The death of Peaches Geldof was "not entirely" a case of history repeating itself, the coroner has told an inquest.
North West Kent Coroner Roger Hatch said: "By November last year she had ceased to take heroin as a result of the considerable treatment and counselling that she had received.
"This was a significant achievement for her, but for reasons we will never know prior to her death she returned to taking heroin."
Ms Geldof's mother, Paula Yates, died from an accidental heroin overdose in 2000 at the age of 41.
