The governor’s current point man on the opioid crisis, Clay Stamp, acknowledges that the state’s initial strategy faltered as a surge in the use of deadly fentanyl — which was not a major concern four years ago — more than stripped away some progress achieved in reducing fatalities from prescription opioids and heroin. Fentanyl-related overdoses “continue to increase at an alarming pace,” the state said Friday, accounting for more than three quarters of Maryland’s 1,185 opioid deaths in the first six months of 2018.
