I think the most effective countermeasure is just good tracking ability. Drones are pretty conspicuous -- having one land in your backyard is like a giant billboard saying "DRUG DEAL IN PROGRESS, RIGHT HERE!"

The counter-countermeasure, of course, is to start making "deliveries" to random people, and tie up law enforcement by compelling them to arrest innocent parties.

Wonder how many small-time dealers are already selling smaller quantities via FPV with a drone. Take the drugs off, attach the cash, fly back to the car a mile away...anonymous, no risk of confrontation, you know where you're delivering to if they fail to pay etc.
