The Oklahoma State Bureau of Investigation Northeast Regional Laboratory (Tahlequah) recently received a partial sheet of blotter paper, with a Xanax tablet shape with the word “XANAX” inside the tablet shape imprinted repeatedly on one side (see Photo 1) and the word “XANAX” imprinted repeatedly on it in bold letters on the opposite side (photo not shown), suspected LSD. The exhibit was seized in Bartlesville by the Washington County Sheriff’s Office, pursuant to a traffic stop for suspected DUI (Bartlesville is in the northeast corner of the state, near Tulsa). The sheet contained 86 dosage units, segmented into ¼ inch squares. UV irradiation did not give the bright fluorescence usually observed with LSD blotter paper, and analysis of methanolic extracts by GC and GC/MS indicated not LSD but rather alprazolam (not quantitated, but a moderate to high loading based on the chromatograms). A similar submission was previously submitted to the laboratory; however, that exhibit consisted of only two squares, and was imprinted with “XANAX” on only one side. In the latter case, analysis again indicated a heavy loading of alprazolam.
