The 25-year-old daughter of Bob Geldof and the late Paula Yates was found dead by her musician husband, Thomas Cohen, at their home in Wrotham, Kent, on April 7.
At an inquest in May, Detective Chief Inspector Paul Fotheringham, of Kent Police, said recent heroin use "was likely to have played a role" in her death.
In an interview published this week in The Spectator magazine, Ms Geldof spoke of the pressures of fame and said she felt people thought she would die in the same way as her TV presenter mother, who died from an accidental heroin overdose at her London home aged 41 in 2000.
Just weeks after the interview, the mother-of-two, who had been a high-profile figure on social media, was dead. Her final post on Twitter was a picture of herself and Ms Yates.
She told journalist William Todd Schultz: "I'm young but people all know the same information about me.
"That's the worst thing, the preconceptions.
"Your life, they keep telling you, is pre-ordained - I'm going to die like my mother. 'She's going to end up like her mother.'
"And people expect you to spew these intimacies to them, like you are in a church confessional.
"It's an interview, not a therapy session."
At her funeral service in Davington, near Faversham, Kent, Ms Geldof's body was carried into the church in a coffin decorated with a picture of her family.
