Six years after Whitney Houston's death, her ex-husband has said he does not think drugs played a part in the superstar's accidental drowning.
Singer Bobby Brown told Rolling Stone that she was really working hard on herself to try to be a sober person.
Brown, who was married to Houston from 1992 to 2007, rejected the notion that drugs were a factor in her death.
Asked what he believes led to Houston's death, Brown said: "Just being brokenhearted."
Toxicology testing measured 0.58 micrograms of cocaine per milliliter of blood drawn from a vein in Houston's leg during the autopsy in 2012.
Along with cocaine, toxicology tests found marijuana, the anti-anxiety drug Xanax, the muscle relaxant Flexeril and the allergy medicine Benadryl, with the coroner's report concluding that the prescription drugs did not contribute to the death.
