This webinar covers some of the most recent threats that law enforcement is now encountering in the war on drugs. The content focuses specifically on what's new out there as well as how to detect it.

Our panel of experts discuss the transition from organic cash crops to pharmaceuticals, including both diverted and counterfeit pills. They take a deep dive into fentanyl as one of the most prevalent drugs of abuse today, from defining it, to its sources, how it's consumed, and understanding its impact on users and the illicit drug trade overall. The sedative xylazine is also reviewed, including types and how it's used alongside fentanyl. Nitazenes are also introduced as law enforcement encounters these synthetic opioids on an increasingly frequent basis.

Finally, our panel covers the popular Thermo Scientific TruNarc Handheld Narcotics Analyzer with proven Raman technology for safe, reliable narcotics ID in the field.
