Ketracel white

In the fictional Star Trek universe, Ketracel white is a white, liquid drug to which genetically engineered Jem'Hadar super-soldiers are born addicted. The drug is supplied to the Jem'Hadar by the Vorta, the middle-men of the villainous Dominion. All Jem'Hadar soldiers are supplied with a device that pumps the drug through a transparent tube into their system from a small capsule. Without the drug, Jem'Hadar soldiers experience painful withdrawal symptoms and eventually death. The drug serves the Jem'Hadar as a form of nutrition, and their genetic structure is designed to be dependent on its presence, in order to prevent rebellion against the Dominion. Only one case of a non-addicted Jem'Hadar soldier is known: an anamoly which was the result of a random genetic mutation.
