Smoking's Social Image Meets Reality
For decades, smoking has carried a peculiar social mythology. Shared smoke breaks, the ritual offer of a cigarette, the clutch of colleagues huddled outside the office windows — these images have framed tobacco use as something that binds people together. But a large new European study presented this week at the European Respiratory Society (ERS) Congress in Barcelona, Spain, turns that picture on its head, suggesting that smoking does not merely accompany social isolation but may actively deepen it over time.
The research, which drew on data from more than 50,000 people across 15 countries, adds an important dimension to the public health conversation: smoking may contribute to loneliness, creating a cycle that erodes both physical and social well-being. The findings were presented by Dr. Keir Philip, clinical lecturer in respiratory medicine at the National Heart and Lung Institute, Imperial College London, UK.
Challenging the Social Smoker Narrative
Philip told the Congress that although the physical harms of smoking are well documented, far less attention has been paid to its social consequences. "Although we know smoking is bad for your physical health, we don't know what it does to our social health," he explained. Previous research has suggested that loneliness leads people to smoke, but Philip noted that very little research has examined the reverse relationship — whether smoking itself leads to greater loneliness. Part of the reason may be the persistent idea that smoking is a social activity.
"We regularly see people with smoking-related illnesses becoming increasingly socially isolated and lonely," Philip said, pointing to the clinical reality that smoking can slowly strip away the connections that make life feel full.
From England to Europe: Testing a Hypothesis
Philip and his collaborators had previously conducted a study in England that suggested smokers became lonelier over time than non-smokers. However, that single national dataset left open the possibility that the pattern was influenced by cultural factors, social norms, or attitudes toward smoking unique to the UK.
To investigate whether the relationship between smoking and loneliness held across different European settings, the researchers turned to the Survey of Health, Ageing and Retirement in Europe (SHARE), a large longitudinal dataset that tracks the health, social and economic circumstances of adults aged 50 and older. The sample included more than 50,000 people from 15 countries, offering a powerful lens on how smoking and loneliness interact across distinct national contexts.
A Rigorous Measure of Loneliness
Loneliness is not a single, simple feeling, so the study used the well-established UCLA loneliness scale. This instrument provides a loneliness score based on how often an individual feels they lack companionship, feel left out, and feel isolated from others — three core components that capture the experience of social disconnection.
The researchers compared current smokers with people who were not current smokers at the start of the study. They followed both groups for two years, using the same questionnaire at the beginning and again at the end. This longitudinal design allowed them to see not only whether smokers were lonelier, but whether their loneliness changed over time relative to non-smokers.
Key Findings: Smokers Are Lonelier and Growing More So
The study population was predominantly older adults — the average age of participants was 67. At the start of the research, 22 percent of participants were smokers, and nearly half (48.5 percent) had more than two chronic illnesses, a reminder that many participants were already facing multiple health challenges, which could themselves influence social participation.
The results were striking. Current smokers reported higher loneliness scores than non-smokers, even after the researchers accounted for other factors that might influence the results, such as age and gender. Moreover, people who currently smoked experienced larger increases in loneliness over the two-year follow-up period, even when the analysis controlled for their baseline loneliness levels.
This means that smoking was not merely correlated with loneliness at a single point in time; it was associated with a trajectory of deepening isolation.
A Consistent Pattern Across Europe
One of the most important aspects of the study is its geographic reach. The relationship between smoking and loneliness showed only slight variation between European regions, suggesting that the pattern is not a quirk of one country's culture, healthcare system, or social norms. Instead, it appears to reflect something more universal about the way smoking affects people's lives.
Philip emphasized that this consistency strengthens the case that the relationship is real. "We wanted to investigate if we saw the same relationship between smoking and loneliness across other countries too," he said. The answer, based on this dataset, is yes.
Why Smoking May Fuel Loneliness
The study does not prove a causal mechanism, and the researchers were careful not to overstate their findings. However, Philip offered a plausible explanation grounded in clinical practice: smokers who develop smoking-related illnesses often become increasingly socially isolated. These illnesses can limit mobility, reduce energy, and force people away from activities they once enjoyed, steadily cutting them off from friends, family, and community networks.
In addition, smoking itself may carry stigma in many societies, making smokers feel judged or unwelcome in social settings. Over time, these factors could compound, pushing people who smoke to the margins of social life.
Equally important is the potential for a vicious cycle. If loneliness leads people to smoke, and smoking in turn increases loneliness, then the two conditions may feed each other. This dynamic may be especially relevant for older adults, who already face higher risks of isolation due to retirement, bereavement, or declining health.
Implications for Public Health and Clinical Practice
If smoking contributes to loneliness, then tobacco control strategies may need to look beyond nicotine addiction alone. Philip's work suggests that helping smokers quit could also be a way to help them reconnect — but that may require additional social support, not just pharmacotherapy.
Public health campaigns that portray smoking as a solitary or isolating habit, rather than a social one, may resonate differently with different audiences. For healthcare professionals, the findings highlight the importance of asking older patients not just about their respiratory symptoms, but about their social connections and emotional well-being.
The study also contributes to a broader revival of interest in loneliness as a serious public health issue. Loneliness and social isolation are increasingly recognized as pressing concerns, particularly among older populations, and their relationship to behaviors like smoking has received relatively little research attention. This study represents a significant step in filling that gap.
Next Steps and Open Questions
While the size and cross-national reach of the study are notable, it was presented at a congress and has not yet been published in a peer-reviewed journal. Further research will be needed to confirm the findings and to explore the underlying mechanisms in greater detail.
Questions remain about whether the relationship differs by age, gender, or socioeconomic status; whether successful smoking cessation reverses the trend toward loneliness; and how cultural attitudes toward smoking shape the effects. Philip and his team hope that by demonstrating the link in diverse settings, they can inspire other researchers to investigate these questions.
"Although we know smoking is bad for your physical health, we don't know what it does to our social health," Philip said. This study begins to answer that question, but it also opens the door to a more holistic understanding of the harms of tobacco — one that goes beyond the lungs to the very fabric of social life.
