When a judge sentences someone to prison, most people assume the judge has weighed the evidence, considered the person's history, and made a reasoned decision. With mandatory minimums, that assumption falls apart. Under these laws, a judge's hands are tied. The law sets the sentence. The judge reads it aloud. And a person goes to prison for a fixed number of years no matter what else is true about their life, their case, or their circumstances.
This is not a minor policy quirk. It is one of the central engines of mass incarceration in the United States. Millions of families have been separated by sentences driven not by judicial wisdom but by mandatory minimums written decades ago in a political climate defined by fear rather than evidence.
In 2026, the conversation about reforming these laws is louder than ever. This article explains how mandatory minimums came to be, who they have harmed the most, why the evidence against them is overwhelming, and what advocates, legislators, and states are pushing for instead.
What Are Mandatory Minimums
A mandatory minimum is a law that requires a judge to sentence a convicted person to at least a specific number of years in prison. The judge cannot sentence below that floor regardless of mitigating circumstances. They cannot account for whether the person was a first-time offender, played a minor role in a larger scheme, struggled with addiction, or had strong community ties and family support.
Mandatory minimums exist at both the federal and state level. Federal mandatory minimums are particularly severe and apply most heavily to drug offenses, firearms offenses, and certain sex offenses. Under federal law, a person convicted of possessing five grams of crack cocaine with intent to distribute faces a mandatory five-year federal prison sentence.
The prosecutor holds enormous power under this system. The charges a prosecutor files determine which mandatory minimums apply. This shifts power away from judges and places it in the hands of those who negotiate plea deals. The result is a system where the courtroom decision often happens in a prosecutor's office, not before a judge.
History: How We Got Here
Mandatory minimum sentencing laws are not new. Early versions existed in the United States as far back as the 19th century. But the laws that shape today's federal prison population were largely born in the 1970s and accelerated dramatically in the 1980s.
The political backdrop was a declared "war on drugs." Crime rates were rising and public fear was real. Politicians from both parties competed to appear tough on crime. The result was a cascade of legislation that prioritized punishment over rehabilitation and rigid sentences over judicial judgment.
The Anti-Drug Abuse Act of 1986 was a turning point. Passed in the wake of public grief over athlete Len Bias's death, which was attributed to cocaine use, the law created severe mandatory minimums for drug offenses. Critically, it set dramatically different thresholds for crack cocaine versus powder cocaine. Crack, associated in the public mind with Black urban communities, triggered mandatory sentences at quantities 100 times lower than powder cocaine. That disparity would shape federal sentencing for more than two decades.
The 1994 Crime Bill went further, tying federal funding to states that adopted "truth in sentencing" laws requiring people to serve at least 85 percent of their sentence. The federal prison population exploded. States followed suit with their own mandatory minimums. The system that exists today was built brick by brick during this era.
Who Bears the Heaviest Burden
The disproportionate impact of mandatory minimums on Black and Latino communities is not a disputed point. It is documented in federal sentencing data and acknowledged by federal courts, the U.S. Sentencing Commission, and bipartisan policy organizations.
The crack-to-powder cocaine disparity embedded in the 1986 law meant that two people carrying chemically similar substances faced wildly different sentences based largely on which form of the drug they possessed and which communities those forms were most associated with. The Fair Sentencing Act of 2010 reduced that disparity from 100:1 to 18:1. The First Step Act, passed in 2018, made that change retroactive, allowing people already serving sentences under the old ratio to seek relief.
The retroactivity provision of the First Step Act was significant. Thousands of people petitioned for sentence reductions. But the 18:1 disparity still exists. Many advocates argue that full parity, a 1:1 ratio, is the only just outcome.
Beyond race, mandatory minimums hit low-income people hardest. Wealthy defendants often have access to attorneys who can negotiate plea deals that avoid mandatory minimums. People without resources are more likely to plead guilty to charges that carry mandatory floors. The sentences themselves pull people out of the workforce, damage families, and create cycles of poverty that pass across generations.
Women have also been seriously harmed by mandatory minimums, particularly those charged based on the conduct of a partner or family member. Because mandatory minimums attach to charges rather than culpability, a person who knew about a drug operation but played no active role can receive the same sentence as someone who ran it.
Why Mandatory Minimums Don't Work
The original argument for mandatory minimums rested on two claims. First, that certainty of punishment deters crime. Second, that keeping people incarcerated for fixed long terms protects public safety by incapacitation.
Neither claim has held up under scrutiny.
The U.S. Sentencing Commission has published multiple reports examining mandatory minimums and their relationship to recidivism and public safety. The findings consistently show that mandatory minimums do not demonstrably reduce drug trafficking or violent crime. Drug markets are resilient. When one person is removed and given a decade-long sentence, another person fills that role. The supply chain continues.
Research on deterrence consistently shows that it is the certainty of getting caught, not the severity of punishment, that drives deterrence effects. Adding five more years to a mandatory sentence does not meaningfully change the calculus of someone who believes they will not be caught.
What mandatory minimums do achieve is prison population growth. The federal Bureau of Prisons has operated over capacity for years. A significant portion of that population is serving time under mandatory minimum statutes. These are not dangerous individuals requiring indefinite incapacitation. Many are people convicted of nonviolent drug offenses who pose little ongoing risk to their communities.
The financial cost is staggering. Incarcerating one person in the federal system costs tens of thousands of dollars per year. Mandatory minimums force taxpayers to fund sentences that do not improve safety, do not rehabilitate, and do not address the underlying issues that lead to crime in the first place.
Judges themselves have pushed back. Many federal judges have spoken publicly about the injustice of being required to impose sentences they consider unjust. Some have resigned from the bench in protest. The judicial community's frustration with mandatory minimums spans the ideological spectrum. Conservative judges committed to judicial discretion and liberal judges focused on racial equity have both objected to laws that strip courts of their core function.
What Reformers Want Instead
Criminal justice reform advocates in 2026 are not simply calling for abolishing mandatory minimums overnight. The most serious proposals focus on structural changes that restore fairness without abandoning accountability.
Here are the core reform proposals gaining momentum:
- Restoring judicial discretion: Reformers want judges to be able to depart below mandatory minimums when they find compelling circumstances. This does not mean eliminating guidelines. It means allowing a judge to say "this sentence does not fit this person" and explain why on the record.
- Expanding safety valve provisions: Federal law currently includes a limited "safety valve" that allows certain low-level, nonviolent drug offenders to receive below-minimum sentences if they meet specific criteria. The First Step Act expanded those criteria slightly. Reformers want a broader safety valve that reaches more people and applies to more offense categories.
- Retroactive relief: Many people are currently serving sentences that would be shorter under any reformed law. Retroactivity provisions allow those individuals to petition courts for sentence reductions. The First Step Act included a retroactivity provision for the crack-powder disparity fix. Reformers want that principle extended broadly.
- Eliminating stacking: "Stacking" refers to charging multiple counts of the same or related offenses to compound mandatory minimums. A person can face decades in prison through stacking even when the underlying conduct is relatively limited. Reform advocates want rules that prevent prosecutorial overreach through stacking.
- Evidence-based sentencing guidelines: Rather than rigid floors, reformers propose guidelines informed by risk assessment, rehabilitation potential, and offense severity that give judges a structured framework without removing their ability to exercise judgment. The PATTERN risk assessment tool used by the Bureau of Prisons in First Step Act implementation is one model, though advocates note it requires ongoing scrutiny for racial bias in its inputs.
What States Are Doing Differently
States have more flexibility than the federal system, and several have used that flexibility to move away from rigid mandatory minimums.
New York's Rockefeller Drug Laws were among the most severe mandatory minimum regimes in the country. Passed in the 1970s, they mandated lengthy prison terms for drug offenses. After decades of advocacy, New York passed reforms that gave judges substantially more discretion and allowed people already serving Rockefeller sentences to seek resentencing.
New Jersey eliminated mandatory minimums for a wide range of drug offenses as part of broader sentencing reform legislation. The state found that removing mandatory minimums did not increase crime rates. Courts were able to sentence based on individual circumstances without public safety deteriorating.
Michigan repealed most of its mandatory drug sentences years ago and saw its prison population drop substantially. The savings were redirected toward drug treatment programs and community supervision, approaches that address the root causes of drug offenses rather than simply warehousing people.
Connecticut, Mississippi, and other states from different political traditions have all passed legislation reducing mandatory minimums, often with bipartisan support driven by cost concerns as much as equity concerns. Fiscal conservatives and civil rights advocates have found common ground in recognizing that mandatory minimums are expensive and ineffective.
These state experiments provide real data. They show that reducing mandatory minimums does not cause crime to rise. They demonstrate that courts can exercise discretion responsibly. They offer a roadmap for federal reform that skeptics can examine with actual outcomes rather than projections.
How Families Can Get Involved
If your loved one is serving time under a mandatory minimum, you are not powerless. There are specific steps you can take right now.
First, find out whether your loved one may be eligible for relief under existing provisions. The First Step Act created mechanisms for sentence reductions for certain people convicted of drug offenses. An attorney with federal criminal experience can assess eligibility. Many legal aid organizations offer free consultations for families who cannot afford private counsel.
Second, connect with advocacy organizations working directly on sentencing reform. Groups like the ACLU's National Prison Project, the Sentencing Project, and FAMM (Families Against Mandatory Minimums) have been working on these issues for decades. FAMM in particular was founded by a family member of someone serving a mandatory minimum sentence and brings direct lived experience to its advocacy work.
Third, engage your elected officials. Members of Congress need to hear from constituents who have been directly affected by mandatory minimums. Personal stories carry weight that data alone cannot. Write letters. Attend town halls. Connect with organizations that facilitate meetings with Congressional offices.
For reentry planning and resources once your loved one is released, DrPrison.org offers guidance on navigating the reentry process, accessing benefits, and rebuilding life after incarceration. For a first-person perspective on what reentry actually looks like, KenGaughan.com offers honest writing from someone who has lived it.
If you or a family member is struggling with the mental health toll of incarceration or the reentry process, the 988 Suicide and Crisis Lifeline is available 24 hours a day by calling or texting 988. The weight families carry during incarceration is real. You do not have to carry it alone.
Mandatory minimums were built over decades by political decisions made in a climate of fear. Changing them will also take time. But the evidence is clear, the coalitions are growing, and the people most harmed by these laws are increasingly at the center of the conversation about how to fix them. That is how real change begins.
