Law enforcement agents are seeing a dizzying array of structurally similar drugs that challenge existing rapid screening and presumptive testing methodologies. Current methods can lack specificity for preliminary identification of illicit drugs, demonstrating the need for time-sensitive, rapid screening methods with increased structure selectivity and high discriminating power to help identify the assortment of designer drugs. Nuclear Magnetic Resonance (NMR) spectroscopy offers a solution to this challenge by providing structure sensitivity and high discriminating power.
