A man from Pembroke Dock passed away due to there being a high level combination of prescribed and non-prescribed medication in his system, a coroner's inquest heard last week.

Thirty-six-year-old Martin John Williams, of Hamilton Court, who was a carer for his disabled wife, died on May 17 of last year.

Speaking at the inquest into his death, held at Milford Haven Town Hall, coroner's officer for Dyfed Powys Police, Jeremy Davies, said that Mr. Williams had completed a drugs rehabilitation programme back in 2013, as he had an addiction to Diazepam.

"He was a regular cannabis smoker and often drank cider before going to bed," Mr. Davies told the inquest.

"On the night before his death, he and his wife Sian had a visit from friend Barry Wagner, who Mr. Williams drank some cider with.

"At 8.45 pm, Mr. Williams left the house to attend to a friend's dogs which he was looking after nearby, but when he returned home, his wife noticed he was not quite with it and after questioning him, he admitted that he had taken the drug Oramorph.

"He went to sleep that night and at 9 am the following morning, Mr. Wagner, who had stayed over, told Mrs. Williams that he could not get a response out of her husband.

"Paramedics attended and performed CPR, but pronounced life extinct that morning," added Mr. Davies.

HM Coroner for Pembrokeshire, Mr. Mark Layton, read out a statement from Mrs. Williams in which she said that the couple, who had two daughters, lived a normal, happy life.

She said that her husband was a regular user of cannabis and was prescribed Co-codamol for nerve damage that had been caused to his cheek.

"Knowing her husband's history, when she discovered that he had taken Oramorph, she was furious with him and said 'what are you taking that stuff for, it will kill you'," said Mr. Layton.

A post-mortem report revealed that Mr. Williams had died from unnatural causes, through cardiorespiratory failure caused by the combined effect of a high level of Morphine, Diazepam and Codeine in his blood.

Coroner Mr. Layton recorded a conclusion that Mr. Williams died a drugs related death.

"He had taken the drugs, but I'm sure that he didn't think for one minute that they would result in his death," he said.
