Oregon walked back the softer policy — and it was not even legalisation

Oregon's Ballot Measure 110 (2020) made possession of small amounts of heroin, methamphetamine, cocaine and the rest a civil violation. Sale stayed illegal. That is the third camp, not the claim. House Bill 4002, signed 1 April 2024, made those possessions a drug-enforcement misdemeanor from 1 September 2024, with jail up to six months, because the political system judged that public use, untreated addiction, and disorder had not been a success. AGAINST should not pretend 110 was a clean trial — treatment money was slow, fentanyl arrived, housing was already broken. The steelman does not need a clean trial. It needs the revealed preference of a jurisdiction that tried the softer line and reversed. Legalising all drugs is a larger step in the same direction: not only no arrest for the pouch, but a licensed product. If decriminalisation without a shop could not hold in Oregon, the shop is not the missing piece. It is a bigger version of the thing they undid. Portugal (Law 30/2000) is the named third camp: administrative sanctions for users, trafficking still a crime, a dissuasion commission. Hughes and Stevens (BJC, 2010) are the careful read — mixed, not a miracle, and still not legalisation. AGAINST can prefer Portugal to Oregon without granting a methamphetamine off-licence.

Key assumptions

  • Oregon's reversal was about the drug policy, not only about housing, fentanyl, and slow treatment spend partial
  • A failed-or-reversed decriminalisation is informative about legalisation, not only about decriminalisation partial

Red team — the strongest counters

Oregon was fentanyl plus slow treatment money, not a test of a shop

Measure 110 did not legalise sale. Treatment spend lagged. Housing was already broken. Walking it back is a political fact. It is not a finding that a licensed supply would have been worse.

Portugal held — so the specimen is the implementation, not the third camp

Hughes and Stevens are mixed, not a collapse. A dissuasion commission with treatment capacity is not Oregon's civil violation plus a street. Using 110 to kill legalisation skips the European model AGAINST says it prefers.

The fentanyl death count is what a potent opioid does in a population — a shop does not uninvent it

CDC NCHS Data Brief 549: 79,384 drug-overdose deaths in the United States in 2024. The rate fell from 2022–23, which is news, and the level is still a war. FOR says the deaths are prohibition's adulteration. AGAINST says look at what people were seeking: a stronger opioid, a stimulant that lasts, a pill that looks like medicine. A licensed product can be exactly that. Pharmaceutical opioids were legal, labelled, and sued — and still seeded a dependence cohort that illicit fentanyl then harvested. That is the closest large-country experiment in 'legal opioid supply,' and it is not a FOR specimen. Worldwide the synthetic-opioid disaster is concentrated in North America; UNODC is the global book. AGAINST does not need every country to have fentanyl to make the point about 'all.' Legalise heroin and fentanyl analogues in a shop, in a population that already learned to like them, and quality control removes the surprise without removing the receptor. Alcohol's legal deaths are the other warning, not the warrant. Mill's harm principle stops at the other people in the car, the child, and the partner. Those others are in Nutt's harm-to-others column for a reason.

Key assumptions

  • A large share of overdose deaths would continue under a legal, labelled opioid and stimulant supply partial
  • Prescription-opioid history is a fair analogue for a recreational legal opioid market partial

Red team — the strongest counters

The labelled opioid crisis was over-prescription, not a recreational shop

Purdue is a marketing-and-dose scandal inside medicine. A recreational licence with age-gates, no advertising, and no 30-day bottle is a different design. Using OxyContin to kill any legal opioid is a smash.

The death count is still concentrated where the powder was a surprise

UNODC's geography: the synthetic-opioid disaster is North American. A worldwide claim cannot cash 79,384 as the global cost of 'all.' Adulteration remains the mechanism in that specimen.

Nutt's own table says heroin, crack and meth are the worst for the user

Read the Lancet 2010 paper the other column cites. Nutt, King and Phillips: to the individual, crack (37), heroin (34) and methamphetamine (32) are the most harmful drugs on their scale. Alcohol leads overall because of harm to others and because it is already everywhere. That is an argument for taxing drink. It is not an argument for putting methamphetamine next to it. Tobacco is legal and still a mass killer — AGAINST can grant that and say: two legal catastrophes are not a warrant for a third, fourth, and fifth. The claim is all currently banned recreational drugs. Cocaine, meth, heroin, and the rest of the list are in. A pharmacy model that treats those like isotretinoin is still a supply. A shop model is a marketing department. Either way, 'all' means the drugs whose individual-harm scores are why they were banned. Consistency with beer is a smash across that difference.

Key assumptions

  • Individual-harm scores are the right object for a ban, not overall scores inflated by alcohol's installed base untestable
  • Legal supply would raise, not merely relocate, the number of people taking the high-individual-harm drugs partial

Red team — the strongest counters

Legal alcohol's harm-to-others is the warning, not the ceiling

If beer scores 46 on harm-to-others because it is legal and common, adding a legal heroin would raise heroin's overall rank, not leave Nutt's table fixed. Using today's individual scores as a freeze-frame is the trick.

The schedule is ugly and still not a reason to add the worst-for-the-user drugs

AGAINST can grant that LSD and MDMA are over-scheduled relative to alcohol. The claim is all. Meth, crack and heroin are why 'all' is the claim people actually fight.

Heroin-assisted treatment is a clinic, not a shop — and it still sits under a ban

Perneger's Geneva RCT had 51 people. The Swiss PROVE cohort was on the order of a thousand. The Dutch, German, Spanish, Canadian and English trials were for chronic, treatment-refractory opioid users, with supervised use and wraparound care. Crime and street heroin fell in those arms. AGAINST can grant every table. The inference FOR wants — therefore legalise all drugs — does not follow. HAT is the opposite of a retail licence: eligibility, daily attendance, no take-home in the classic design, a doctor. It is how a ban treats the people the ban already failed. Expanding it is compatible with AGAINST. Turning it into a warrant for cocaine shops, methamphetamine, MDMA, and psychedelics for all adults is a smash. Portugal again: users diverted, sellers prosecuted. Switzerland kept heroin illegal for everyone not in the programme. Those are the working European models. They are not the claim.

Key assumptions

  • Clinic-gated HAT can be scaled to the people who need it without a general legal market partial
  • The crime drop in HAT is not evidence that a shop would drop crime in the whole population partial

Red team — the strongest counters

A clinic is already a legal supply — the rest is haggling

Once the state puts diacetylmorphine in a syringe, 'heroin cannot be in the legal world' is false. Last-line is how you start. Calling that a different object is how prohibition keeps the street for everyone else.

Switzerland kept the ban and kept the deaths it didn't treat

People not in the thousand-person cohort still bought street heroin. That is the cost of the gate AGAINST is defending. HAT as exception is not a population policy.

A legal industry does to a drug what it did to tobacco

Alcohol and tobacco are not accidents that happened to be legal. They are industries. Tobacco's playbook — youth targeting, dose engineering, captured regulators, decades of delay — is the specimen of what a legal recreational market does with an addictive product. Cannabis legalisation, where it has happened, grew a commercial layer of high-THC products, shops, and political money; it did not remain a home grow. AGAINST does not need Colorado to be a disaster. It needs the mechanism: legalise all drugs and you do not get a grim pharmacist for methamphetamine. You get, after a lag, a firm that has discovered the heavy user is the profit. Heroin and cocaine are worse substrates for that firm than cannabis. Harm-reduction FOR will say regulation can ban ads and cap potency. Tobacco was regulated. It still ran the century. The claim is not a Swiss clinic for a thousand people who failed methadone. It is a legal supply for adults of the whole list. Clinics are a medical exception under a ban. A market is the ban's opposite.

Key assumptions

  • Commercial cannabis and historic tobacco are fair analogues for a legal cocaine or methamphetamine market partial
  • Regulation cannot hold a potency-and-marketing line against firms whose profit is the heavy user partial

Red team — the strongest counters

A pharmacy gate is not a tobacco company

HAT, isotretinoin, and methadone are legal supplies without a flavour-and-billboard industry. The tobacco playbook needs advertising and off-licence retail. Those are design choices, not destiny of 'all.'

Cannabis shops are not a methamphetamine forecast

High-THC retail is a real commercialisation. Cocaine and meth have different users, different harm, and would face a nastier regulator if they were ever licensed. Analogy is not a trial.

Unknown dose is what you get when the seller cannot be sued

The North American overdose spike of the 2010s–2020s was not a sudden love of dying. It was a supply shock: illicitly manufactured fentanyl and analogues in powders and pills that the buyer thought were something else. CDC NCHS: 79,384 drug-overdose deaths in the United States in 2024, down from the 2022 peak but still a wartime number. FOR should not pretend the rest of the world has the same fentanyl market — UNODC's World Drug Report is the global book, and the synthetic-opioid disaster is concentrated. The mechanism travels. A ban removes civil liability, brand, and assay. Alcohol Prohibition in the United States gave people methanol; repeal gave them bottles with a percentage on the side. Portugal-style decriminalisation (Law 30/2000: personal possession an administrative offence, sale still illegal) is a third camp, named here so it is not stuffed into FOR. It leaves the mixer in business. Legalising all drugs is the claim that the state would rather license a dose than hunt the person who swallowed one. Quality control is not a full answer to addiction. It is an answer to dying of a surprise.

Key assumptions

  • A legal supply would be clean enough, and cheap enough, to pull users off the adulterated market rather than sit beside it partial
  • Overdose deaths under prohibition are mostly a product of unknown potency, not of the drugs being used at all partial

Red team — the strongest counters

Pharmaceutical opioids were labelled and still killed

The closest large legal opioid supply was prescription. Quality control did not prevent a dependence cohort. Fentanyl then harvested it. 'Unknown dose' is not the whole death count.

People seeking a stronger hit will still mix

A licensed powder with a percentage on the side does not remove the demand for a bigger percentage. Adulteration can fall and deaths can stay if the legal product is strong, cheap, and everywhere.

Clinics already hand heroin to people who failed methadone

Perneger, Giner, del Rio and Mino (BMJ, 1998) randomised Geneva patients who had failed conventional treatment to a heroin-maintenance programme versus a wait; illicit-drug use, health, and crime moved in the treated arm. The Swiss PROVE cohort was larger — on the order of a thousand people in the mid-1990s — and Switzerland kept the clinics. Randomised trials followed in the Netherlands (van den Brink), Germany, Spain, Canada (NAOMI), and England (RIOTT / Strang). This is not a nightclub. It is a medical supply of a drug the law still treats as contraband for everyone else. FOR's step is small to state and large to swallow: if the state can put diacetylmorphine in a syringe for the hardest cases, the claim that 'heroin cannot be in the legal world' is already false. All-drugs legalisation is the same idea without the clinic-only ration — pharmacy, licensed shop, or prescription, differentiated by harm. Portugal remains the third camp: users are not imprisoned, sellers still are. Oregon Measure 110 was also decriminalisation, not legalisation, and its 2024 walk-back (HB 4002) is a specimen AGAINST will use. FOR's reply belongs here: Oregon left the black market intact. A clinic or a licensed product is the thing Oregon did not try.

Key assumptions

  • A tiny, tightly gated medical programme for treatment failures tells you something transferable about a legal retail market for all adults partial
  • Crime drops in HAT are from the legal supply, not from the extra services wrapped around the trial partial

Red team — the strongest counters

Fifty-one Genevans are not a retail market

HAT is last-line, supervised, no take-home in the classic design. Inferring 'all drugs, all adults' from treatment failures in a clinic is the smash this page is supposed to refuse.

The crime drop may be the wraparound, not the molecule

HAT trials come with services, daily attendance, and a break from the street. That is not a finding about a shop. Oregon left the black market intact — and also failed as decriminalisation. Both can be true.

The killing in producer and transit countries is a prohibition cost

When Felipe Calderón sent the army after the cartels in late 2006, Mexico's official count of drug-trafficking-related killings in the next four years passed 34,000; later years were worse, not better. Homicide is not only Mexico. Producer and transit states in the Andes, Central America, and parts of the Caribbean and West Africa have lived for decades with organisations that exist because a rich-country ban makes a plant worth more than coffee. FOR can grant that some of those men would rob anyway. The steelman is that a global illegal market with retail margins that only a ban can create is what funds the armies, the graves, and the captured towns. Legal alcohol has drunks and tax stamps. It does not have a second government with trucks of cash. Colombia's violence fell when policy and markets shifted; it did not fall because cocaine became healthy. The claim is legalise all drugs, including the ones whose prohibition currently pays the sicario. A cannabis carve-out leaves the cocaine and meth trades standing.

Key assumptions

  • A large share of that homicide is caused by illegality of the trade, not by the pharmacology or by general state weakness partial
  • A legal, taxed supply in rich countries would actually shrink the black market in poor ones rather than sit beside it partial

Red team — the strongest counters

A US shop does not disarm a Mexican plaza

Homicide has guns, local rackets, and other illegal markets. Legal cocaine in rich countries can sit beside remaining bans on production. The 34,000 is not a coefficient on the claim.

Producer states can still prohibit the plant

Legalisation is usually a consumer-country statute. Bolivia, Colombia, and Mexico would still have a policy choice — and a remaining export market wherever the ban holds. The sicario's P&L is not automatically zero.

The law already legalises two of the most harmful drugs

Nutt, King and Phillips (Lancet, 2010) asked a UK expert panel to score twenty drugs on sixteen harms to users and to others. Alcohol came first overall (score 72), above heroin (55) and crack (54). To the user, crack, heroin and methamphetamine were worse; alcohol's rank is driven hard by harm to others — violence, accidents, family — and by how many people drink. FOR should say that out loud. The load-bearing claim is not 'heroin is safer than beer.' It is that a legal regime that sells alcohol and tobacco while criminalising drugs that score lower, or score higher only because they are sold by gangs, is not tracking harm. Tobacco is legal and still kills at industrial scale. The consistent policy is to regulate, tax, age-gate, and advertise-limit the whole list, the way we already pretend to do for the two legal ones — not to pick a folkloric subset. Cannabis-only legalisation is not this claim. All currently banned recreational drugs is.

Key assumptions

  • A harm ranking built by experts in a country where alcohol is already cheap and prevalent is a fair map of 'which drugs deserve a ban' partial
  • Legal alcohol and tobacco are the right moral baseline, rather than mistakes that should be reversed untestable

Red team — the strongest counters

Alcohol's overall score is an installed base, not a licence to add meth

Nutt's 72 is harm-to-others times how many people drink. Heroin, crack and meth lead for the user. Legalising those is how you grow their harm-to-others column, not how you honour a ranking.

Two legal catastrophes are the argument against a third

Tobacco is the specimen of what a legal addictive market does. Consistency that says 'therefore cocaine' is a smash across the difference in individual-harm scores.

All means the rest of the list, not a cannabis carve-out

John Stuart Mill's harm principle is the old sentence: the state may stop you harming others; it may not stop you harming yourself as an adult. Alcohol is the live application. FOR does not need Mill to be last week's RCT. It needs the admission that 'all drugs' is what the principle says, and that cannabis-only statutes are a political halt, not a moral line. A legal regime can still be harsh on a product — age 21, no advertising, pharmacy-only for opioids, licensed rooms for smoked stimulants, prescription for the rest — and be legalisation rather than a ban. That is how we treat alcohol versus cough syrup versus isotretinoin. The claim is that currently banned recreational drugs leave the criminal law as the first tool. Portugal is the named third camp: no prison for the user, sale remains a crime. Decriminalisation is not legalisation. FOR's remaining step is the supply. People already use the whole list. The law decides whether the supply is a firm with a licence or a gang with a gun. 'All' is not a slogan to be softened into 'the safe ones.' It is the claim.

Key assumptions

  • Adult self-harm is not a sufficient reason for a criminal ban, even for drugs that wreck a minority of users untestable
  • Differentiated legal supply (pharmacy vs shop vs prescription) can be built for the whole list, not only for cannabis and alcohol partial

Red team — the strongest counters

Harm to others is not self-regarding

Mill stops at the child, the partner, and the person in the other car. Nutt's harm-to-others column is that stop. 'All' includes the drugs that wreck those others at a higher rate per user.

Differentiated regulation is a hope, not a design that has been built for meth

Pharmacy-only cocaine is a sentence. A firm, a lobby, and a heavy-user segment are the equilibrium of every other legal addictive market. 'All' does not get to assume the grim pharmacist.
