A teenager who had a 'troubled upbringing' and had been in and out of care died after taking a cocktail of drugs while visiting his biological mother in Manchester, an inquest heard.
Lewis Garner, known as Lewis Evans, was found by his mum Sonia Mitchell in bed at her home in Gorton.
Ms Mitchell told an inquest how she tried to resuscitate the 17-year-old before calling an ambulance.
Lewis was pronounced dead shortly after.
Tests showed he died of broncho-pneumonia having taken multiple substances - including heroin, cocaine and MDMA in October 2014.
Manchester Coroners' Court heard Lewis, the youngest of five siblings, was in and out of care from a young age.
He was in foster care from around the age of two and was adopted at seven by a family in Blackburn.
The court heard his relationship with his adoptive parents broke down when he was around 14 and he told them he wanted to go back to his biological family.
Lewis then stayed with various relatives before being put in a children's home in Blackburn.
He spent time living with his mother and his brother, before eventually settling with his biological father in Guernsey.

When he was adopted, Lewis became the responsibility of the Blackburn council, having previously been dealt with by Manchester town hall.
Susan Butlin from Manchester council told the court Lewis and his siblings were re-homed following concerns over alleged neglect.
"There had been concerns around neglect and some other issues in the house," she told the court.
"On one event [Lewis' father] was alleged to have shot one of the children with an air pistol.
"There were concerns that the parents were alcohol and drug users and concerns about domestic abuse."
Ms Mitchell told the inquest she tried to help her son reconcile with his adoptive family.
"I was trying to ensure what would be best for my son," she said.

"Even though I would have loved to have had him back, Lewis had been given a different side of life."
The inquest was told Lewis had a prolonged history of drug abuse.
Ms Mitchell said he had been taking drugs in the days before he death.
"He said he had been partying with his friends," she said.
"I think he smoked cannabis, he said that he had smoked weed at the party, but there were no other drugs that he told me about.
"He looked a little bit wasted."
The night he died, Lewis went to bed after returning from a night out with friends.
The court heard that when Ms Mitchell went to check on him around around lunchtime the next day, she found him unresponsive in bed.
Elizabeth Manion, a worker from Blackburn council, said Lewis' drug use was a concern when he was just 14.
She said: "He mainly kept going missing.
"I know that obviously we were trying to work with him on his drug misuse. The drugs service allocated a worker to try and work with him."
Assistant coroner Anthony Mazzag gave a conclusion of a 'drug-related death'.
"Lewis had a problematic and troubled upbringing, and this was the reason he was taken into care," he said.
"He turned to using drugs... social services records support that conclusion.
"That became a particular problem after the adoption broke down. Drug use may well have started in Blackburn.
"Medical evidence on his lungs shows he was using significant amounts of cannabis."
