For this reason it is essential to include levamisole in postmortem panels. Ideally this analyte would be added to the cocaine confirmation assay. It is currently
This study evaluated the stability of cocaine, benzoylecgonine, and site- specific differences for any of the analytes, and the central compartment showed both
To evaluate the importance of these factors, we used cocaine and cyclosporin A ( CsA) as analytes because they show proton- ated and Ag-cationized species,
