U.S. Attorney General Eric Holder listens to a question at a hearing of the Senate Judiciary Committee on Capitol Hill in Washington

U.S. Attorney General Eric Holder is calling for more law enforcement agencies to equip their personnel with naloxone. This drug can reverse a heroin overdose and it’s essential for helping people who are in the process of a heroin overdose.

Holder also said that emergency use of naloxone had resulted in more than 10,000 overdose reversals since 2001. However, fatal heroin overdoses have increased 45% from 2006 to 2010. Of those deaths, 3,038 were reported in 2010, showing a huge increase in that year alone.

Unfortunately, many experts believe the rise in heroin use has something to do with the decrease of prescription pain killer use. In Florida, pill mills were wildly popular until a government crackdown put an effective damper on the stream of pills into the black market. A lack of supply combined with high demand let to a skyrocketing price. Many addicts turned to heroin because it’s a cheaper, yet similar high.

Now, a high demand for heroin has led to a ramp up of production in Mexico. Holder cited a 320% increase in the amount of heroin seized on the US-Mexico border between 2008 and 2013.
