Instead of letting the Taliban buy the opium for dirt prices from the farmers in Afghanistan which they rely on to live. Buy up the opium and make it into drugs for third world countries. It would help bring down the price of pain killers for everyone. Right now the drug companies have set prices and should be looked into for antitrust.
Paying the farmers two or three times what the Taliban is paying would bring them over to your side. They would live better. The drug prices around the world would go down. Third world countries could get the drugs for free or close to it where they couldn’t afford them before. It would take the drugs out of the hands of the narco traffickers taking the drugs off the streets. Everyone wins.
