Drug Identification Unit of the Police Crime Lab

The Crime Lab Drug Identification Unit analyzes evidence submitted by the Metropolitan Nashville Police Department for the presence or absence of controlled substances.

Types of evidence typically received by the Drug Identification Unit include: powders, tablets/capsules, plant material, and other substances suspected to contain controlled substances.

Several analytical techniques are utilized to confirm controlled substances in evidence submissions such as Gas Chromatography/Mass Spectrometry, Fourier Transform Infrared Spectroscopy and Gas Chromatography/Infrared Spectroscopy. Scientists will often present their findings as an expert witness in a court of law.
