Forensic drug analysis is the process of identifying unknown powders, liquids and pills that may be illicit drugs or controlled substances.

There are basically two categories of forensic tests used to analyze suspected controlled substances. Presumptive tests, such as color tests, give only an indication of which type of substance is present. Presumptive testing is not sufficient in and of itself to identify the substance. Confirmatory tests, such as gas chromatography-mass spectrometry (GC-MS) or infrared spectroscopy (FTIR), are more specific and can be utilized to determine the precise identity of the substance.

Guidelines for proper forensic analysis of controlled substances are recommended by the Scientific Working Group for Drug Analysis (SWGDRUG). Not all government or private forensic laboratories follow SWGDRUG guidelines.

Forensic Science Consultants is licensed to handle DEA controlled substances (Schedules 1, 2N, 3, 3N, 4, 5). Qualitative drug analysis at FSC is performed following SWGDRUG guidelines with confirmatory testing via Gas Chromatography-Mass Spectrometry (GC-MS) and/or Fourier Transform Infrared Spectroscopy (FTIR). We also perform re-weighing of controlled substances on properly calibrated and certified analytical balances. We are also equipped to perform quantitative analysis of most controlled substances.
