Greening was working at Smooth Radio and BBC7 before his death
Former BBC Radio 1 Breakfast DJ Kevin Greening died from a drugs overdose after taking part in a gay bondage session, an inquest has heard.
The body of the 44-year-old was found by police in a flat in Wandsworth, south London, in December last year, Westminster Coroner's Court heard.
Coroner Paul Knapman recorded a verdict of misadventure.
Greening co-hosted Radio 1's breakfast show from 1997 to 1998 with fellow DJ Zoe Ball.
Mr Knapman said: "He was found dead having indulged in unorthodox sexual behaviour involving restraint equipment and illegal drugs."
On the day he died, he had been in a leather sling attached to scaffolding in the bedroom of the flat occupied by his boyfriend Sean Griffin, the inquest heard.
At the time, the inquest heard, Mr Greening was still wearing a rubber suit and had cling film and "gaffer tape" around him.
Recording his verdict, Mr Knapman said Mr Greening died from a "mixed drugs toxicity" or overdose and not from being held "in a form of bondage".
Mr Griffin told the inquest he had become concerned about Mr Greening when he noticed that his face was pale and the area around his mouth was grey.
Mr Griffin had initially been arrested on suspicion of murder but was later released without charge when the circumstances of Mr Greening's death had become clear.
Asked by Dr Knapman to confirm that at all times their activity had been "perfectly consensual" between the two men in the privacy of the flat, Mr Griffin replied: "Indeed."
"Kevin and I had a very happy and very vigorous sex life," he said.
"It was not conventional by heterosexual norms perhaps but it was a sex life which was vigorous and imaginative and we enjoyed each other."
The inquest heard that tests on Mr Greening's blood after his death found traces of cocaine and ecstasy.
After leaving Radio 1, Greening worked for BBC Radio 5 Live and the BBC World Service.
He was also heard on London stations including Jazz FM and Heart 106.2, before taking on the mid-morning show at indie broadcaster XFM.
At the time of his death, Greening was a presenter on London's Smooth Radio.
