Police found 79 syringes hidden inside a black cloth bag with "importation quality" heroin at Peaches Geldof's home, an inquest has heard.
Detective Chief Inspector Paul Fotheringham, who led the investigation into Ms Geldof's death, said: "The black bag also contained 34 medical syringes, some were with needles and some without, some were sealed in original packaging and some contained traces of a brown coloured residue.
"There were also 45 packaged and sealed syringes, alcohol wipes and cotton buds."
Police also found a pair of knotted black tights under Ms Geldof's body and two other pairs of tights with knots in them elsewhere in the property, likely to have been used while she took the drug.
