Controlled Substances

Barcode4Examiners in the Controlled Substances Section analyze materials for the presence of controlled substances and marijuana. Controlled substances may be present in substrates that include powders, solid materials, liquids, plant material, mushrooms, blotter paper, and food items. In addition, the section examines pharmaceutical preparations in the form of tablets, capsules, injectables and transdermal patches. Controlled Substances examiners will also analyze evidence that is related to the suspected clandestine manufacture of controlled substances.

Controlled substances are routinely screened using color tests and thin layer chromatography (TLC) with structural confirmation accomplished through gas chromatography/mass spectrometry (GC/MS).  Additional instrumental techniques such as Accurate Mass Time of Flight Mass Spectrometry coupled with a Direct Analysis in Real Time ion source (AccuTOF-DART), Fourier Transform Infrared Spectroscopy (FTIR) coupled with Attenuated Total Reflectance (ATR), solid state FTIR coupled with Gas Chromatography (DiscovIR), and Gas Chromatography with flame ionization detector (GC/FID) may also be utilized during the course of a controlled substance analysis.

Opioid Handling Resources

Due to the recent submissions of fentanyl, carfentanil, and other powerful synthetic opioids to the Department, special precautions should be taken to minimize exposure when handling, sampling, and field testing powders.  The Department does not recommend field testing hazardous opioids, for more information visit: https://www.dea.gov/divisions/hq/2016/hq061016.shtml
