The Residential Drug Abuse Program (RDAP) and the Non-Residential Abuse Program (NRDAP) are offered by the Federal Bureau of Prisons (FBOP) to assist inmates suffering from substance abuse issues.
RDAP consists of 3 intensive phases, totaling over 500-hours of voluntary individual and group treatment, and it is about 9-12 months long. This program offers prisoners to live in a modified prosocial community within the prison, separate from the general population. They split their day in half with vocational, work, or school activities and the other half in treatment/programs. Prisoners must meet specific requirements to be considered for this program, and space is often limited. The prisoner must have at least 24 months remaining in their sentence to complete the program.
Since some inmates may have less than a 24-month sentence, the FBOP also offers a Non-Residential Drug Abuse Program (NRDAP), where prisoners can participate in 12-24 weeks of Cognitive-Behavioral Treatment. This treatment consists of skill-building within communication, rational thinking, and institution adjustment. NRDAP is often offered in a group setting and is more accessible to prisoners because of the less strict qualifications. NRDAP differs from RDAP because offenders may join this program if they have short sentences, are not eligible for RDAP, or awaiting availability.
The key benefit other than treatment is that those inmates who successfully complete either program may be eligible for a maximum pre-release time in a residential re-entry center, such as a halfway house, where treatment continues thus shortening the actual time incarcerated.
