), saying: 'Fentanyl can be incredibly powerful and can kill.' Health Secretary Matt Hancock last month that packaging on common medications such as morphine or fentanyl will now have to carry a warning informing patients about the risk of addiction Jaye, who played football against Manchester City star John Stones as a schoolboy, was found with an amount of the drug 'at a level likely to kill'. He was also found with smaller traces of other recreational drugs. With the coroner recording a verdict of accidental death, saying: 'I believe that he may not have realised he was taking a potentially lethal dose of Fentanyl.' What is fentanyl and why is it so dangerous? Fentanyl was originally developed in Belgium in the 1950s to aid cancer patients with their pain management. Given its extreme potency it has become popular amongst recreational drug users. Between late 2013 and early 2015, more than 700 deaths were attributed to fentanyl and related substances in Australia. Drug overdoses killed more than 72,000 people in the US in 2017 – a record driven by fentanyl. While around 300 fentanyl deaths have been recorded in England and Wales since 1993. It is often added to heroin because it creates the same high as the drug, with the effects biologically identical. But it can be up to 50 times more potent than heroin, according to officials in the US. Deaths tied to fentanyl and related drugs doubled in 2016, to more than 19,000. In America, fentanyl is classified as a schedule II drug - indicating it has a strong potential to be abused and can create psychological and physical dependence. Other schedule II drugs include Vicodin, cocaine, methamphetamine, Adderall, Ritalin and oxcodone. At the inquest, pathologist Prof Kim Suvarna also warned of the dangers of the drug, saying: 'Fentanyl can be incredibly powerful and can kill.' Now his devastated family are now desperate to warn others about the the drug. The drug was originally developed in Belgium in the 1950s to aid cancer patients with their pain management.

Last year it was revealed that the singer Prince had an an 'exceedingly high' concentration of fentanyl in his body when he died. Public data released six weeks after his death showed he died of an accidental overdose. Health Secretary Matt Hancock last month that packaging on common medications such as morphine or fentanyl will now have to carry a warning informing patients about the risk of addiction. Dependence on the drug can have devastating consequences for the user. He said: 'I have been incredibly concerned by the recent increase in people addicted to opioid drugs. 'Painkillers were a major breakthrough in modern medicine and are hugely important to help people manage pain alongside their busy lives – but they must be treated with caution. 'We know that too much of any painkiller can damage your health, and some opioids are highly addictive and can ruin lives like an illegal drug.' A Just Giving page has now been set up for Jaye, in which a friend writes: 'A fun loving bubble cheeky chap as you all know, loved life to the max and a true friend to many.' It has a target of £5,000 and has currently raised more than £3,400 from a total of 105 supporters. All rights reserved for this news site dailymail and under his responsibility
