Methamphetamine remains the major drug threat in Texas, according to Jane Maxwell’s latest statewide report. All indicators of drug use, such as poison control calls and deaths, show that methamphetamine is a larger problem than heroin. Heroin in Texas is either black-tar heroin or powdered brown heroin. To prevent an overdose, fentanyl test strips should be used to determine if the package contains fentanyl. In Texas, of the top 25 items seized and identified in Texas laboratories reporting to the National Forensic Laboratory Information System, heroin ranks No. 4 and fentanyl ranks No. 21.
