research on addiction

Objective: Morphine is one of the important narcotics which constitutes one of the alkaloid and opium components. If this substance is prepared defectively, it will appear in a variety of colors. Therefore, it is not possible to identify this substance by its color. Method: In this study, drug addicts were invited to take urine tests. After morphine extraction from urine samples by chromium toxicity method, different standard concentrations were injected into HPLC device and the resultant diagrams were analyzed. Then, some changes were made into the methodology for the optimality of measurement process and morphine determination in human urine. Results: It was found that the amount of morphine available in the urine samples was measureable through high-performance liquid chromatography and the amount of impurities added to drugs could be determined. Conclusion: This method can be used for diagnosis.
