Slang for Xanax but is actually mispelled "Barz" !!! If you don't understand ...research it. Barre- brand of codiene and promethizine cough syrup made by Barre Pharmaceuticals also slang for Xanax but spelled incorrectly(Barz). For all you Syrup sippers out there a word of advice: Do not add candy: Jolly ranchers ect... Sugar kills the codiene.
