Evidentiary Value of Drug Identification

The identification of marijuana or its chemical constituents has long been one of the most often performed analyses in the forensic drug laboratory. This includes analysis of the very common botanical samples, ranging from whole plants to finely chopped vegetation.”  The court in United States v. Gaskin, 364 F.3d 438, 460 (2d Cir. N.Y. 2004), held that neither actual drug exhibits nor reports of chemical analysis are required to support a conviction for possession of a controlled substance.  Lay testimony and circumstantial evidence may be sufficient, without the introduction of an expert chemical analysis, to establish the identity of the substance involved in an alleged narcotics transaction.
