NARC

A zero-calorie carbonated beverage. The drink of choice for Drebin and Little Gray. Drebin's armored vehicle carries a vending machine stocked full of it. It is highly carbonated and stimulates the circulation of nanomachines in the bloodstream via alpha-carbonic anhydrase activity within the body.

It's worth mentioning that those who have the Sons of the Patriots nanomachines implanted in their body are unaffected by alcohol because the nanomachines break it down.
