I'm convinced from my time in SE Asia that the CIA was running heroin out of the Golden Triangle -- one example being an op in Laos to take out a target 15 miles from the CIA outpost there, something they could as easily handled. Again in Central America in the late 70s we were getting top-notch supplies and giving the "insurgents" old M-1 carbines and other leftovers from WWII and Korea. There was talk of drugs being used to purchase weapons then. The scuttlebut among mercs has always been that the CIA has been involved in smuggling drugs. Coca Cola is also involved.
