The boyfriend of Whitney Houston's daughter, Bobbi Kirstina, died of a heroin overdose.
According to the autopsy and toxicology report, Gordon died of a heroin overdose after he was found in cardiac arrest inside of a Florida hotel room.
Gordon had traces of Narcan in his system when he died, according to a report, which makes sense considering they would use the drug to counteract the effects of opiates.
The 30-year-old was hospitalized for 7 hours before he died.
At the time of his death, Nick's attorney said, "My heart is heavy today after learning that my long time client Nick Gordon died at the young age of thirty. While I cannot speak to the specific circumstances of his death, I can say that it's been truly heartbreaking to have witnessed first hand the total devastation that drug addiction has wreaked upon a group of young friends, all of whom were loved and had immense potential."
