Law enforcement in Lao Cai province is utilizing widespread drug testing, including urine, saliva, and hair follicle analysis, to identify criminal activity and dismantle local trafficking networks.

In mid-September, police in Mo Vang commune used rapid testing to uncover a group of three individuals organizing illegal drug use, leading to the prosecution of several suspects and a supplier. Shortly thereafter, investigations following drug tests conducted on September 3 resulted in the arrest of a woman for allegedly providing synthetic drugs to a pregnant individual. The case has been transferred to the Lao Cai Provincial Police Investigation Agency.
