Pipe and cigar smoking has long carried an image of refinement, even safety. Many people assume that smoking these products less frequently, or not inhaling fully, reduces the health risk. A major new study published in March 2026 challenges that assumption directly, and the findings are hard to ignore.

Researchers drew on data from more than 22,000 adults across multiple long-running US cohort studies. They found that pipe and cigar smoking links to significantly faster lung function decline, higher hospitalisation rates, and an increased risk of death. Crucially, these risks appeared even in people who had never smoked a single cigarette.

What Pipe and Cigar Smoking Does to Lung Function

The study, published in the journal Thorax, covered participants enrolled between 1971 and 2011 and tracked them through 2018. That gave researchers several decades of data on the long-term consequences of non-cigarette tobacco use.

Researchers assessed lung function through spirometry, a standard clinical test. It measures how much air a person can exhale and how fast. The two main markers were forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).

Both measures declined faster in exclusive pipe and cigar smokers than in people who had never used tobacco. The FEV1 to FVC ratio, a key indicator for detecting obstructive lung disease, also worsened over time. Small annual losses build up. Over years, they can tip someone into chronic lung disease.

Pipe and Cigar Smoking More Than Doubles COPD Risk

The study went beyond lung function and examined clinical outcomes. Exclusive pipe and cigar smokers faced more than double the risk of hospitalisation or death from chronic obstructive pulmonary disease (COPD) compared with non-tobacco users. They also carried a higher overall risk of death from any cause.

These outcomes held true in people with no cigarette history at all. That detail matters. It rules out the idea that prior cigarette use drove the results, and it places the evidence squarely on non-cigarette tobacco use.

COPD already ranks among the top causes of death worldwide. The World Health Organization reported that it affected more than 390 million people globally as of 2023. A tobacco product that speeds up its development demands serious attention from clinicians and the public alike.

Why These Findings Should Change Clinical Practice

Tobacco use in all its forms drives preventable illness. Public health campaigns have largely targeted cigarettes, leaving non-cigarette tobacco use in the background. This research makes a strong case for bringing it forward.

Clinicians should ask patients about all forms of tobacco, not cigarettes alone. Leaving pipe and cigar use off the checklist during a respiratory assessment risks missing a meaningful risk factor. These products belong in every tobacco-related health history.

The message for the public is just as direct. Switching to a pipe or cigars does not offer a safer exit from tobacco harm. The lungs accumulate damage regardless of the product’s reputation or how rarely someone uses it.

The Limits of the Evidence

The study design is observational. Researchers tracked associations rather than testing direct cause and effect. The findings do not definitively prove that pipe and cigar smoking caused the lung decline seen.

Even so, the consistency across decades of follow-up is notable. Effects appeared in never-cigarette smokers too, which adds weight to the association. The data come from US cohorts, so results may not map perfectly onto other populations. The biology of tobacco combustion, however, does not change by geography.

Time to Take Non-Cigarette Tobacco Use Seriously

Pipe and cigar smoking is not a low-risk habit. The evidence points to faster lung function loss and a more than twofold rise in COPD-related hospitalisation or death, even in those with no cigarette history.

Prevention and cessation efforts have too often focused only on cigarettes. That gap has real consequences for health. Studies like this one push the conversation in a more complete direction. All tobacco products carry risk. All of them deserve attention.
