Modern Drug Reform: Decriminalization and What Comes Next

Drug reform has produced real change — marijuana is legal in half the country, the crack-powder sentencing disparity is narrowed, naloxone is widely available — but it has not produced a coherent replacement for the enforcement framework it has partially dismantled. In November 2020, Oregon voters passed Measure 110, making Oregon the first U.S. state to decriminalize possession of all drugs. Three years later, under pressure from a fentanyl crisis and rising visible drug use in Portland, the Oregon legislature partially reversed it.^1^ That arc — sweeping ambition, real-world complications, partial retreat — is a useful lens through which to read the current state of drug reform in America.

Where the Reform Movement Actually Came From

The modern drug reform movement grew from several converging streams. The harm reduction movement, which emerged in the 1980s in response to HIV transmission through shared needles, established the foundational idea that reducing the negative consequences of drug use was a legitimate public health goal even when abstinence was not achieved. Needle exchanges, naloxone distribution, and safe consumption sites all grew from this framework.

The academic criminology and public health literature, accumulating through the 1990s and 2000s, produced a consistent finding: drug incarceration did not reduce drug use rates, mandatory minimums did not deter trafficking, and the countries that had shifted away from criminal enforcement toward public health approaches — Portugal, most notably — had seen reductions in addiction, HIV transmission, and drug-related mortality without corresponding increases in drug use.^2^

Portugal’s 2001 decriminalization of all drug possession for personal use became the most-cited international data point in American drug reform debates. Under the Portuguese model, possession was shifted from criminal to administrative violation; the penalty was a referral to a dissuasion commission that could recommend treatment, community service, or a fine. Portuguese drug-related HIV infections declined from 52 percent of all new cases in 2000 to 7 percent by 2015. Drug-related deaths fell substantially.

What Has Actually Changed in the United States

The most significant drug reform of the past two decades is marijuana legalization, which has proceeded state by state outside the federal framework. Colorado and Washington became the first states to legalize recreational marijuana in 2012. By 2024, 24 states and the District of Columbia had legalized recreational marijuana, and 38 states had medical marijuana programs. The federal government still classifies marijuana as a Schedule I substance, creating a legal conflict between state and federal law that has produced ongoing complications in banking, employment, and interstate commerce.

At the federal level, the Fair Sentencing Act of 2010 reduced the crack-powder sentencing disparity, and the First Step Act of 2018 made those changes retroactive and introduced several additional sentencing reforms — allowing more defendants to petition for early release, expanding the “safety valve” provision that lets low-level drug offenders avoid mandatory minimums, and adding good-time credit for participation in rehabilitative programs. The First Step Act was the first significant bipartisan federal criminal justice reform in decades. It was also modest: it did not eliminate mandatory minimums, did not reclassify any substances, and did not address the structural conditions that drove the drug war’s racial disparities.

How the Fentanyl Crisis Disrupted the Reform Argument

The drug reform conversation of the 2010s was taking shape in a relatively stable environment. The 2020s arrived with fentanyl, which has disrupted the reform framework in ways that are still being sorted out. Fentanyl — a synthetic opioid approximately 100 times more potent than morphine — began appearing in the heroin supply in significant quantities around 2013 and accelerated rapidly after 2016. By 2021, drug overdose deaths in the United States exceeded 107,000 annually, the largest single-year total ever recorded, with synthetic opioids — primarily illicit fentanyl — involved in approximately 66 percent of those deaths.^1^

The fentanyl crisis has complicated the decriminalization argument because fentanyl is not a drug being used recreationally in the traditional sense. It is being consumed unknowingly by people who believe they are using heroin, pressed into counterfeit pills that look like legitimate pharmaceuticals, and mixed into cocaine, methamphetamine, and other drugs at levels that produce accidental fatal overdoses. Oregon’s experience with Measure 110 reflected this complication. In early 2024, the Oregon legislature passed HB 4002, recriminalizing drug possession while maintaining some public health infrastructure. The reform that had been hailed as a model was partially rolled back within three years of implementation.

What “Decriminalization” Actually Means

The term “decriminalization” covers a range of policies that are frequently conflated. True decriminalization, as in the Portuguese model, removes criminal penalties for personal possession while maintaining prohibition on supply. Diversion programs route drug arrests into treatment rather than prosecution. Drug courts allow defendants to avoid conviction through supervised treatment completion. Legalization — the model applied to marijuana in several states — goes further, establishing a regulated commercial market.

None of these approaches — even the most comprehensive — addresses the upstream supply conditions. As long as fentanyl and other synthetic drugs are produced and distributed through illegal markets, the supply chain will be dangerous in ways that individual possession policy cannot fully address. The reform debate in the United States has not yet developed a coherent framework for the legal status of supply — the trafficking, manufacturing, and distribution side of the equation that is responsible for the drug’s availability.

Why Drug Reform Still Can’t Find a Stable Political Coalition

Drug reform has achieved unusual bipartisan support in some areas and remained deeply contested in others. Marijuana legalization has support from libertarian-leaning Republicans and progressive Democrats. Sentencing reform found enough bipartisan consensus to produce the First Step Act under a Republican administration. But broader reform — rescheduling substances, expanding harm reduction, eliminating mandatory minimums — faces continued resistance from law enforcement lobbies, prosecutors’ associations, and the political instinct to never appear “soft on crime.”

The 2024 DEA proposal to reschedule marijuana from Schedule I to Schedule III — which would acknowledge its accepted medical uses and allow research to proceed more freely — marked the first significant federal movement on marijuana scheduling in fifty years. The rescheduling process was ongoing as of 2024 and had not been completed.

The drug reform era has produced real change: lower incarceration rates, reduced sentences for some offenders, legal marijuana in half the country, naloxone more widely available than at any point in American history. The harm reduction movement knows what it wants and has decades of evidence behind its positions. The political system has moved toward it slowly, unevenly, and with frequent reversals. The people most affected by the drug war’s consequences are watching both the progress and the retreats from communities that still bear the structural damage of fifty years of mass incarceration policy.
