The Bexar Forensic Science Center in San Antonio is accountable for identifying a variety of narcotics, such as heroin, cocaine, marijuana, and fentanyl, for criminal investigations. The scientists at the center deal with these substances on a day-to-day basis and function to resolve the mysteries behind them. They analyze all the things from significant seizures to modest amounts of narcotics just before returning them to law enforcement officials. The most normally tested substances are marijuana, meth, and cocaine, with methamphetamine becoming the most regularly identified drug. The scientists have also observed an boost in counterfeit tablets containing fentanyl, especially round blue tablets with the imprint of M30 and tablets that resemble oxycodone. In spite of the unpredictable nature of their function, the scientists are committed to serving and assisting their neighborhood by using the science behind their analyses.
