RDAP eligibility: getting in vs. getting the year off
RDAP has two separate eligibility questions families constantly conflate: admission to the program requires a diagnosable substance use disorder documented in the 12 months before arrest (28 C.F.R. § 550.53); the early-release year has its own exclusion list at § 550.55. Plenty of people qualify for the program but not the time off — current firearm-element offenses and prior violent convictions are the classic early-release disqualifiers. Timing is the third gate: the person needs roughly 24 months remaining to complete the 500-hour unit-based phase plus aftercare, so applying early — with the disorder documented in the presentence report — protects both benefits.

What gets someone into the program?
- A verifiable substance use disorder — the drug abuse program coordinator's diagnostic interview, corroborated by documentation from the 12 months before arrest. The presentence report (PSR) is the document BOP trusts most: use described to Probation during the PSR interview usually satisfies this; a silent PSR makes it hard.
- A signed agreement to participate, and enough sentence left to finish — the unit-based phase runs about 9–12 months of half-day programming (500 hours), followed by follow-up treatment and the community phase.
- Volunteering is required — RDAP is opt-in. The waitlist at popular facilities runs months to a year; facility pages on OutDate show which prisons run RDAP and typical waitlist estimates.
Who gets the § 3621(e) year — and who doesn't?
The early-release exclusions at § 550.55(b) are BOP's exercise of discretion the Supreme Court blessed in *Lopez v. Davis*, 531 U.S. 230 (2001). The big categories: a current offense with an element of force or a firearm (including felon-in-possession), offenses that by their nature present a serious risk of physical harm, prior convictions for homicide, forcible rape, robbery, aggravated assault, or sexual abuse of a minor, INS detainees, and pretrial or contractual placements. Completing RDAP while excluded still earns the treatment benefit, FSA credits for participation, and often better halfway-house consideration — just not the year.
What should the family do, and when?
- Before sentencing: make sure substance use is candidly documented in the PSR interview, and ask counsel to request a judicial RDAP recommendation in the Judgment — not binding, but helpful.
- At designation: prefer a facility that runs RDAP with a manageable waitlist when advocating on designation.
- On arrival: have the person request the RDAP interview through Psychology Services early — the waitlist clock and the 24-months-remaining math both reward speed.
- If excluded from early release: verify which conviction triggered it; exclusion determinations contain errors and can be challenged through the administrative remedy process.

Does marijuana or alcohol count for RDAP eligibility?
Yes — any diagnosable substance use disorder qualifies, including alcohol and cannabis, if documented in the year before arrest. What matters is the diagnosis and the paper trail, not the substance.
Can someone do RDAP with a gun charge?
Usually they can take the program; they generally cannot get the early-release year — § 550.55(b) excludes current offenses involving a firearm, and BOP applies that to felon-in-possession. FSA credits for participating are typically still available if the offense isn't FSA-excluded.
What happens if someone is expelled from RDAP?
Expulsion or withdrawal forfeits the provisional § 3621(e) date and can affect halfway-house planning. Readmission is possible at staff discretion, but the sentence-length clock keeps running — another reason to start early.
Is there a non-residential option?
Yes — the Non-Residential Drug Abuse Program (NRDAP) for people who don't meet RDAP criteria or lack time to finish it. It earns FSA credits as assigned programming but carries no § 3621(e) reduction.
