The North Louisiana Crime Lab continues to monitor the emergence of cychlorphine, a powerful synthetic opioid that has now been detected in multiple North Louisiana parishes.
Since our first detection in March 2026 in a case from Caddo Parish, additional cychlorphine-positive submissions have been identified from DeSoto, Ouachita, and Natchitoches Parishes.
Laboratory analysis has confirmed cychlorphine in several counterfeit tablet types, including:
💊 Blue "M30" tablets
💊 Green "M15" tablets
💊 Pink "K56" tablets
💊 Yellow "T259" tablets
💊 White "M367" tablets
These tablets are made to resemble legitimate prescription medications, but appearances can be dangerously misleading.
⚠️ The reality is simple: there is no way to know what is contained in an illicit pill purchased on the street. Counterfeit tablets may contain potent synthetic opioids, including cychlorphine, that can significantly increase the risk of overdose and death.
🔹 ONE PILL CAN KILL.
The NLCL will continue monitoring drug trends throughout our region and sharing information that helps protect our communities.
