The death of a blind man who fell from his fourth-floor balcony was an accident possibly contributed to by a psychoactive from cannabis, an inquest has found. 

Potters Court resident Mark Williams was 900 times the legal driving limit for the substance - the principal psychoactive constituent of cannabis - when he died. 

The 60-year-old had been suffering from lymphoma and was taking cannabis oil and oral morphine to manage his pain.

Concluding a five-day inquest into his death, Area Coroner Rosamund Rhodes-Kemp said Mr Williams had been misusing his medication and was found with high levels of THC in his blood.

Mrs Rhodes-Kemp said: "We don't know the exact circumstances in which he ended up there. 

"My conclusion is accident possibly contributed to by very high levels of THC."

Mr Williams' mental health issues and visual impairment were also a contributing factor, she said.

Addressing Mr Williams' two daughters, Lucy and Jessy, the coroner said: "Thank you to both of you for being so brave throughout this. 

"I'm very very sorry for your loss. I feel deeply for both of you."

Mrs Rhodes-Kemp said there had been attempts to move Mr Williams to a ground-floor flat after he was diagnosed with cancer due to his "disorientation", but no formal application was ever made. 

His daughters and carers told the inquest they had raised concerns about him living on such a high floor but "things were not getting addressed".

Housing officers at Southampton City Council, which owns the block of flats on Wimpson Lane, defended their decision to house Mr Williams on the top floor, arguing "insufficient information was provided in his application to support a ground floor need".

In a statement, senior housing officer Deborah Road said: "His care level was assessed as Bronze. (This meant he) could be allocated any one-bedroom flat with no specific need for ground floor accommodation as he could use a lift."

Mr Williams was found dead below his balcony on the morning of November 9, 2021 - five months after moving into Potters Court.

Communication between his family and Apex Prime Care wasn't "what it should have been", a manager admitted.

A review has taken place and more training has been given to staff in the wake of his death.
