Rapper Pimp C, from the group UGK, died from an overdose of this combination.Codeine is used in illegal drug laboratories to make morphine. Detection
Codeine and its major metabolites may be quantitated in blood, plasma or urine to monitor therapy, confirm a diagnosis of poisoning or assist in a medico-legal death investigation. Drug abuse screening programs generally test urine, hair, sweat or saliva. Many commercial opiate screening tests directed at morphine cross-react appreciably with codeine and its metabolites, but chromatographic techniques can easily distinguish codeine from other opiates and opioids. It is important to note that codeine usage results in significant amounts of morphine as an excretion product. Furthermore, heroin contains codeine (or acetyl codeine) as an impurity and its use will result in excretion of small amounts of codeine. Poppy seed foods represent yet another source of low levels of codeine in ones biofluids. Blood or plasma codeine concentrations are typically in the 50–300 µg/L range in persons taking the drug therapeutically, 700–7,000 µg/L in chronic users and 1,000–10,000 µg/L in cases of acute fatal over dosage.Codeine is produced in the human body along the same biosynthetic pathway as morphine. Urinary concentrations of endogenous codeine and morphine have been found to significantly increase in individuals taking L-DOPA for the treatment of Parkinsons disease. Legal status
Around the world, codeine is, contingent on its concentration, a Schedule II and III drug under the Single Convention on Narcotic Drugs.

Management
Each of the symptoms of situs ambiguus must be managed with appropriate treatment dependent upon the organ system involved. Intestinal malrotation is treated surgically using the Ladd procedure. This procedure widens a fold in the peritoneum so that the intestines can be placed in non-rotated formation. It is not possible to return the bowel to a normal morphology However, 89% of patients that undergo the Ladd surgery experience a complete resolution of symptoms. Following cholangiogram, a Kasai procedure is usually performed in cases of biliary atresia. In this surgery, a Y-shaped shunt is used to passage bile from the liver directly to the intestine. If this is unsuccessful, liver transplantation can be considered based on the overall health of the patient. The Kasai procedure is successful in approximately 80% of patients. Following the operation, patients are advised to take fat-soluble vitamins, choleretics, and anti-inflammatory medications. Functionally asplenic patients have an elevated lifetime risk of sepsis, as they have no functional spleen for fighting infection. For this reason, asplenic patients are under constant observation for any signs of fever or infection. In the case of infection, patients are placed on controlled empiric antibiotic therapy to avoid development of antibiotic resistance. This therapy battles infection by both gram-positive and gram-negative bacteria.
