The Centers for Disease Control and Prevention said Wednesday that four times more men died of a heroin overdose in 2013 than women. Colorado follows that trend -- and a few others -- very closely.

Nationally, the rate of prescription overdose deaths has slowed to an increase of 2 percent each year between 2006 and 2013. In Colorado, the rate of prescription overdose deaths also slowed during the same period. 

But unlike the rest of the nation, Colorado saw more prescription drug overdose deaths from 2010 to 2013, not less. This seems to contradict research that says states with medical marijuana laws have lower rates of prescription drug overdose.

Many Coloradans are working to address the abuse of both prescription drugs and heroin.

A House committee unanimously approved a bill Tuesday to further expand access to naloxone, a drug to reverse heroin or prescription drug overdoses.

And earlier this month, Gov. John Hickenlooper was on hand to launch a public awareness campaign encouraging Coloradans to safely dispose of their prescription medications.
