RDAP is the Bureau’s most intensive treatment program. CBT is used in a modified therapeutic community model where offenders experience living in a pro-social community. Offenders live in a unit separate from general population; they participate in half-day programming and half-day work, school, or vocational activities. RDAP is typically nine months in duration.

The Bureau and National Institute on Drug Abuse combined funding and expertise to conduct a rigorous analysis of the Bureau’s RDAP. Research findings demonstrated that RDAP participants are significantly less likely to recidivate and less likely to relapse to drug use than non-participants. The studies also suggest that the Bureau’s RDAPs make a significant difference in the lives of offenders following their release from custody and return to the community.
