| After receiving reports of several deaths relating to impure anesthetics, the Office launched an investigation into the cause. There were several anesthetics on the market at the time, but this investigation focused on ether and ethylene. This was broadened over the years and continued into the mid-1930s. By the conclusion of the investigation, the Office determined that the decomposition of anesthetics was a result of poor manufacturing practices. As part of this inquiry, the Office established a Laboratory dedicated to drug analysis. |
