Contaminants in illicit amphetamine preparations

J N Lomonte, W T Lowry, I C Stone

    Journal of Forensic Sciences
    |July 1, 1976
    PubMed
    Summary

    Illicit amphetamine and methamphetamine samples were analyzed using GC/MS and EDX. The presence of zinc and unique by-products indicates their illegal origin, aiding in forensic analysis.

    Area of Science:

    • Forensic Chemistry
    • Analytical Chemistry
    • Organic Chemistry

    Background:

    • Illicit drug manufacturing poses significant public health and safety risks.
    • Accurate identification of controlled substances and their origins is crucial for law enforcement and legal proceedings.
    • Understanding the chemical signatures of illicit drugs aids in tracing manufacturing processes and sources.

    Purpose of the Study:

    • To identify contaminants, excipients, and by-products in illicit amphetamine and methamphetamine samples.
    • To determine the presence of specific elements, such as zinc, used during the synthesis of these illicit drugs.
    • To establish analytical methods for distinguishing illicitly manufactured amphetamine-type drugs from legitimate ones.

    Main Methods:

    • Combined Gas Chromatography-Mass Spectrometry (GC/MS) for compound identification.
    • Energy-Dispersive X-ray (EDX) analysis for elemental composition.
    • Analysis of polycondensation products and manufacturing by-products.

    Main Results:

    • Detected various contaminants, excipients, and by-products in illicit amphetamine and methamphetamine preparations.
    • Identified the presence of zinc in the samples, likely used as a reducing agent during synthesis.
    • Observed characteristic polycondensation products specific to the illicit manufacturing process.

    Conclusions:

    • The detection of specific contaminants, by-products, and elemental signatures (like zinc) can reliably indicate the illicit origin of amphetamine-type drugs.
    • A multidisciplinary analytical approach combining GC/MS and EDX provides valuable data for comparative forensic examinations.
    • These findings support the use of advanced analytical techniques in legal investigations involving seized illicit substances.
