Heroin treatment

HAVERHILL, MA - JUNE 4: Stephen Barber sleeps during the middle of the day while at Serenity at Summit rehab center in Haverhill, Mass., Saturday, June 4, 2016. The throws of detox were severe for Barber, who had built a high tolerance of heroin and felt he wasn't being given enough suboxone to help him combat the withdrawals. Barber ended up checking himself out of rehab two days later, saying he couldn't handle being woken up every hour to have his vital signs checked. After a week or so back home, he started using heroin again. (Photo by Gabe Souza/Portland Portland Press Herald via Getty Images)
