An autopsy of the funk star Rick James found nine drugs in his system, though his death was due to a heart attack, the Los Angeles County coroner's office announced on Thursday. "Toxicology revealed the presence of the following drugs: Alprazolam (Xanax), Diazepam (Valium), Bupropion (Wellbutrin), Citalopram (Celexa), Hydrocodone (Vicodin), Digoxin, Chlorpheniramine, methamphetamine and cocaine," the coroner's statement said. "None of the drugs or drug combinations were found to be at levels that were life threatening in and of themselves." The cause of death was ruled acute cardiac dysfunction due to idiopathic cardiomyopathy, or an enlarged heart. David Campbell, a spokesman for the coroner's office, told The Associated Press, "He didn't die of a drug overdose." Mr. James, who sang "Super Freak" and other hits, died on Aug. 6 at his home in Los Angeles. He was 56. BEN SISARIO
