The L.A. County Coroner’s office has released the findings of their autopsy on Whitney Houston and have determined that her February 12 death was caused by accidental drowning, heart disease and the effects of cocaine use.

Billboard reports the coroner’s report states Houston was found submerged in a bathtub filled with water and lists "cocaine intake" as a cause of the injury.

According to spokesman Craig Harvey, Houston, 48, had cocaine in her system and that it contributed directly to her death. Marijuana, Xanax and Flexeril, a muscle relaxant, were also found but did not contribute to her death. He says the results indicated Houston was a chronic cocaine user.

Beverly Hills police said in a statement there was no evidence of wrongdoing in connection with Houston's death. Officials had previously confirmed that prescription pills were found in the room, but no mention of cocaine.

"We are saddened to learn of the toxicology results, although we are glad to now have closure," said Patricia Houston, the singer's sister-in-law and manager.

Houston was known to have struggled with drug issues for years, but her family had said recently that they believed Whitney had made significant progress in that area.
