Smoking Linked to Greater Loneliness After 65, Study Finds 2026

Smoking is linked to greater loneliness after age 65, according to a growing body of research that challenges the long-held myth of the social smoker. While cigarettes have long been associated with social breaks and camaraderie, recent evidence suggests the habit may actually isolate older adults.

The myth of the social smoker

For decades, smoking has been culturally tied to social interaction—the cigarette break at work, the huddle outside bars, the shared light. This image has painted smoking as a social activity that brings people together.

But science is now flipping that narrative. A recent study presented at a conference, drawing on data from 50,000 participants across 15 European countries, indicates that smoking is associated with greater loneliness, particularly after age 65.

What the new study found

The research, based on the SHARE project with a two-year follow-up, aimed to estimate the non-physical health effects of smoking. The preliminary results suggest that smoking harms not only our lungs but also our social relationships.

However, these findings are preliminary. As a conference abstract, essential details are still missing for a full independent evaluation, such as the study protocol, the exact definition of exposure, and the statistical model used.

Robust evidence from longitudinal research

Despite the preliminary nature of the conference findings, there is already strong evidence on this topic. A 2022 longitudinal study published in The Lancet provided significant proof with 8,780 English adults aged 50 and older, followed over 12 years.

Because it was a longitudinal cohort study and not a clinical trial, the researchers compared smokers and non-smokers over time, tracking changes in loneliness and social connection.

Why this matters for older adults

Loneliness is a growing public health concern among older adults, linked to poorer mental and physical health outcomes. If smoking contributes to social isolation, it adds another layer of risk for this population.

The findings also challenge the idea that smoking is a social glue. Instead, it may be a marker of social disadvantage or a cause of withdrawal from social activities due to health issues or stigma. The background to this story is set out in Health: latest articles.

Key takeaways

• Smoking is associated with increased loneliness in adults over 65, contradicting the social smoker myth.
• A large European study with 50,000 participants found a link, but results are preliminary.
• A 2022 Lancet study with 8,780 adults provided robust longitudinal evidence.
• Loneliness is a significant health risk for older adults, and smoking may exacerbate it.
• More research is needed to understand the causal mechanisms.

Comparing the evidence

What to watch next

As the conference study undergoes peer review, we can expect more detailed analyses. Future research should explore the mechanisms—whether smoking leads to social withdrawal, or if lonely individuals are more likely to smoke.

For now, the evidence suggests that quitting smoking could have social benefits for older adults, in addition to the well-known physical health benefits.
