Vaguely remember someone telling me that the CIA funds itself in part by using Afghanistan as a massive opium factory. Can anyone confirm? Haven't been able to find concrete sources that I can show my lib friends.

Not necessarily that the US was directly making money from the opium there, but that the CIA knowingly facilitated its growing and transport so as to help the Mujahideen fund themselves
