Every time you try to picture what daily American life looked like sixty or seventy years ago, it’s easy to land on the rose-tinted version: backyard barbecues, drive-in movies, families piled into station wagons headed for the lake. What that picture tends to leave out is the part where the doctor lit a cigarette in the examination room, the kids were rolling around loose in the back of that station wagon with no seatbelt in sight, and the toddler at home had just been quieted with a spoonful of syrup that contained morphine.
This isn’t a list designed to make you feel smug about living in 2026. Most of what follows wasn’t done out of ignorance or recklessness in the way we’d understand those words today. It was simply the norm – the completely unremarkable, socially accepted, often government-endorsed norm. That’s what makes it so strange to look back at. Nobody was hiding these things. They were advertised, prescribed, celebrated, and in some cases actively recommended by the people whose job it was to keep Americans healthy.
Six of those habits, in particular, stand out. Not because they were fringe behaviors practiced by a handful of outliers, but because they were things ordinary Americans did without a second thought – things that would cause genuine alarm today.
1. Smoking Everywhere – Including the Hospital Ward
In 1964, according to the National Institutes of Health, 40% of Americans were regular smokers, with the majority of men (53%) and about one-third of women lighting up regularly. That number is striking on its own. But the more revealing detail isn’t the count, it’s the location. People smoked at home, in restaurants, in bars, on trains and airplanes, in automobiles, in public buildings – and in hospitals.
That last one tends to stop people. From the late 1800s until the early 1990s, tobacco was a routine part of the American hospital. As Working Nurse documents, doctors might smoke cigars or pipes while delivering a diagnosis or even while in the operating room. Nurses routinely smoked at the nurses’ station, during report, while organizing their med carts, and sometimes alongside their patients. Some hospitals had designated smoking lounges right next to patient rooms. Hospitals sometimes sold their patients cigarettes, which were taken into patient rooms on carts alongside chewing gum, toiletries, and books.
The cultural saturation went deep. Movie stars smoked on screen and off – John Wayne and Ronald Reagan both had endorsement deals with tobacco companies. Cartoon characters smoked on their shows and in cigarette commercials, most notably Fred and Wilma Flintstone. Even after Congress banned smoking on airlines in 1988 and after many major cities passed clean indoor air laws, few hospitals discouraged patients, visitors, medical personnel, or other employees from smoking. It took until 1992 for the Joint Commission on Accreditation of Healthcare Organizations to mandate that hospitals be smoke-free by December 31, 1993, with more than 96% of US hospitals ultimately complying with the new standard.
The shift, when it finally came, was seismic. Today, smoking rates in the US sit around 12% of adults. The hospital ward where nurses once kept a full ashtray on their med cart is now a campus where you often can’t light up within 30 feet of the entrance.
2. Letting Children Ride Completely Unrestrained in Cars
Typically, children rode in parents’ laps, or on their own in back seats without any safety protections. That was simply how it was done, for most of the history of the automobile in America. The idea that a child needed to be secured in anything – let alone a purpose-built safety seat with a five-point harness – didn’t become federal law until 1978, and it took another seven years after that for all 50 states to follow through.
For much of the 20th century, kids rode in cars unrestrained or in seats designed more for parents’ convenience than children’s safety. Nobody seemed particularly concerned. Even after child safety seats became available in the late 1960s, few parents used them – or they used them incorrectly. The early “seats” sold before that era weren’t safety devices at all. They were simply to help parents keep a better eye on their children during a time when it was normal for kids to climb around the vehicle freely. They also helped give the kids a better view out the windshield.
The pediatrician who arguably changed this the most was Dr. Robert Sanders of Tennessee. Working throughout Tennessee during the mid-1970s, he heard arguments that babies belonged in their mother’s arms, that kids had a right to sit in truck beds, and that parenting choices were a matter of personal liberties. Only a small fraction of families in the US had or used a child car seat, and state legislatures were hesitant to require it. He persisted anyway. In 1978, Tennessee passed the first true car seat law, stating that young children had to ride in a child safety seat that met federal safety standards. By 1985, all 50 states had similar laws.
A 2026 report from TIME captures just how much that shift mattered. In 1975, more than 3,600 children under 13 years old died in crashes. By 2017, that figure dropped to 939. The math there isn’t subtle.
3. Pumping Leaded Gasoline Into Every Car on the Road
On December 9, 1921, a mechanical engineer named Thomas Midgley Jr., working at General Motors’ research division in Dayton, Ohio, discovered that tetraethyl lead could be added to gasoline to stop engine knocking. The chemical worked. Engines ran more smoothly. And for the next seven decades, it was pumped into virtually every car in America without meaningful public debate.
Between the 1920s and the mid-1990s, an estimated 7 million tons of lead were burned in American gasoline alone. That lead didn’t disappear. It settled into soil near roadways, drifted into water supplies, and was inhaled by billions of people worldwide. The consequences, we now know, were staggering. Researchers have since linked the leaded gasoline era to measurable drops in population-wide IQ scores, increased rates of violent crime, and widespread cardiovascular damage in exposed generations.
A 2024 study from Duke University put numbers on the mental health dimension specifically. Exposure to car exhaust from leaded gas during childhood altered the balance of mental health in the US population, making generations of Americans more depressed, anxious, and inattentive or hyperactive. The research estimates that 151 million cases of psychiatric disorder over the past 75 years resulted from American children’s exposure to lead. One hundred and fifty-one million. That’s not a rounding error – that’s a public health catastrophe that unfolded one gas station fill-up at a time.
Leaded gasoline was finally banned in the US in 1996. The people who fought hardest for its continued use were, unsurprisingly, the corporations that profited from it. The people who paid the price were largely children who had no idea what was coming out of the tailpipe.
4. Children Chasing DDT Fog Trucks Through the Neighborhood
If you grew up in suburban America in the 1950s or early 1960s, you probably know this one already. DDT was sprayed widely through American towns as pest control throughout those decades. Running behind the fogger was a popular pastime for suburban children. Kids on bikes, kids on foot, kids in swimsuits on a warm evening – all of them chasing a slow-moving truck billowing thick chemical clouds meant to kill mosquitoes.
Photographs from the late 1940s and 1950s show American housewives drenching their kitchens with DDT and children playing in the chemical fog from municipal spray trucks. Newspaper articles and advertisements called DDT “magic” and a “miracle.” Government health posters promoted the pesticide’s safety, and public demonstrations were staged to show there was no danger to children. Even at the time, some kids noticed that the men doing the spraying wore protective suits.
The cognitive dissonance of that image – men in full protective gear pumping chemical fog while children ran laughing through it – captures something essential about how the era handled risk. DDT was enormously effective at killing insects, including the mosquitoes responsible for diseases like malaria. That effectiveness was real. But research focusing on women’s age at exposure found that those exposed to the pesticide before puberty showed significantly elevated breast cancer risk in later life. The timing of exposure, researchers now understand, matters enormously – what enters the body before breast development can affect breast tissue in ways that only show up decades later.
DDT was banned in 1972. By the mid-1960s, there was growing criticism as evidence mounted of its damaging impact on the environment, and concern that it could be a human carcinogen. Researchers had determined that DDT was causing many birds to lay eggs with abnormally thin, fragile shells. The summer ritual of chasing the fog truck – something many older Americans remember with nostalgia – turns out to have been a long-running uncontrolled experiment, and the children were the test subjects.
5. Buying Heroin, Cocaine, and Morphine at the Drugstore
During the 19th and early 20th centuries, cure-all medicines were popular and accessible to everyone. With no restrictions in place, many medicines were made with dangerous ingredients such as alcohol, cocaine, morphine, opium, and chloroform. Children and babies were given these medications, and death was often an unfortunate side effect.
The Smithsonian’s reporting on the first opioid epidemic makes clear how openly all of this was sold. Products like heroin cough drops and cocaine-laced toothache medicine were sold freely over the counter, backed by colorful advertising. An 1885 print ad for Mrs. Winslow’s Soothing Syrup for Teething Children showed a mother and her two children looking suspiciously beatific. The morphine content may have helped.
Then there was Bayer. Yes, the same company that makes the aspirin in your medicine cabinet. Bayer began advertising a heroin-laced cough medicine in 1898, marketed toward children suffering from sore throats, coughs, and colds. Some bottles depicted children eagerly reaching for the medicine, with moms giving their sick kids heroin on a spoon. Doctors started to suspect that heroin might not be as non-addictive as it seemed when patients began coming back for bottle after bottle. Despite pushback from physicians and mounting negative stories about heroin’s side effects, Bayer continued to market and produce the product until 1913.
In American history, misguided medicine ran rampant, especially before the 1906 Food and Drugs Act – the first major consumer protection law to crack down on misleading food and drug labels – and the formation of the Food and Drug Administration in the 1930s. Before those guardrails existed, the drugstore shelf was essentially a free-for-all. The same product that calmed a teething baby might cause a fatal overdose in a slightly larger dose. Parents had no way to know. The label often didn’t say.
6. Doctors Endorsing Cigarette Brands in Medical Advertisements
Separate from the general smoking culture – though obviously related to it – there was a specific, extraordinary chapter in which American physicians were recruited as marketing tools for the tobacco industry. This wasn’t doctors staying silent about risks. This was doctors actively selling the product.
Historical archives are full of photographs of notable figures with a cigarette in hand, and physicians were particularly prized as endorsers. Tobacco companies advertised in newspapers and magazines, on billboards, and on radio and television. They distributed baseball cards in cigarette packs and sponsored sporting events. Their mission was to convince Americans that smoking made smokers look sophisticated and cool. Getting a doctor’s face into an ad was simply the prestige tier of that strategy.
One of the most famous campaigns ran for Camel cigarettes, featuring the tagline “More doctors smoke Camels than any other cigarette” – a claim based on surveys the company itself commissioned and distributed to physicians with free cartons of cigarettes. The American Medical Association, for its part, didn’t stop accepting tobacco advertising in its journal until January 1954, and even then the move was framed as a response to the medical claims increasingly appearing in cigarette ads, not as an acknowledgment that smoking was harmful.
When the 1964 Surgeon General’s report finally landed, the committee found that smokers experienced a 70% increase in mortality and a nine- to ten-fold greater risk of developing lung cancer compared to nonsmokers. The doctors who’d been smiling from cigarette ads in waiting room magazines didn’t cause that damage alone – but they lent the habit a credibility that made it harder to undo for decades.
How Far We’ve Actually Come
It would be easy to read all of this as an extended exercise in feeling superior to previous generations. That’s not quite the right response. Most of the people who ran behind DDT trucks, smoked in maternity wards, or spooned morphine syrup into a crying baby weren’t monsters or idiots. They were operating inside systems that told them these things were safe, normal, or even beneficial – and those systems were often backed by corporations with strong financial incentives to keep it that way.
What the list above actually illustrates is how long it can take for harm to become visible when powerful interests are invested in keeping it invisible. Lead in gasoline had critics from its earliest days, but it took seventy years and a generation of measurably lowered IQ scores to get it banned. Heroin in cough medicine was sold for fifteen years after doctors started noticing that patients couldn’t stop asking for it. DDT was sprayed directly onto children while the men applying it wore protective equipment. The knowledge, in many cases, existed. The question was always whether it was allowed to matter.
The habits of 2026 that will look just as alarming to people in 2080 probably exist already. We just haven’t gotten there yet.
