Screening method for identification of forensic drugs

Introduction

The term “forensic” drug refers mainly to chemical or plant-derived substances that affect psychological, behavioral, or physical functions, and lead to varying degrees of dependence or addiction. Confiscated drugs have to be tested for their identity in a cost-efficient way in police labs worldwide. To check for identity by HPTLC, micro-chemical reactions (derivatizations) can be performed on the plate after development, evaluated within a short time, and at low costs. Further confirmation can be achieved by comparing UV and mass spectra of samples and references.
