Degradation in soil of precursors and by-products associated with the illicit manufacture of methylamphetamine: Implications for clandestine drug laboratory investigation

These findings have implications for the forensic assessment of buried residues recovered from clandestine laboratory sites because markers used to infer the synthetic methods used might be absent as a result of degradation and because methylamphetamine might be present in residues as a result of degradation rather than as a direct result of its manufacture in the laboratory.
