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 of 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.
