What is the purpose of the US drone program over Mexico initiated under Biden?

The drone program initiated under Biden aims to fly surveillance drones over Mexican territory to locate fentanyl labs. It's a non-lethal intelligence-sharing program where information gathered by US drones is passed to Mexican counterparts to facilitate actions like arrests. Originally under the Justice Department, the program has been ramped up significantly and may now operate under the Pentagon or CIA's realm. Unlike armed drones in places like Pakistan, these are strictly reconnaissance tools designed to gather information in a collaborative effort with Mexico to combat the fentanyl crisis.
