Most drug offenses qualify — start there
It is worth stating plainly, because fear and folklore run the other way: the majority of federal drug convictions are eligible to earn First Step Act time credits. The exclusion list in 18 U.S.C. §3632(d)(4)(D) reaches specific high-level drug offenses, not drug offenses as a class. A standard possession-with-intent or distribution conviction under 21 U.S.C. §841 is, in most subsections, fully credit-earning.
This matters because families are routinely told otherwise — sometimes by other people inside, sometimes informally by staff. The correct posture is to assume eligibility and then verify against the judgment, rather than to assume exclusion and give up a year of credits without checking. Our eligibility guide covers the general framework; this page focuses on the drug-specific lines.
The high-level exclusions that do apply
The clearest drug exclusion is a conviction under 21 U.S.C. §848 — continuing criminal enterprise (CCE), the federal "kingpin" statute. Also excluded are certain high-level §841(b)(1)(A) and §960 convictions where the offense involved a large quantity and the person was an organizer, leader, manager, or supervisor as determined at sentencing, and certain offenses involving death or serious bodily injury. The enumerated list controls, and it is specific.
The distinction the BOP must make is between a high-level trafficking conviction that meets the enumerated criteria and an ordinary trafficking conviction that does not. Two people convicted under the same broad statute can land on opposite sides of the line depending on subsection, quantity findings, and role. This is exactly the kind of fine distinction where coding errors happen.
The §841(b)(1)(C) point families should know
A conviction under 21 U.S.C. §841(b)(1)(C) is a frequent flashpoint. That subsection carries no mandatory minimum, is not a high-level quantity offense, and is not on the exclusion list. Yet we regularly hear from families whose loved one under §841(b)(1)(C) was coded ineligible — often because staff read "drug trafficking" generically rather than reading the actual subsection in the judgment.
If the judgment shows §841(b)(1)(C), that is a strong basis to challenge an ineligibility determination in writing. The precise, quotable citation — "my judgment shows 21 U.S.C. §841(b)(1)(C), which is not an excluded offense; why am I coded ineligible?" — is much harder to brush aside than a general complaint. Our offense eligibility guide details the challenge steps.
Quantity, role, and the sentencing record
For the high-level exclusions, the analysis often depends on findings made at sentencing — drug quantity attributed, and whether the person held an aggravating role. Because these are findings in the record, the presentence report and the statement of reasons matter here in a way they do not for the offense-of-conviction analysis. This is one context where the sentencing documents genuinely bear on FSA eligibility.
Families sorting through this should gather the judgment, the statement of reasons, and the relevant portions of the PSR, and compare them carefully against the enumerated exclusion criteria. Where the record does not actually establish the aggravating facts the exclusion requires, there may be room to challenge an exclusion — a fact-specific analysis that rewards careful reading.
If the offense truly is excluded
Some drug convictions genuinely fall on the excluded side, and honesty about that saves wasted effort. But exclusion from FSA credits is not the end of the map. A person excluded from FSA credits still earns good conduct time at 54 days per year. And for drug cases specifically, RDAP — the residential drug program — offers up to a year off under a separate statute, 18 U.S.C. §3621(e), with its own eligibility rules.
For many drug-offense families, RDAP is actually the larger prize, and it runs on a different track with different exclusions. A person excluded from FSA credits may still be RDAP-eligible, and vice versa. Mapping both systems, rather than fixating on one, is how families find every available day.
The audit, step by step
Start with the judgment and read the exact statute and subsection of conviction. Compare it against the enumerated exclusions — CCE under §848, the specific high-level §841(b)(1)(A)/§960 criteria, and the death-or-serious-injury provisions. If the offense of conviction is not enumerated, the person should be earning; confirm the coding on the FSA Time Credit Assessment.
If there is a mismatch between the judgment and the coding, raise it in writing through the remedy program. If the offense is a high-level exclusion that depends on quantity or role findings, examine whether the record actually supports those findings. And in every drug case, separately check RDAP eligibility, because it is a parallel path to as much as a year off.
