On 15th April, the Task & Purpose website reported on a leaked memo from February and from the Department of Homeland Security, saying that it is considering designating the painkiller drug fentanyl as a weapon of mass destruction “when certain criteria are met”. The memo offered background on the drug and how some elements of the US government see fentanyl as a potential “mass casualty weapon”. Roughly 50 to 100 times more powerful than morphine, fentanyl is a synthetic opioid that is medically-prescribed to treat severe pain. Illegal versions — usually from China or Mexico — is sometimes manufactured and sold as powder, put in small candies and eye droppers, or mixed into other illicit drugs to increase their potency, which has led to a significant increase in overdoses for unknowing drug users. In 2017, President Trump declared the opioid crisis a public health emergency as tens of thousands of American deaths were traced to fentanyl overdoses in recent years.
