Dania Beach, Fla. (AP) Florida authorities are calling Anna Nicole Smith's death an accidental overdose.
Broward County Medical Examiner Joshua Perper says a combination pf medications led to ``combined drug intoxication.'' they included sleeping medication and a lengthy list of others, including methadone.
Perper says Smith had been on several anti-depressant and anti-anxiety drugs.
The sleeping medication can be used as a sedative for treating insomnia, alcohol withdrawal, anxiety and post-surgery pain.
Smith was found unresponsive in her room at the Seminole Hard Rock hotel and casino in Hollywood last month.
Seminole Police Chief Charlie Tiger says investigators have ``found nothing to indicate any foul play.'' the medical examiner says the detailed autopsy also showed no evidence of disease.
