US Attorney General Eric Holder is calling for federal law enforcement agencies to train and provide their personnel with naloxone, a drug that can help reverse deadly heroin overdoses. Ideally, Holder wants to see the drug made available to anyone who may interact with a victim of a heroin overdose so theyll be ready to use naloxone in situations where its warranted. I am confident that expanding the availability of naloxone has the potential to save the lives, families and futures of countless people across the nation, Holder said in a statement. Federal agencies that fall under his directive include the FBI, Drug Enforcement Administration, and Bureau of Alcohol Tobacco Firearms and Explosives, and US Marshals Service.
