AUGUSTA, Maine (AP) A report says drug overdose deaths increased slightly in the first three quarters of 2019 in Maine, where the nationwide opioid crisis has taken a heavy toll.

The report by Dr. Marcella Sorg of the University of Maine’s Margaret Chase Smith Policy Center said Thursday that 277 Maine deaths from January to September of 2019 were caused by drugs.

Numbers for all of 2019 haven’t been released yet, but the death total is forecast to be 4 percent higher than 2018, when 354 drug-related deaths were reported.

More than 80% of the overdoses were the result of at least one opioid.

Non-pharmaceutical fentanyl deaths constituted four-fifths of all opioid deaths in 2019.
