Howabout this:

We buy up the Opium from the farmers. Modify it into a morphine like stuff, and sell it cheap to the millions of aids victims in Africa and other third world countries, who are dying and have nothing to help them, because the only treatment that you can get is very expensive.

Stops the drug trade from Afghanistan, supports the Afghan economy, helps suffering people about to die.

I mean, it beats than going in with a bunch of guns, taking away the crops and pumping a few guys full of lead…

What do you think about it?
