The History of Safer
Imagine writing the history of civilisation not through kings, wars, borders, revolutions or empires, but through something much simpler: the history of safer.
Stone became bronze, horses gave way to cars, candles gave way to electricity, and open fires moved into controlled stoves. Look closely enough at human progress and a pattern begins to appear. We rarely solve problems by eliminating the underlying human need. We solve them by finding a better way to meet it. We did not eliminate the need for warmth; we made heating safer. We did not eliminate the need for light; we made lighting safer. We did not eliminate the need for transport; we made transport safer. We did not eliminate the need to build, travel, eat, work, communicate or explore; we developed technologies and systems that reduced the dangers involved in doing those things.
Civilisation, in that sense, is partly a history of substitution. Dangerous becomes less dangerous, crude becomes controlled, unregulated becomes standardised, primitive becomes engineered and known hazards become manageable hazards. That is how societies usually advance, not by waiting for perfection, but by moving toward something better.
And that is why the question of smoking is so important.
For more than a century, cigarettes became embedded in social life on an extraordinary scale. They were cheap, convenient, portable, widely advertised and deeply normalised. Millions became dependent on nicotine through a delivery system that also happened to be exceptionally harmful: burning tobacco and repeatedly inhaling the smoke.
Once the consequences became undeniable, public health responded with enormous energy through advertising restrictions, tax increases, smoke-free laws, health warnings, education campaigns, quitlines, cessation medications, age restrictions, plain packaging and restrictions on promotion. All of these measures were built around an indisputable truth: smoking kills.
And they achieved enormous good. Smoking rates fell dramatically across many developed countries, social norms changed, cigarette advertising largely disappeared, smoking indoors went from ordinary to unacceptable and millions quit. It is one of the major public-health achievements of the modern era.
But success created its own intellectual problem. The message became so simple, so entrenched and so culturally powerful that the distinctions underneath it sometimes disappeared. Smoking is dangerous became tobacco is dangerous, tobacco is dangerous became nicotine is dangerous, nicotine is addictive became nicotine use itself is the central problem, and eventually, in parts of public debate, the delivery system almost ceased to matter.
That is where the history of safer becomes relevant, because the greatest danger in smoking is not that smokers enjoy nicotine. It is that they obtain it by inhaling the products of combustion.
That distinction changes almost everything.
The cigarette is, fundamentally, a combustion technology. You light dried plant material on fire, create smoke containing a complex mixture of chemicals, and inhale that smoke repeatedly into the lungs, often dozens or hundreds of times a day, over many years. Once you describe smoking mechanically rather than morally, the problem becomes easier to understand. The question is no longer simply, “How do we eliminate nicotine?” It becomes, “How do we eliminate the need to burn tobacco to obtain nicotine?”
That is an entirely different problem, and history gives us a remarkably consistent answer: we replace the dangerous delivery system.
Human progress has done this again and again.
Consider fire. Fire transformed civilisation because it provided heat, protection and the ability to cook food, but open fire inside homes was also profoundly dangerous. Smoke filled rooms, sparks caused burns, houses caught fire and respiratory exposure was constant. The solution was not to declare warmth morally unacceptable. We built chimneys, then enclosed fireplaces, then stoves, then gas heating, then electric heating, then heat pumps and modern climate-control systems.
At every stage, the objective remained the same: preserve the benefit while reducing the harm. No sensible person looked at the first stove and said, “This is not completely safe, therefore open fires should remain the standard.” We improved the stove, improved ventilation, improved fuel systems, created building codes and developed standards. The safer alternative did not need to be perfect to represent progress. It only needed to be substantially better than what it replaced.
That principle sounds obvious until nicotine enters the conversation.
Consider lighting. For centuries, homes were illuminated by flames through candles, oil lamps and gas lamps. Each worked, and each also carried obvious danger through smoke, soot, indoor pollution, fire and explosions. Then electricity arrived. Early electrical systems were far from harmless. Wiring was primitive, insulation failed, fires occurred, and people were electrocuted.
Had society applied a zero-risk standard to electricity, we might have remained with candles. Instead, we recognised direction. Electricity could provide the same human benefit, light, without requiring a flame in every room. So we improved electrical safety through circuit breakers, insulation, grounding, standards, licensing and safer appliances. The presence of risk did not invalidate the technology. The relevant comparison was not electricity versus perfection; it was electricity versus the technology it was replacing.
That is one of the most important ideas in all of harm reduction: compared with what?
That question has shaped progress across almost every area of life. Cars are dangerous, but compared with walking beside a highway, with horses pulling heavy vehicles through crowded cities, or with early motorcars without brakes, airbags, seatbelts or road rules? Modern cars remain capable of killing people, yet the answer has never been to abandon transport. We reduce risk through seatbelts, airbags, crash testing, speed limits, road engineering, driver licensing, drink-driving laws, child restraints, automatic braking, lane assist, better tyres and safer intersections.
Every one of those interventions accepts the same premise: people are going to travel, so make travelling safer. That is not moral surrender. It is practical responsibility.
The same principle governs aviation. Flying has never been risk-free, and aircraft still crash, yet society did not conclude that because planes could never be made perfectly safe, commercial aviation should be abandoned. Every accident became a source of learning. Design improved, pilot training improved, maintenance improved, air traffic control improved, navigation improved, weather forecasting improved, and emergency systems improved. The result was not zero risk; the result was extraordinary risk reduction.
Again, progress meant safer, not safe.
Medicine itself is built on the same philosophy. Few effective medical treatments are completely free of risk. Surgery involves risk, anaesthesia involves risk, prescription medicines involve risk, radiation therapy involves risk, chemotherapy involves risk, and vaccination can involve adverse events. The medical question is rarely, “Can this intervention cause harm?” The serious question is, “Do the expected benefits outweigh the risks compared with the available alternatives?”
Risk is contextual. That is why a drug that would never be justified for a healthy person may be completely justified for someone facing a serious illness. The comparison changes, the person changes, the circumstances change, and therefore the decision changes.
This is precisely why nicotine policy becomes distorted when every person and every product is treated as though they occupy the same starting point. A young person who has never smoked is not facing the same decision as a fifty-year-old who has smoked twenty cigarettes a day for thirty years. Their risk calculations are fundamentally different. For the non-smoker, starting nicotine use offers little obvious health benefit and introduces unnecessary dependence and exposure. For the long-term smoker, continuing to smoke is already a serious ongoing risk.
The relevant question for that person may be whether switching completely to a non-combustible nicotine product substantially reduces that existing risk. Those two situations cannot sensibly be collapsed into the same public-health message, yet that is often what happens.
We hear that vaping is not harmless, that nicotine is addictive, that some young people use nicotine and that long-term effects cannot be known with absolute certainty. All of those statements may be true, but none answers the central question facing the smoker: compared with smoking, what is the likely risk?
That is the question that matters.
A helmet is not harmless. It can be uncomfortable, restrict vision and, if poorly fitted, create problems. But if someone is about to ride a motorcycle, “helmets are not harmless” would be a bizarre public-health message. A seatbelt can cause injury in a crash, but nobody therefore concludes that passengers should remain unrestrained. Sunscreen is not a magical shield against every form of skin damage, but that does not mean we refuse to explain that it reduces risk. Condoms do not make sex completely risk-free, sterile injecting equipment does not make injecting drugs harmless, life jackets do not eliminate drowning risk, and smoke alarms do not prevent every fire death.
Yet we understand the principle: reducing harm matters, and sometimes reducing harm matters enormously.
This is where the word “safer” becomes more important than it first appears. “Safe” is absolute; “safer” is comparative. Safe asks whether a thing can cause harm, while safer asks whether it causes less harm than the realistic alternative.
Public policy often becomes confused when it substitutes the first question for the second.
Almost nothing in life is completely safe. Driving is not safe, eating is not safe, sport is not safe, medication is not safe, pregnancy is not safe, working is not safe, crossing a road is not safe, and even staying in bed indefinitely is not safe. The demand for perfect safety is therefore not really a safety standard. It is an impossibility standard, and applied selectively, it can become a barrier to improvement.
That is particularly dangerous when the existing product is as harmful as the cigarette.
If the incumbent technology were benign, extreme caution toward alternatives might make sense. But cigarettes are not benign, and that fact should dominate the comparison. The cigarette is already there. It is already legal, already familiar, already deeply entrenched and already used by millions.
So every regulation placed on an alternative exists within a market where the most dangerous product may remain available.
That creates a profound policy responsibility.
Suppose a smoker wants to stop smoking but has repeatedly failed using abstinence-based methods. They encounter vaping, a nicotine pouch, snus or another smoke-free alternative. What should society tell them?
Ideally, the answer would be truthful, nuanced and proportionate. The best outcome is to stop smoking. If you can stop using nicotine entirely, even better. But if you cannot or do not want to stop nicotine, switching completely away from combustible cigarettes can substantially change the risk you face.
That is information, not promotion, not endorsement and not industry propaganda. It is information, and adults should be capable of receiving it.
Yet in many places, public communication about nicotine has become strangely uncomfortable with comparative risk. Authorities may describe uncertainty in great detail while barely describing relative danger. Possible harms receive attention, reduced harms receive qualifiers, youth risks dominate discussion and adult smokers become an afterthought.
The result can be a public understanding in which cigarettes, vaping, nicotine pouches, heated tobacco and nicotine medicines all blur together into a general category called “nicotine products.”
From a toxicological perspective, that makes little sense. Method of delivery matters, dose matters, exposure matters and combustion matters enormously. The body does not respond to a political category called “tobacco and nicotine products.” It responds to chemicals, concentrations, particles, exposure pathways, frequency and duration.
This is why a risk continuum matters. It does not mean every product is good, every alternative deserves identical regulation, industry claims should be accepted uncritically, youth use should be ignored, or regulation should disappear. It means regulation should reflect differences in risk.
That principle should be uncontroversial. More dangerous products should face stronger controls, less dangerous products should face proportionately lower barriers, consumers should be told clearly where products sit relative to one another, innovation that reduces harm should be encouraged while risks are monitored and managed.
That is how we regulate almost everything else.
Strangely, tobacco policy sometimes appears to work in reverse.
In some systems, cigarettes can be bought from ordinary retailers while safer nicotine alternatives face greater hurdles. The product responsible for the overwhelming burden of tobacco-related disease may remain the easiest nicotine product to purchase.
That is historically extraordinary.
Imagine if, during the transition from open flames to electric lighting, society had made candles available in every supermarket but required special medical approval to purchase electric bulbs. Imagine if cars without seatbelts remained freely available while safer vehicles were heavily restricted because regulators could not guarantee they were completely risk-free. Imagine if authorities acknowledged that smoke alarms reduced fire deaths but worried that promoting them might “normalise living in houses.”
It would seem absurd, yet the structure of the argument is familiar. We become so focused on preventing any possible downside of the alternative that we lose sight of the far larger danger of the incumbent.
That is the risk of precaution without proportionality.
The precautionary principle sounds sensible: be cautious when uncertainty exists. But caution has two directions. There is the risk of adopting a new technology too quickly, and there is also the risk of delaying a safer technology while people continue using a much more dangerous one.
Both outcomes matter.
Doing nothing is still a decision. Restricting an alternative is still an intervention. Providing incomplete risk information still affects behaviour. Every policy has opportunity costs.
If a smoker is frightened away from vaping and continues smoking, that consequence belongs somewhere in the risk calculation. If regulations push consumers toward illicit markets, that belongs in the calculation. If high barriers discourage switching, that belongs in the calculation. If misinformation leads people to believe every nicotine product is equally dangerous, that belongs in the calculation.
Harm reduction demands that we count what happens in the real world, not simply what policy intended to happen.
That distinction, outcomes versus intentions, may be the most important lesson of all.
History is full of policies created for admirable reasons that produced unintended consequences. Prohibition did not eliminate alcohol demand, drug bans did not eliminate drug use, abstinence-only messaging did not eliminate sexual behaviour, and punitive responses to HIV-era drug use did not eliminate injecting.
People continued behaving like people.
Public health progressed when it accepted that reality.
Needle exchange was once controversial precisely because critics said it appeared to tolerate drug use. But the ethical question was not whether injecting drugs was desirable. It was whether people who were already injecting should also be exposed to HIV and hepatitis.
The answer became obvious.
You can disapprove of the behaviour while still reducing its consequences.
That is harm reduction.
You can want someone to quit smoking entirely while still helping them move to something less dangerous. Those beliefs are not contradictory. In fact, refusing the second because you prefer the first can become ethically difficult when the person continues to smoke.
Public health should meet people where they are, not only where we wish they were.
That principle sounds compassionate because it is, but it is also practical. Human beings are not laboratory variables. They have habits, dependencies, preferences, stress, social circumstances, past failures, routines, pleasures, fears and individual reasons for doing what they do. A policy that ignores those realities may look perfect on paper and fail in practice.
Harm reduction begins with humility. It says we may not be able to eliminate every risky behaviour immediately, but we can reduce the damage. That is not giving up. It is refusing to let perfection become the enemy of survival.
There is another important lesson hidden inside the history of safer: transitions are rarely tidy. The horse did not disappear the day the motorcar arrived, candles did not disappear when the first electric light was switched on, coal fires did not vanish when gas heating appeared, film cameras survived for decades after digital photography arrived, and landline telephones continued long after mobile phones became practical.
Old and new technologies coexist. Then consumer preferences, economics, regulation and technological improvement gradually shift the balance.
This matters because smoking will probably not end through a single dramatic prohibition. It may end through displacement. One smoker switches to vaping, another uses snus, another chooses nicotine pouches, another uses heated tobacco, another quits completely, another uses medication, and another combines approaches before eventually stopping cigarettes.
The pathway will not be uniform. Why should it be? People are different.
What matters is the direction of travel.
Away from combustion.
That should be the central public-health objective: not necessarily nicotine-free tomorrow, but smoke-free as quickly as possible.
The distinction matters because eliminating nicotine and eliminating smoking are not the same objective. They may overlap for some people, but insisting that they must always happen together can make the harder objective, eliminating smoke, unnecessarily difficult.
Imagine if we had treated every previous technological transition that way. We would have rejected cars. People still wanted transportation, rejected electricity because people still wanted artificial light, rejected central heating because people still wanted warmth and rejected safer medicines because people still became ill.
The human need was never the enemy.
The dangerous mechanism was.
And that brings us back to smoking.
What exactly are we trying to eliminate?
If the answer is premature death, cancer, cardiovascular disease, respiratory disease and the enormous burden created by inhaling cigarette smoke, then combustion should sit at the centre of policy.
Everything else follows from that.
Education should explain combustion, tax should reflect risk, regulation should reflect risk, product standards should reduce risk, communication should explain risk, consumers should understand risk and innovation should compete on reducing risk.
A system built around those principles could create powerful incentives. Cigarettes would become the least attractive option. Smoke-free alternatives would be easier to access than smoking, not harder. Products would have strong manufacturing standards, marketing to minors would be restricted, age verification would be serious, misleading claims would be punished, consumers would receive accurate information, research would continue, regulation would evolve as evidence improves, and smokers would be encouraged relentlessly to move down the risk continuum.
That is what rational harm reduction could look like.
It would not require loving nicotine, trusting tobacco companies, declaring vaping harmless, pretending there are no trade-offs or abandoning regulation. It would require only one thing: keeping the objective clear.
Fewer people inhaling smoke.
That is the outcome that matters.
One of the stranger objections to tobacco harm reduction is that some safer alternatives are manufactured by companies with terrible histories. The distrust is understandable. The tobacco industry deceived the public for decades, and that history should never be forgotten. Claims from tobacco companies should be scrutinised, evidence should be independently tested, and regulation should be strong.
But there is a danger in allowing distrust of the manufacturer to replace evaluation of the product.
A seatbelt does not become ineffective because a morally objectionable company manufactures it. A medicine does not become pharmacologically useless because its manufacturer has behaved badly in the past. The scientific question remains: what does the product do, what is the exposure, what is the risk and does it reduce harm compared with smoking?
Those questions must be answered by evidence, not by moral association.
Otherwise something peculiar happens.
The cigarette can become protected by our hatred of the cigarette manufacturer.
If a tobacco company earns more revenue from smoke-free products and less from cigarettes, that should at least raise an interesting question: what outcome do we actually want from the industry?
If the answer is fewer cigarettes, then commercial movement away from cigarettes is not inherently a public-health failure. It may be part of the mechanism by which cigarettes eventually disappear.
Markets can sometimes accelerate transitions faster than regulation alone.
This is not an argument for trusting corporations. It is an argument for aligning incentives. Make the safest products commercially attractive, make the most dangerous products less competitive, force companies to compete on reducing harm, regulate them aggressively, measure outcomes, reward movement away from combustion and punish misconduct.
That is more sophisticated than pretending we can freeze the nicotine market in place until dependence disappears.
Consumers are already changing it, technology is already changing it, and markets are already changing it. The only question is whether public policy helps steer that transition toward lower risk or tries to resist it.
History suggests resistance rarely stops technological change. It often changes where the change happens.
If legal markets cannot satisfy demand, illegal markets may. If regulated products disappear, unregulated products may replace them. If trusted information disappears, social media fills the gap. If governments refuse to acknowledge obvious differences in risk, consumers may stop trusting government communication altogether.
That loss of trust has consequences far beyond tobacco.
Public health depends on credibility, and credibility depends on telling people the whole truth, even when that truth is inconvenient.
That means acknowledging uncertainty, but it also means acknowledging relative risk.
It means being able to say two things at once: vaping is not risk-free, and smoking is much more dangerous; young people should not start using nicotine and adult smokers should not be misled about lower-risk alternatives; the best outcome is complete cessation and switching completely from cigarettes to a much lower-risk product can still be a major health improvement.
These statements do not conflict.
They become contradictory only in a culture that has forgotten how to think comparatively.
And perhaps that is the deeper issue.
Harm reduction is not really a debate about nicotine. It is a debate about how we understand progress.
Do we demand purity or improvement? Do we judge policies by intentions or outcomes? Do we evaluate technologies in isolation or against realistic alternatives? Do we treat adult behaviour as something to control or something to understand? Do we allow uncertainty to paralyse action or do we manage uncertainty while continuing to reduce known harm?
These questions appear everywhere: climate policy, drug policy, sexual health, road safety, alcohol, obesity, mental health, artificial intelligence, energy, medicine and environmental regulation.
Tobacco simply exposes the philosophical divide more clearly.
One worldview imagines that the safest society is one in which risky behaviour is eliminated. The other recognises that human beings will continue making imperfect choices and asks how to make those choices less dangerous.
History tends to favour the second approach, because civilisation itself is imperfect and progress has always been imperfect.
Every technological advance solves some problems and creates others. Electricity enabled modern society but created electrical hazards, cars transformed mobility but created road deaths and pollution, the internet connected humanity but created new forms of exploitation and misinformation, antibiotics saved millions but contributed to antimicrobial resistance, and agricultural technology prevented famine but created environmental consequences.
Nothing arrives without trade-offs.
Maturity lies not in pretending those trade-offs do not exist. It lies in comparing them intelligently.
That is why “safer” may be one of the most important words in public policy.
Safer accepts reality, allows progress, invites comparison, can be measured, can improve further and does not promise perfection.
It promises direction.
And direction matters when millions of lives are involved.
One day, historians may look back at cigarettes much as we look back at leaded petrol, asbestos insulation or open-flame lighting: something that once seemed ordinary, something embedded deeply in daily life, something later understood to carry enormous hidden costs and something eventually displaced by better technology.
If that happens, the end of smoking may not arrive through a single declaration. There may be no final “smoke-free day” and no moment when every smoker quits simultaneously. Instead, cigarettes may simply become obsolete, not because nicotine disappeared, but because burning tobacco stopped being the dominant way people consumed it.
That possibility should excite anyone whose true objective is reducing smoking-related disease.
Yet it also challenges deeply held ideas.
For some, the endgame has always meant a nicotine-free society. But perhaps history is offering another route.
Not prohibition.
Obsolescence.
That is how many dangerous technologies disappear. We do not always ban them. We build something better.
Nobody needed a global campaign to eradicate typewriters because computers displaced them. Nobody needed to criminalise horse-drawn transport because cars displaced it. Nobody had to arrest people for using candles because electricity displaced them. Nobody required an international treaty to abolish iceboxes because refrigerators displaced them.
Better technology changes behaviour, sometimes far more effectively than coercion.
Smoking may ultimately follow the same path, not because everyone suddenly decides nicotine is undesirable, but because lighting dried tobacco on fire becomes an increasingly irrational way of consuming it.
That is the transformation worth pursuing.
And it raises one final ethical question.
If we possess the ability to help smokers move from a highly dangerous technology to substantially less dangerous alternatives, what do we owe them?
We cannot owe them perfect products because we cannot provide those. We cannot owe them certainty about every possible effect fifty years into the future because science cannot provide that either.
But we can provide honesty.
We can explain what is known, explain what is uncertain, explain relative risk, regulate proportionately, protect young people without sacrificing adults, improve product standards, keep watching the evidence and, above all, remember who is carrying the greatest risk right now.
The person still smoking.
That person does not live in a theoretical future. Their exposure is occurring today. Every cigarette is combustion, every day matters and every year matters.
Public health must therefore compare not only risks, but time.
A hypothetical risk decades from now cannot automatically be treated as equivalent to a large, well-established risk occurring every day. Precaution should protect people from known dangers as well as unknown ones.
Sometimes the most dangerous decision is to wait for certainty while the old technology continues killing people.
The history of safer teaches us that progress rarely announces itself as perfection. It arrives looking incomplete, messy, controversial, sometimes commercially inconvenient, sometimes culturally unsettling and sometimes created by people or companies we dislike.
But eventually the comparison becomes impossible to ignore.
Stone became bronze, horses gave way to cars, candles gave way to electricity, open fires moved into stoves, letters gave way to telephones, typewriters gave way to computers, iceboxes gave way to refrigerators, lead paint gave way to safer coatings, unrestrained driving gave way to seatbelts and airbags, and unsafe injecting gave way to sterile equipment.
Smoking → ?
Perhaps that final arrow is not really a question of technology anymore.
The technology already exists.
The real question is whether our thinking is capable of making the same transition.
Because civilisation has never advanced by asking whether the next step was perfectly safe.
It advanced by asking whether it was safer than what came before, and then making it safer again.
That is how progress works.
That is how harm reduction works.
And that may ultimately be how smoking ends.




Harm reduction is ubiquitous. Harm reduction is about reducing the adverse consequences of risky behaviour when all efforts have been made to minimise that risk behaviour. Road safety policy is riddled with harm reduction. Obvious examples include car seat belts, airbags and motorcycle helmets. Bicycle helmets are also examples of harm reduction but here the benefits and adverse effects are closer together as harsh penalties for bicycle helmets seems to deter some from even riding a bike for a short distance. My colleagues and I started the first overt needle and syringe programme in Australia on 12 November 1986 at a time when there was a great deal of concern about HIV spreading beyond control among and then from people who inject drugs to the general community. We had to resort to civil disobedience as providing needle and syringes to people who inject drugs was illegal and governments were most reluctant to allow needle and syringe programs lest they be accused of abandoning drug prohibition. Harm reduction is pragmatic, compassionate, based on evidence, protective of human rights and values even incremental gains. Harm reduction recognises that most people struggling with serious problems resulting from their drug use are much more likely to improve with a multitude of tiny steps rather than a few heroic giant steps. Harm reduction accepts that many people even if they have serious drug problems want to keep using their preferred drug even though they are very worried about the consequences of using their drug of choice. Harm reduction allows them to reduce the consequences of their drug use. So people injecting heroin can continue to inject heroin when supplied with sterile injecting equipment but with a much reduced risk of blood borne viral infections including HIV and hepatitis B and C. People who are unable or unwilling to quit smoking but are worried about their risk of heart disease, cancer or COPD can switch to smoke-free nicotine products.
