Brown-brown

Brown-brown is a form of powdered cocaine, cut with gunpowder. Commonly given to child soldiers in West African armed conflicts, the drug gained notoriety after it was used by Nicholas Cage's character, Yuri Orlov, in the 2005 movie Lord of War. Consumed by insufflation, the gunpowder in the drug irritates the bowels which increases aggression.

It also appeared in the 2006 movie Blood Diamond, the memoir A Long Way Gone by Ishmael Beah and the video game Metal Gear Solid 2: Sons of Liberty.
