President Donald Trump pledged Wednesday to put an “extremely big dent” in the scourge of drug addiction in America as he signed legislation intended to help tackle the opioid crisis, the deadliest epidemic of overdoses in the country’s history. The legislation will add treatment options and get the U.S. Postal Service to screen overseas packages for a synthetic form of opioids called fentanyl that are being shipped largely from China. The measure mandates advance electronic data on all international packages, including those delivered by the Postal Service, and set deadlines for the screening to be put into place by the Department of Homeland Security, Customs, and Border Protection and the Postal Service.
