Peaches Geldof described heroin as "such a bleak drug" in what is thought to have been her last ever interview before she died a possibly drug-related death in April.
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 where she posted a picture of herself and Ms Yates a day before her death, was dead.
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 poignantly decorated with a picture of her young family.
Speaking about becoming a mother to her two sons, Astala and Phaedra - who were 23 months and 11 months old at the time of her death - Ms Geldof said they had changed her life and how people saw her.
"Suddenly I was this earth mother," she said. "It was an overnight transformation. It was so profoundly hateful. Then, out of nowhere, it was 'Dang. We can't hate you anymore. Here she is in her golden hair, etc.' Now, for the first time ever, there was gushing adulation."
Ms Geldof said she was a fan of songwriter Elliott Smith, who had been a drug addict in the later years of his life, and told how she had been thinking about "the sad death of virtuosos", according to the interview.
"Heroin is such a bleak drug," she said. "It always makes me so sad to hear about people like (film director Philip Seymour) Hoffman, who were real masters and also family men who were just wasted by the constant, gnawing obsession with it. All heroin users seem to have the same core internal pain, though. It's a fascinating concept - drug of choice."
Ms Geldof, whose Twitter account has more than 216,000 followers, said of fame: "Anyone who says they don't read their own press is categorically lying. You need to keep on top of it for your work. You cannot be in the public eye and not have it affect you."
Her father, former singer with the Boomtown Rats, paid tribute to his daughter shortly after her death.
In a statement on behalf of himself, his partner, Jeanne Marine, and Ms Geldof's sisters, Fifi Trixibelle, Pixie and Tiger, he said she was the ''wildest, funniest, cleverest, wittiest and the most bonkers of all of us''.
A full inquest into Ms Geldof's death is expected to take place on July 23.
