Introduction to Chemical Analysis of Illicit Drugs
Forensic chemical analysis of illicit drugs aims to determine if a substance confiscated by legal forces contains an illegal compound, and if so, its purity and preferably origin. Confirmatory tests that unambiguously identify the potential drug and related impurities provide the necessary evidence for law enforcement and for the courts to pursue criminal charges and to determine to sentence. Many drugs contain specific impurities from the manufacturing process or compounds that are intentionally added in order to enhance or modify the drug effect. Their identification is a clue that helps law enforcement to identify sources of raw ingredients and track the distributors.
