What Are the
ROADBLOCKS ?
•
Lack of Methadone Treatment Access
Availability of BUPRENORPHINE may facilitate
more widespread use of pharmacological treatments
•
Changing the Culture
Education of judges
Secondary CJ-DATS goal – to help change
the culture by embedding research into existing settings
•
Infrastructure to Support Transition to the Community
Ancillary services are critical to successful transition
