Anna Nicole Smith's son Daniel had at least seven drugs in his system when he died on Sept. 10, toxicology reports indicate.
Dr. Cyril Wecht, a private pathologist hired by the Smith family, confirms to PEOPLE that the antidepressant Amitriptyline, as well as two over-the-counter cold medicines, were found in Daniel's body along with methadone and the antidepressants Lexapro and Zoloft. Sources also tell PEOPLE that a mild over-the-counter sedative was found in the 20-year-old's system.
However, Wecht said the other medications played no role in Daniel's death, and reiterated his assertion that Daniel was killed by the combination of Lexapro, Zoloft and methadone. Of the other medications, he said, "The levels are insignificant and they don't mean a thing. They're of no consequence."
