VERY LARGE SEIZURE OF PHARMACEUTICAL GRADE &#8232;KETAMINE HYDROCHLORIDE IN AURORA, COLORADO The DEA Western Laboratory (San Francisco, California) recently received a submission containing three purported pharmaceutical-grade ketamine hydrochloride exhibits, totaling over four kilograms of very fine, fluffy, white powders. The exhibits were seized at a small pharmaceutical firm in Aurora, Colorado by personnel from Immigration and Customs Enforcement and the Food and Drug Administration, and consisted of 30 100-gram bottles, 56 25-gram bottles, and approximately 100 grams of loose powder. The bottles were all factory-sealed and labelled as containing ketamine hydrochloride (e.g., see Photo 6). The loose powder had been taken on-site from two 25 kilogram drums, both also factory-sealed and labelled as containing ketamine hydrochloride. Analysis of the powders by GC/MS, FTIR, and NMR confirmed ketamine hydrochloride in each of the exhibits, all 95 percent or better pure. The drum labels indicated that the material was produced in China. This is one of the largest submissions of ketamine to the DEA Western Laboratory in recent memory.
