The King of Pop died as a result of "acute propofol intoxication", a release from the coroner's department revealed on Friday.
Earlier this week, court documents disclosed that Jackson's personal doctor, Dr Conrad Murray, administered propofol - a powerful sedative - just hours before the singer collapsed at his rented Los Angeles home.
According to the coroner's report, the effect of the psychoactive drug benzodiazepine contributed to Jackson's death.
Alongside propofol and the benzodiazepine lorazepam, investigators found a cocktail of other drugs including diazepam and ephedrine in the singer's system.
The cause of the 50-year-old's death and ruling of homicide are in line with leaks made to the press earlier this week.
Under US law, homicide could refer to murder or negligent or reckless manslaughter.
Jackson's doctor has not been named as an official suspect, but court records have identified the 51-year-old physician as the subject of a manslaughter investigation.
