Oregon Decriminalized Hard Drugs in 2020 and Reversed Course in 2024

The most interesting thing about Oregon's experiment with hard drugs is not that it failed. It is who said so. Not a sheriff, not a talk-radio host, but the state legislature, run by Democrats, which voted to undo what voters had approved.

When the people who built a thing start taking it apart, you should pay attention. This is the history of Measure 110, told in order, with the two conservative camps on drugs in mind: the ones who think prohibition is a mistake and the ones who think a society must keep saying no. Both have something to learn here, and I will tell you what.

Terms first

Measure 110 was a ballot initiative, a law proposed and passed directly by voters rather than by a legislature. It was a decriminalization measure, not a legalization measure. That distinction matters. The drugs stayed illegal. Selling them stayed a crime. What changed was the penalty for possessing a small amount for personal use, which the measure turned from a criminal offense into something much closer to a traffic ticket.

Here is the scoreboard we will track as we go: what the measure promised, what the money did, what the public saw, and what the legislature concluded.

November 2020: what the voters approved

In November 2020, Oregon voters approved Ballot Measure 110, the Drug Addiction Treatment and Recovery Act. It passed with a clear majority of the vote. The campaign pitch had two halves, and it is worth keeping them apart.

The first half was about the law. People caught with small amounts of a range of controlled substances, including heroin, methamphetamine and cocaine, would no longer face arrest and a criminal record for possession alone. The thinking was familiar from the libertarian side of the debate: a criminal record wrecks employment and housing, the drug war had been a long failure, and sending users through courts and jails does not cure addiction.

The second half was about the money. The measure promised that the savings from fewer arrests, plus a large share of the state's marijuana tax revenue, would be steered into treatment and recovery services. Voters were not simply told "stop arresting people." They were told "stop arresting people and build the treatment system that will actually help." That second half was the hinge on which the whole experiment turned.

You can accept the premise of the experiment and still ask a fair question: did the treatment arrive before the penalty left?

February 2021: the $100 citation and the hotline

The decriminalization took effect in February 2021. Under the new system, a person found with a small amount of a covered drug was not arrested. Instead the officer issued a citation, a Class E violation, which carried a fine of one hundred dollars. And here was the clever part, or the part that was meant to be clever: the fine could be waived if the person called a hotline and completed a health assessment, a screening that could connect them to services.

Think about what that design assumes. It assumes a person in the grip of a serious addiction, handed a piece of paper by a police officer, will respond to it by making a phone call and sitting for a screening. It assumes the hotline is a sensible off-ramp. And it assumes the services at the other end exist and are ready to take the caller.

Defenders had reasons to think it could work. Portugal, a country often cited by reform advocates, decriminalized personal drug possession in 2001 and paired it with administrative panels that could direct people toward treatment. Oregon's design borrowed the spirit of that approach. But the details differ in a way that turned out to matter: Portugal's panels had a mechanism to compel attention, while Oregon's citation relied on a voluntary phone call. By most accounts, only a very small share of people who received citations ever called, and many cited people simply did not respond at all, because a hundred-dollar fine with no enforcement behind it is easy to ignore. I would urge you to check the state's own published data for the current figures instead of trusting any number I could give you here.

The result was a gap. The penalty that had moved people toward courts and, sometimes, into court-supervised treatment was gone. The carrot was a phone number. In many cases there was no stick.

The money moved slowly

The second half of the promise ran into the usual reality of government: setting up a new system takes time, and the need was immediate.

The measure created Behavioral Health Resource Networks, regional groups of providers meant to deliver services, and directed state funds toward them. Standing up networks of that kind means writing rules, awarding grants, contracting with providers and hiring staff. Reporting at the time and state oversight afterward described delays in getting funds out the door and in getting services running at the pace voters expected. The state's treatment capacity, which had been thin before the measure, did not expand overnight, and there was a stretch in which the penalty had gone and the help had not yet arrived.

I do not want to be unfair. Building treatment capacity from a low base is hard anywhere, and it takes longer than a campaign cycle. But that is exactly the point. A responsible reform sequences the steps so the safety net is built before the trapdoor is opened. Oregon opened the trapdoor first. Whatever your view on drug policy, that is a design error, not an ideological one.

What the public saw

Here is where the argument gets contested, and I will state both sides.

By 2022 and 2023, residents and visitors in Portland and other Oregon cities were describing open drug use in public places, on sidewalks and in parks and near businesses, and the national press picked the story up. Business owners and neighborhood groups complained. A reasonable observer could connect the visible disorder to the loss of the old enforcement tools: when possession could not lead to an arrest, police had less leverage to move people along or into services.

The defenders of the measure replied that the picture was more complicated, and they were not wrong to say so. Drug use in public was a problem in Oregon before 2021. Overdose deaths were rising across the country as illicit fentanyl spread, and that was happening in states that had not decriminalized anything. A scholar can fairly argue that it is hard to separate the effect of the measure from the effect of the drug supply changing under everyone's feet. Fentanyl is cheap, potent and deadly, and it hit every state. It is not honest to blame Measure 110 for every overdose in Oregon, and it is not honest to pretend the measure had no effect on what the public saw on the street.

I will say what I think is the defensible reading. The measure did not cause the fentanyl crisis. But it removed the criminal penalty at a moment when the drug supply was growing deadlier, and it did so before the treatment system was ready, and the combination left the state worse equipped to respond than it might have been. Politically, voters noticed. A measure that passed with a healthy majority in 2020 had lost much of its public support within a few years.

House Bill 4002 and the reversal

In 2024, the Oregon legislature passed House Bill 4002, and it was signed into law that spring. The bill rolled back the core of Measure 110. It restored criminal penalties for possessing small amounts of the covered drugs, making simple possession a misdemeanor again, and it took effect in September 2024.

What is worth noticing is what the bill did not do. It did not simply return to the pre-2021 world. It built in deflection: a framework that encourages counties to set up programs steering people toward treatment rather than a prosecution, so that an arrest can be an offer, with a consequence behind it, instead of only a punishment. In effect, the legislature kept the treatment goal and restored the stick. That is the "carrot and stick" model, and it is a close cousin of what treatment courts and many conservative reformers have favored for decades.

It is also worth saying that the bill passed with bipartisan support, in a legislature controlled by the party that had mostly supported the original measure. It was not a partisan retaliation. It was a political acknowledgment that the first design had not delivered what was promised.

What the libertarian-minded camp should learn

Let me speak to each conservative camp in turn, because each has a lesson.

If you are on the liberty-first side, the side that believes prohibition is a costly failure, the lesson is not that you were wrong about arrests. A criminal record for possession really is a heavy penalty, and incarceration really does not cure addiction. The lesson is about sequence and design. Reform that removes a penalty without building the alternative is not liberty. It is abandonment with a good slogan. And a voluntary phone call is not a system. If you want to defend decriminalization on the merits, you have to defend a version that includes a consequence for refusing help, and you have to be willing to fund the services first. Libertarians have always said government is bad at big projects. Oregon's treatment rollout is a decent case study of that very point.

What the order-first camp should learn

If you are on the order-first side, the camp that believes society must keep saying no, the lesson is also uncomfortable. The old system did not cure addiction either. A pure arrest-and-jail approach fills cells and does little for the person who comes out the other end with a record and the same craving. The reform movement did not come from nowhere. It came from a real frustration with a model that was expensive and not very effective.

What the Oregon reversal supports is a middle path: keep the penalty, use it as leverage, and attach it to real treatment. That is not a surrender of your principles. It is how many of the best treatment courts already work, where a judge offers a choice between supervision and sentence, and where the possibility of a consequence is what keeps people in the program. If you believe the law teaches, here is the lesson: the law is a better teacher when it comes with a path out. For the history of how one conservative state arrived at a similar idea, see Texas Chose Treatment Beds Over New Prisons in 2007, and Here Is Why.

What it means for federalism

There is a constitutional lesson too, and it is the one the Founders would have smiled at.

Justice Louis Brandeis wrote in 1932 that a state may, if its citizens choose, serve as a laboratory and try novel social and economic experiments without risk to the rest of the country. Oregon was that laboratory. Voters tried something bold, it was tested in public, the results came in, and the state's own elected representatives changed course. No federal mandate was needed to make that happen, and no federal mandate would have helped. The system worked as designed: an experiment, an observation, a correction.

Now consider the counterfactual. If this had been imposed nationally, from Washington, the correction would have been far harder. Fifty states, each free to try its own approach, give the country a way to learn from mistakes at a cost that is borne by one state rather than all of them. That is the strongest conservative argument for letting states decide, whichever side of the drug debate you favor. It is the argument I made at Should Conservatives Support Drug Legalization? Both Sides Make Their Case.

Objections

"The rollback proves prohibition was right all along." It proves less than that. Oregon returned to criminal penalties, but with deflection and treatment attached. That is a hybrid, not a vindication of the old model.

"The measure was never given enough time or money." There is something to this, and it is the best defense of the original design. Treatment systems take years to build. But a policy has to be judged on the timeline voters and families actually live in, and the legislature judged that the timeline had run out.

"Fentanyl, not the law, caused the deaths." Largely true that fentanyl is the driving force of overdose deaths nationwide, and fair to say. But the question for policy is what tools a state has when fentanyl arrives, and decriminalization without an enforced off-ramp removed one of them.

For the related question of what happens when a sale ends in a death, see Should a Dealer Who Sells a Fatal Dose Be Charged With Homicide. For the broader legal framework, the Constitution page lets you read the Tenth Amendment yourself.

The case in brief

1. Measure 110, approved in November 2020, decriminalized possession of small amounts of hard drugs and promised to fund treatment with marijuana tax revenue and savings.
2. From February 2021 the penalty was a one-hundred-dollar citation waivable by calling a hotline, a design that relied on voluntary action and had little force behind it.
3. Treatment capacity lagged the penalty's removal, and public drug use became a visible political problem as the drug supply grew deadlier.
4. House Bill 4002 restored criminal penalties from September 2024 while building in deflection toward treatment, which is a hybrid of carrot and stick.
5. Both conservative camps can learn from it: reform must build the alternative before it removes the penalty, and a penalty works best as leverage toward treatment.

What you can do: look up your own state's possession statute and the deflection or drug-court programs in your county, and ask your county commissioners how many treatment beds exist.
