Bobbi Kristina Brown's autopsy results have been released, revealing her cause of death.

The Fulton County Medical Examiner disclosed Friday morning that Bobbi Kristina died from hypoxic ischemic encephalopathy and lobar pneumonia caused by water immersion and mixed-drug intoxication when she was found unconscious in her home's bathtub in late January 2015, E! News reported.

The results -- released on what would have been Bobbi Kristina's 23rd birthday -- conclude she took drugs, was immersed in water, developed lung injury, and developed brain injury from lack of oxygen to the brain.

Following the bathtub incident, Bobbi Kristina received treatment at a couple of different prestigious care facilities. She was moved to hospice in June 2015 and died one month later on July 26 surrounded by her family.

"The underlying cause of death is the condition which starts the downhill course of events leading to death and in this case is the immersion associated with drug intoxication," the medical examiner's office said in a statement obtained by People.

"The pneumonia and encephalopathy are more immediate causes which resulted from the immersion and drug intoxication."

According to the toxicology report, marijuana, alcohol, "a cocaine-related substance," sedatives, anti-anxiety medications and morphine were all discovered in Bobbi Kristina's system. The medical examiner's office in Atlanta explained the tests could not determine whether morphine was used to counteract the effects of heroine.

It also remains uncertain whether Bobbi Kristina's death was accidental or intentional, meaning suicide or homicide. However, People previously reported "no significant injuries" were visible at the time of her "non-natural death."

Bobbi Kristina's father Bobby Brown believes his daughter's boyfriend at the time of her passing, 20-year-old Nick Gordon, abused her and therefore played a role in her death.

The Brown family slapped Gordon with a $10 million civil wrongful death lawsuit filed by Bobbi Kristina's conservator Bedelia Hargrove late last year.

The lawsuit listed disturbing details of the events that allegedly transpired leading up to Bobbi Kristina's body being found face down and unresponsive in her Roswell home's bathtub -- including how she and Gordon allegedly got into a terrible argument during which he gave her a "toxic cocktail" that left Bobbi Kristina unconscious with a tooth hanging in her mouth.

"The recent lawsuit against Nick is slanderous and meritless," Gordon's legal team said in a statement as a response to the lawsuit.

"Nick has been heartbroken and destroyed over the loss of his love, and it's shameful that such baseless allegations have been presented publicly. Nick has engaged civil counsel and intends to defend the lawsuit vigorously and expose it for what it is: a fictitious assault against the person who loved Krissy most."

Bobby released a statement regarding the release of Bobbi Kristina's autopsy report.

"First and foremost, 23 years ago today, Bobbi Kristina was born. Krissy will always live in my heart and soul. I love my baby girl," Brown said, according to E! News. "For news affiliates to seek and obtain my daughter's autopsy report, before anyone has been brought to justice for her death is mind blowing to me. Please pray for my family."

Brown's attorney, Christopher Brown of Brown & Rosen LLC, also suggested justice has yet to be served.

"Access to the autopsy of Bobbi Kristina Brown... is unsettling, [but] we will continue in our efforts in the civil lawsuit and the criminal investigation," Christopher said in a statement also obtained by the website.

"Bobby Brown has had to be strong and mourn his loved ones in a fashion that is foreign to most people. So public, so raw, with apparently no end in sight. Hopefully public indictments and prosecution will lead to private healing and closure for Bobby Brown and his family."
