The 33-year-old Pimp C, whose real name was Chad Butler, was found lying on his bed at the Mondrian Hotel in West Hollywood on Dec. 4 after he failed to check out as expected. The coroner's report said the death was "due to promethazine/codeine effects and other unestablished factors."
Ed Winter, assistant chief of the coroner's office, said the levels of the medication were elevated, but not enough to be deemed an overdose
Butler was a member of the Texas hip-hop duo UGK, which scored a No. 1 album last year with its seventh release, "Underground Kingz."
Rap artist Pimp C, an influential hip-hop figure who had recorded an ode to getting high from cough medicine, died accidentally at a Sunset Strip hotel because of the combination of a medical condition and cough syrup, the Los Angeles County coroner said Monday.
