Nearly Half of States Have Scaled Back Mandatory Minimums. Here's the Real Data.

The official federal numbers, straight from the U.S. Sentencing Commission

Mandatory minimum sentencing laws require judges to impose a specific minimum prison term for certain offenses, removing judicial discretion to weigh individual circumstances. According to the U.S. Sentencing Commission's own official data, of 61,678 federal cases reported in fiscal year 2024, 14,964 involved an offense carrying a statutory mandatory minimum, meaning 15.9% of all federally sentenced individuals were subject to a mandatory minimum penalty at sentencing.

These laws trace back significantly to the Anti-Drug Abuse Act of 1986, which established some of the most well-known federal mandatory minimums: a 5-year minimum for offenses involving quantities as small as 5 grams of crack cocaine or 1 kilogram of heroin, and a 10-year minimum for larger quantities, sentences that apply regardless of an individual defendant's specific role or circumstances in the offense.

A genuinely large, active reform movement is underway, mostly at the state level

The Sentencing Project's 2025 update to its "Second Look Movement" report describes state-level sentence review reforms, laws allowing courts to reconsider lengthy sentences after a set period of time served, as having gained traction in half of all U.S. states. "Prosecutor-Initiated Resentencing" (PIR), a specific reform mechanism allowing prosecutors themselves to request a sentence review, has facilitated more than 1,000 resentencings nationwide to date, with Utah becoming the newest state to adopt this approach.

Specific 2025 state reforms documented by The Sentencing Project include: Maryland allowing emerging adults (ages 18-24) to seek sentence reductions after 20 years served, affecting an estimated 600 people; Michigan extending mandatory life without parole relief from those who were 18 or younger at the time of their offense to those who were 19 or 20; and Delaware expanding both second-look eligibility (25+ years served) and compassionate release (age 60+, 15+ years served).

Almost half of states, and the federal government itself, have already scaled back drug-related mandatory minimums specifically

• Almost half of all states, along with the federal government, have reduced or eliminated some mandatory minimums specifically tied to drug offenses, according to Sentencing Project analysis
• Colorado, Iowa, and Washington now specifically forbid mandatory minimums for certain categories of offenses outright, rather than just narrowing their application
• The federal First Step Act, a rare instance of federal-level reform, applies certain sentencing changes retroactively, meaning people already serving time under older, harsher provisions became eligible for reduced sentences after the law's passage
• "Safety valve" provisions, which allow judges to bypass a mandatory minimum in specific qualifying circumstances (such as a defendant's lack of significant prior criminal history), are being adopted by a growing number of states as a middle-ground mechanism short of eliminating mandatory minimums entirely

Federal policy is moving in a genuinely different direction from this state-level trend

The Sentencing Project specifically describes the current presidential administration's efforts to roll back local criminal legal reforms, particularly in Washington, D.C., as "deeply at odds" with the broader state-level reform trend documented in its 2025 report. This creates a genuine, active divergence: while a majority of individual states continue expanding sentence review and reducing mandatory minimum applications, federal-level policy under the current administration has moved toward reversing, not extending, similar reforms in jurisdictions under more direct federal influence.

The core disagreement

Mandatory minimum supporters generally argue these laws ensure consistent, predictable sentencing regardless of which judge happens to hear a case, and that removing judicial discretion prevents unwarranted leniency for serious offenses, framing them as a straightforward public safety and consistency measure. Reform advocates generally argue mandatory minimums prevent judges from considering legitimate individual circumstances (a defendant's specific role, criminal history, and personal circumstances), pointing to research cited by reform organizations finding no clear link between extreme sentence length and improved public safety outcomes, and note that reduced mandatory minimum application in nearly half the country hasn't produced the crime increases opponents of reform have warned about. Both sides broadly agree state-level reform activity has genuinely accelerated in recent years, the real disagreement is over whether that represents overdue correction or a concerning weakening of sentencing consistency and deterrence.
