“We need to get ahead of this crisis, it is the deadliest drug epidemic in our nation’s history,” Hennepin County Sheriff Rich Stanek said, at a news confernce. “We need to do more to prevent opioid abuse way before it begins.”

The sheriff also said that the number of opioid related deaths last year would likely have been much higher, perhaps 105 deaths higher, if it were not for anti-overdose drugs being available to first-responders.
