Portland saw a 25 percent increase in overdoses in 2019 compared to the year before — and seven fatal and 79 non-fatal overdoses in illegal drugs since May 1, according to police. “There have historically been upticks in overdoses here in the city at this time of the year,” police chief Frank Clark said Monday, “but the recent spike and this number of overdoses and deaths over a 70 day period is disturbing and warrants public awareness and notification.” Fatal drug overdoses climbed 7 percent in 2019 in Maine, but remain below their peak in 2017, with 380 Mainers dying from drug overdoses, up from 354 in 2018.
