Identification of suspect substances depends on reference materials that are in short supply.   Attempts to understand and control new synthetic recreational drugs are being hindered by analysis laboratories' inability to obtain pure samples of the compounds, experts say. The growing problem of synthetic drugs — which include mimics of cannabis and amphetamine — came [Read More...]
