Why not replace opium farming with marijuana farming, supplying legitimate medical marijuana needs and legal markets in US and Europe with fair prices? The CIA could still do their drug running, but with less inhumane effects on the local/world populace.

During G. W. Bush’s last term in the White House, a coalition group of Afghan farmers presented a proposal to the American military commander to sell their opium crop to American drug companies instead selling their crop to the Taliban. The Commander sent the proposal directly back to President Bush, who sat on it for a week. Then he called in some drug company executives for a meeting in the Oval office, and passed the Afghan farmer’s proposal by the drug execs. The drug execs discussed it for a while and then turned thumbs down on the idea.
When the word finally reached the Afghan farmers, they were crushed as the refusal meant that they had nowhere to go except back to the Taliban to sell their crop. For the farmers this rejection meant a continued loss of financial freedom in addition to the continuation of brutal abuse by the Taliban. This happened just before the farmers brought in the largest crop of opium in years. Bush blew a perfect chance to release the strangle hold that the Taliban have had over the Afghan farmers. But this is typical of the eight years under the Bush presidency.
