Area of Science:

  • Forensic Toxicology
  • Drug Enforcement
  • Criminal Justice

Background:

  • Cocaine smuggling via internal concealment poses significant challenges for law enforcement.
  • Accurate and efficient detection methods are crucial for identifying smuggled narcotics.

Purpose of the Study:

  • To evaluate the effectiveness of X-ray and immunochemical testing in detecting internally concealed cocaine.
  • To assess the role of urine and saliva analysis as screening tools for drug smuggling.

Main Methods:

  • Investigated 30 individuals arrested for cocaine smuggling.
  • Utilized X-ray examination, immunochemical urine and saliva tests, and chromatographic confirmation.
  • Analyzed characteristics of concealed drug packages.

Main Results:

  • X-ray examination yielded positive results in all 30 cases.
  • Immunochemical urine assays showed limited sensitivity, with positive results only after lowering the cutoff.
  • Saliva tests were negative; drug package analysis revealed consistent manufacturing but interpersonal variability.

Conclusions:

  • X-ray is a highly effective method for detecting internally concealed cocaine.
  • Immunochemical urine screening has a limited role in suspected internal drug smuggling.
  • Drug package characteristics may offer insights into production sites.
