Kansas City police say the use of PCP is increasing, particularly in the city's urban core.
Officers are concerned because they say PCP users often are violent and unpredictable. The drug induces hallucinations and makes many users combative and unable to feel pain.
Police Capt. Todd Paulson calls PCP the scariest drug on the streets. He was one of six officers who were needed to subdue a PCP user in January.
The Kansas City Star reports officers used to see a brief increase in PCP arrests after a shipment came in but would then go weeks without any arrests.
Police are now averaging two to three PCP arrests a week, most involving small amounts for personal use.
