Can drug courts stop overdose deaths in heroin epidemic?

New Hampshire's court system and emergency services are being overwhelmed by a heroin epidemic - but is locking up addicts the answer?

In the second part of the BBC's series on the epidemic, Franz Strasser visits a so-called drug court where non-violent offenders are put into treatment programmes rather than sent to prison.

These courts exist in just half of the state's counties, however, and the treatment services can only help a fraction of those who are addicted to either heroin or legal painkillers.
