Whitney Houston drowned to death, but she also had drugs in her system, the L.A. County coroner's office said on Thursday, giving its first official ruling on the singer's cause of death.

The singer also suffered from heart disease and had cocaine in her system, which were "contributing factors," according to ABC, but the official cause of death was drowning. CNN reported that while the final toxicology reports wouldn't be out for another two weeks, it appeared Houston had a heart attack, which made her go under the water. As we pointed out after her death, full toxicology reports can take months, but an L.A. County Coroner's lieutenant told us at the time that the office would expedite the case. The initial coroner's report, filed on Feb. 15, officially listed her cause of death as "deferred."
