what are 4 bars pills?
Most Xanax bars are indented in one or two places to allow a person to break them apart for smaller doses. Some Xanax bars can be divided into as many as four pieces to provide four doses of 0.5 or 0.25 milligrams. “Planks,” “zanies,” and “school buses” (for yellow pills) are common slang terms for Xanax bars.
