A handheld device is being used by some police departments to determine within seconds whether a seized substance is an illegal drug. It uses Raman spectroscopy, a technology employed now in many drug labs. If results were accepted in court, the TruNarc device could do away with lab testing that now sometimes takes months. The $20,000 instrument "takes the lab right into the street and into the hands of police officers," said Quincy, Mass., Police Chief Paul Keenan.
