MAHWAH - The alcoholic energy beverage 4 Loko is a drink with quite the reputation; the drink is so potent that it's sometimes referred to as liquid cocaine.

Police in North Jersey say that the beverage is causing problems on Ramapo College's campus and they're worried high school students may be doing the same thing.

Mahwah police who responded to Ramapo College campus' 4 Loko calls say that those who had been overindulging would fall unconscious. They say there are at least six instances where students needed to be hospitalized.

Brad Kim, of G and G Liquors in Teaneck, says that the alcoholic drink is flying off the shelves of his store.
