A BODYBUILDER took an overdose because he wrongly believed he had cancer, an inquest heard.
Huddersfield Coroner's Court head how Russell Warburton, 47, discovered a lump on his leg where he had been injecting steroids for many years in 1999.
Despite tests clearing him of the deadly disease he refused to believe experts.
His wife was also seriously ill in hospital at the time.
She died in 2000.
The former miner, who suffered with psychiatric problems, washed 40 tablets down with a bottle of whisky but was saved by doctors.
However, after his failed suicide attempt Mr Warburton, from Barnsley, became mute. His mental and physical health also declined.
During the following four years Mr Warburton's behaviour became erratic.
At various times he pushed a pepper pot down his throat, walked around in urine-soaked clothes and made explicit and upsetting suggestions to carers and nurses.
In 2004 he was transferred to specialist care home Thomas Owen House on Lees House Road in Thornhill Lees.
In August 2004 he was taken to Dewsbury District Hospital suffering from shortness of breath after a chest infection.
His condition declined and he died on October 5, 2004.
Doctors could find no clear cause of death and carried out a post-mortem. They found he had died from hypoxia, or lack of oxygen to his brain, due to the toxic effects of his earlier overdose.
Deputy assistant coroner James Turnbull said Mr Warburton had been "hooked" on steroids and amphetamines, taking "massive doses" of both.
He also paid tribute to nursing and care staff for their "superhuman" efforts.
Mr Turnbull recorded a verdict of suicide.
