How effective are CIA drones at identifying fentanyl labs in Mexico?

CIA drones have reportedly proven highly effective at identifying fentanyl labs in Mexico due to the specific chemical emissions from these facilities that make them easily detectable from the air. This technological advantage has provided valuable intelligence in the fight against drug cartels and fentanyl production. However, the implementation of this intelligence has faced challenges. During the Biden administration, the Mexican government was reportedly slow to take action against the labs identified by American surveillance, creating obstacles in the collaborative effort to combat drug trafficking despite the drones' effectiveness in locating the production facilities.
