There were more heroin-related deaths in Maryland and Virginia in 2013 than any year since 2007. The spike is prompting political leaders in both states to consider new steps to combat opiate addiction.

Although most of the deaths in Maryland were concentrated in Baltimore and Baltimore County, the number of jurisdictions with at least 20 heroin-related deaths grew from three in 2011 to seven in 2013.

In Virginia, the number of jurisdictions with at least one heroin-related death grew from 27 in 2011 to 45 in 2013.

Sources: Maryland Department of Health and Mental Hygiene and Virginia Office of the Chief Medical Examiner. Virginia totals do not include heroin-related deaths with unknown counties. 2014 data is year-to-date through June for Maryland and year-to-date through Sept. 12, 2014 for Virginia. Due to lag time in toxicology results, data reported after July 1, 2014 grows increasingly more incomplete.
