Since June 2019, local law enforcement has had trouble distinguishing between legal cannabis (hemp) and illegal cannabis (marijuana). Previous testing methods were cost prohibitive and not specific enough to determine THC content. The Houston Forensic Science Center has been working with law enforcement to more effectively identify illegal cannabis products. Additionally, the Texas Department of Agriculture has registered more than a dozen labs to test Texas grown hemp and hemp products manufactured within the state. Our panelists will discuss their experience testing cannabis and challenges they've encountered along the way.
