We were going to do this and then stiffed the farmers. We told them if they planted wheat instead of poppies, we'd buy it and give them the difference. Then we cut that part out of the budget. In the end, there were a whole bunch of new wheat farmers pissed at Americans for not making good on their promise. So now poppie production is about 60% of the country. Cool little 2nd and 3rd order effect there.
