On January 17, 2017, the Washington/Baltimore High Intensity Drug Trafficking Area (HIDTA), with support from the Office of National Drug Control Policy, will launch its real-time overdose mapping smartphone application known as ODMap. ODMap will enable police, fire and emergency medical service personnel to report known or suspected overdose events, and there is no cost to use the application. ODMap sends geocoded event information to a secure server, where it is mapped and made available for view by all participating agencies. Within 15 seconds after an overdose event is reported on the application, the event is mapped. Users are able to sort events by date, time and location to identify overdose spikes. Through ODMap, public health and public safety agencies have teamed up to stem the increasing number of drug overdoses. For more information, public health and public safety agencies should contact Washington/Baltimore HIDTA Deputy Director Jeff Beeson at firstname.lastname@example.org or call (301) 489-1700 to schedule a demonstration.
