Poster Information
Abstract: Controlled substances such as marijuana, cocaine, heroin, and methamphetamines are commonly seized by law enforcement officials and routinely analyzed by forensic laboratories. More recently, synthetic drugs such as bath salts, cannabinoids, naturally occurring herbal remedies, and hallucinogenic mushrooms have gained popularity as chemical stimulants and opiate substitutes. This study focused on the comprehensive profiling of complex botanicals obtained from drug seizures.Summary: Proper sample preparation is critical for the analysis of complex samples. GC-HRT provides high quality, accurate mass data for:
-Spectral similarity searches (NIST, Wiley, etc.)
-Formula determination (fragment, molecular, and adduct ions)
