According to CNN, UGK’s Pimp C died of an accidental overdose of codeine and promethazine. These ingredients are what makes “syrup” immortalized in Houston’s rap culture and are commonly found in cough syrup.

UGK had a 2000 hit single titled, ironically, “Sippin’ On Some Syrup.”

The county coroner’s office ruled Monday the cause of death was due to large amounts of prescription-strength cough syrup combined with a condition C had known as sleep apnea, which causes people to stop breathing for up to 30 seconds at a time as they sleep.

As previously reported, Pimp C, born Chad Butler, was found decomposing in an upscale hotel room bed on December 4.

C joins the ranks of other southern rap artists, such as the legendary DJ Screw, who died from overdosing on codeine-laced cough syrup.
