We report the emergence of a new group of substances of abuse in the USA, known as bath salts, with quantitative results in 18 patients. State and federal authorities used timely information from poison centers on the bath salt outbreak during investigations to help track the extent of use and the effects occurring from these new drugs. Close collaboration between state authorities and poison centers enhanced a rapid response, including legislation.

The analysis of mixtures of "crystal meth" (usually comprised of methyl sulfone [MS] and methamphetamine [MA]) by gas chromatography-mass spectrometry (GCMS) is routine in many forensic drug laboratories. The utilization of Raman spectroscopy for the identification of such mixtures quickly and without the need for a separation technique is discussed. Samples were dissolved in water and Raman spectra of the resulting aqueous solutions were collected. By comparing these spectra to spectra of methylsulfone and MA mixtures of known composition, an indication of the composition of the sample can be obtained in only a few minutes. This spectral comparison also can be used as a semi-quantitative analysis of MA concentrations in such exhibits.
