Massachusetts spent almost 1 percent of total state government expenditures on costs associated with the opioid crisis in fiscal year 2015.

That’s according to a new analysis by the Federal Reserve Bank of Boston that looked at costs associated with the opioid crisis in New England. At 1 percent, Massachusetts ranks in the middle of New England states when it comes to opioid expenditures.

The Bay State spent more than Vermont and about the same as Connecticut, but less than Rhode Island and Maine, which spent 1.14 percent of total expenditures on costs associated with the crisis. The U.S. government spent .74 percent of its total expenditures on the opioid crisis, putting it below every New England state.

The Fed broke out the costs each state spent into several categories: criminal justice, medical treatment and medical complications. Massachusetts led all New England states in per capita spending at $96.19; the highest category of spending was for medical treatment at about $340 million.

According to the Fed, the opioid epidemic’s impact on state revenues is significant and could affect regional fiscal health. For example, individuals incarcerated for drug crimes or in residential treatment programs are not earning wages. Evidence also suggests that non-institutionalized individuals abusing opioids are more likely out of work than employed, likewise resulting in lost revenue.

The opioid crisis has hit the commonwealth hard in recent years, putting a significant burden on local police and fire departments, as well as other municipal departments. But the state announced in February that opioid-related deaths had declined in 2017 by 8.3 percent, compared to 2016, the first time in many years that the state saw a year-over-year decrease.

The total number of estimated and confirmed opioid-related overdose deaths in 2017 was 1,977, 178 fewer deaths than in 2016.
