According to Alfred W. McCoy, author of The Politics of Heroin, in 1983 Pakistani President Muhammad Zia ul-Haq allows Pakistani drug traffickers to deposit their drug profits in the BCCI bank without getting punished. The criminal BCCI bank has close ties to the Pakistani government and the US funding of the Afghan war. It will be shut down in 1991. BCCI also plays a critical role in facilitating the movement of Pakistan’s heroin money. By 1989, Pakistan’s heroin trade will be valued at $4 billion a year, more than all of Pakistan’s legal exports. [McCoy, 2003, pp. 480]
