When he's not busy getting wasted in The Hangover 2, Bradley Cooper is... selling drugs? A new viral ad campaign for Limitless is underway, featuring Cooper in a infomercial-like video for a new wonder drug called NZT. Limitless is based on the novel The Dark Fields, which follows writer Eddie Morra as he stumbles upon a mysterious new drug that allows you to "access 100% of your brain" but has some pretty horrific side effects.

Take a look at the viral video below and discover more about NZT over at TheClearPill.com! Limitless arrives in theaters on March 18th, 2011.
