Mark Perrault and a registered nurse talk as part of his treatment regimen for opiate dependency in Boston
Mark Perrault (L) and registered nurse Sam Clark talk during Perrault's weekly nurse visit as part of his treatment regimen for opiate dependency at the Suboxone clinic at Boston Healthcare for the Homeless Program in Boston, Massachusetts January 14, 2013. Suboxone is an opiate replacement therapy drug used to help treat opiate cravings and withdrawl. Drug overdoses have overtaken AIDS-related causes to become the leading cause of death of homeless adults, according to a study of homeless residents of Boston who received treatment from the Boston Health Care for the Homeless Program, though its broad conclusions apply to homeless populations in many urban parts of the United States, the study's author and homeless advocates said.
