'Jersey Shore' The Unit -- Charged with Drug Possession, Hedges on Guilt

The Unit from "Jersey Shore" is gearing up to face the music on a drug possession charge in New Jersey -- and he ain't exactly denying the allegations.

The newest MTV reality star was arrested last summer at the "Jersey Shore" party house in Seaside Heights -- when cops claim they found the drug "Special K" on his person. Special K is a hallucinogen, similar to PCP.

Unit called in to TMZ Live moments ago ... and though he admitted to having drug problems in the past ... he wouldn't talk about the specifics regarding the current charge.

When asked if he'd be open to a plea bargain to avoid jail time ... Unit hedged his answer.
