Cigars carry real, well-documented health risks across nearly every organ system, including cancer, heart disease, and chronic lung damage. A large systematic review linked primary cigar smoking to elevated mortality from oral cancer, esophageal cancer, lung cancer, coronary heart disease, and aortic aneurysm, with risk climbing steeply based on how many cigars a person smokes per day and whether they inhale.1PubMed Central. Systematic review of cigar smoking and all cause and smoking related mortality The widespread belief that cigars are a safer alternative to cigarettes is rooted in a few grains of truth about how cigar smokers typically use the product, but the overall picture is far less reassuring than most casual smokers assume.
What Cigar Smoke Actually Contains
Cigar smoke is not a milder version of cigarette smoke. Because cigars use air-cured, fermented tobacco wrapped in leaf rather than paper, and because they lack the filters and ventilation holes built into modern cigarettes, the concentrations of several key toxicants are higher per gram of tobacco burned. The International Agency for Research on Cancer has noted that cigar smoke delivers substantially more nicotine, tar, carbon monoxide, and two potent carcinogens, benzo[a]pyrene and NNK, than cigarette smoke on a gram-for-gram basis.2British Journal of Cancer. The effect of cigar, cigarillo and pipe smoking on lung cancer risk and screening eligibility
The volatile organic compounds in cigar smoke tell a similar story. When researchers tested mainstream smoke from sixty domestic little cigar products under standardized conditions, the little cigars delivered substantially higher yields of volatile organic compounds than cigarettes, even after adjusting for the mass of tobacco in each product.3PubMed Central. Volatile Organic Compounds in Mainstream Smoke of Sixty Domestic Little Cigar Products In terms of secondhand exposure, cigars are also a larger problem indoors than cigarettes because a single cigar burns for much longer, producing a greater total volume of sidestream smoke. Research on volatile emissions from cigars found that they release levels of volatile organic compounds roughly ten to a hundred times higher than conventional cigarettes, along with aldehydes, phenols, and formaldehyde that concentrate in enclosed spaces.4CrossRef / E3S Web of Conferences.

Why “I Don’t Inhale” Doesn’t Mean What You Think
The single most common defense of cigar smoking is that you don’t inhale the smoke into your lungs the way cigarette smokers do. This is technically true for many traditional cigar smokers, but it leaves out two important details that reshape the risk picture entirely.
First, cigar smoke is alkaline, with a pH around 8.5, compared to the more acidic smoke of American cigarettes at roughly pH 5.3. At that higher pH, a much larger fraction of the nicotine exists in a form that passes readily through the lining of the mouth and throat without needing to reach the lungs at all.5Nature. Absorption of Nicotine in Cigarette and Cigar Smoke through the Oral Mucosa So even a cigar smoker who never draws smoke past the back of the throat absorbs meaningful amounts of nicotine, along with the carcinogens dissolved in that same smoke, directly through the tissues of the mouth. Research on small cigars confirmed that nicotine enters the body both through buccal absorption and through whatever degree of inhalation occurs.6PubMed. Absorption of nicotine from small cigars
Second, many cigar smokers do inhale, whether they realize it or not. A study measuring carbon monoxide and nicotine levels in ex-cigarette smokers who had switched to cigars found that their blood levels of carboxyhemoglobin and nicotine rose to levels comparable to what cigarette smokers experience, indicating deep inhalation. The researchers concluded that ex-cigarette smokers do not seem to lose their habit of inhaling when they switch to cigars, and that switching to cigars as a harm-reduction strategy would have little effect on their health.7PubMed Central. Effect of cigar smoking on carboxyhaemoglobin and plasma nicotine concentrations in primary pipe and cigar smokers and ex-cigarette smokers This is a particularly relevant finding because a large share of cigar users in the United States are former or current cigarette smokers, not lifelong cigar-only smokers.
Cancer Risks Across Multiple Sites
The cancer risk from cigars is not limited to the lungs. In fact, for smokers who do not inhale deeply, the cancers of the mouth, throat, esophagus, and larynx may pose the greatest danger, precisely because the smoke bathes those tissues directly. A systematic review of cigar smoking and mortality found that primary cigar smokers, meaning people who had never smoked cigarettes or pipes, had elevated mortality from oral cancer, esophageal cancer, laryngeal cancer, lung cancer, and pancreatic cancer. Strong dose-response trends by number of cigars per day and by inhalation level were observed for oral, esophageal, laryngeal, and lung cancers. Even among primary cigar smokers who reported no inhalation at all, risk was still highly elevated for oral, esophageal, and laryngeal cancers.1PubMed Central. Systematic review of cigar smoking and all cause and smoking related mortality
For lung cancer specifically, the risk depends heavily on how many cigars you smoke and whether you inhale. A case-control study found that among people who smoked only cigars or pipes, those consuming five to nine units per day had roughly three times the lung cancer risk of nonsmokers, and those smoking ten or more per day had nearly seven times the risk. Those who inhaled had about twelve times the risk.8PubMed. Lung cancer among cigar and pipe smokers A large European cohort study similarly confirmed that current smokers faced higher risks than former smokers and that inhalers faced higher risks than non-inhalers across multiple cancer types.9PubMed. Cigar and pipe smoking and cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC)
The takeaway here is that the number of cigars matters enormously. Someone who smokes one premium cigar at a weekend gathering and someone who smokes five cigarillos a day are in very different risk categories. But the non-inhalation defense only goes so far, especially for the cancers of the upper digestive and respiratory tract that develop from direct contact with smoke.
Heart Disease and Stroke
Cardiovascular harm from cigars tends to get less attention than cancer, but the evidence is substantial. A large multi-cohort analysis published in JAMA Network Open found that current cigar use was associated with a roughly 25% higher risk of stroke, a 32% higher risk of atrial fibrillation, and a 29% higher risk of heart failure compared to people who never smoked cigars. For exclusive cigar users who had never touched cigarettes, the stroke risk was even more pronounced, with about a 53% elevation.10JAMA Network Open. Cigar, Pipe, and Smokeless Tobacco Use and Cardiovascular Outcomes From Cross Cohort Collaboration
An earlier prospective study of U.S. men looked specifically at coronary heart disease deaths and found that the association was strongest among younger men. For men under 75 who were current cigar smokers, the adjusted rate of dying from coronary heart disease was about 30% higher than for nonsmokers. No increased risk was observed among current cigar smokers aged 75 or older, or among former cigar smokers of any age, suggesting that the heart risk fades after quitting and that it contributes most to premature death rather than late-life mortality.11PubMed. Cigar smoking and death from coronary heart disease in a prospective study of US men This mirrors what we see with cigarette smoking: the heart seems to recover meaningful function once exposure stops, making quitting genuinely beneficial even after years of use.
Lung Function and Respiratory Decline
Even among people who have never smoked a single cigarette, exclusive pipe or cigar use accelerated the decline of lung function over time. A pooled analysis from a large national cohort study found that among never-cigarette-smokers, those who had ever used pipes or cigars lost lung capacity faster than nonsmokers and faced about double the risk of COPD-related hospitalization or death. Their overall risk of dying from any cause was about 24% higher.12PubMed Central. Pipe and cigar use, lung function decline, and clinical outcomes: an analysis of the NHLBI Pooled Cohorts Study
Interestingly, a separate longitudinal study that looked specifically at diagnosed COPD found that exclusive cigar use, on its own, did not reach statistical significance for COPD risk in a fully adjusted model, while exclusive cigarette use and dual cigar-cigarette use did.13PubMed Central. Association between cigar use, with and without cigarettes, and incident diagnosed COPD: a longitudinal cohort study This doesn’t mean cigars are safe for the lungs. The pooled cohort data clearly shows accelerated lung function decline and worse outcomes. But it suggests that the clinical threshold for a formal COPD diagnosis may not be crossed as frequently with cigars alone, partly because many cigar-only users smoke less frequently than cigarette users and inhale less deeply. The lung damage is real; it may just progress more slowly in people who use cigars exclusively and in moderation.
What Cigars Do to Your Mouth
Because cigar smoke sits in the oral cavity for extended periods, the mouth takes a disproportionate hit. Data from a nationally representative sample found that current and former cigar or pipe smokers had significantly higher rates of moderate and severe periodontal disease than nonsmokers. The estimated prevalence of moderate to severe periodontitis among cigar and pipe smokers was about 18%, and on average, those smokers had four missing teeth. Smokers also showed more gum recession and more attachment loss, the structural deterioration that eventually loosens teeth.14PubMed. Cigar, pipe, and cigarette smoking as risk factors for periodontal disease and tooth loss
This is separate from the oral cancer risk discussed earlier. The periodontal damage alone, gum disease, receding gums, tooth loss, represents a quality-of-life cost that many cigar smokers don’t anticipate because they associate smoking-related harm with lungs and hearts, not with their dentist’s findings.
Does the Type of Cigar Matter
The cigar market in the United States spans a wide range: premium handmade cigars, mass-produced large cigars, cigarillos, and filtered little cigars that look almost indistinguishable from cigarettes. These are not equivalent products in terms of exposure or typical use patterns.
Biomarker data from U.S. adult tobacco users between 2013 and 2019 showed that exclusive premium cigar users were much less likely to be daily smokers than other cigar users. Their levels of toxic exposure biomarkers were comparable to those of non-premium large cigar users but generally lower than those of cigarillo smokers, filtered cigar smokers, and cigarette smokers. Even among daily users, premium cigar smokers had similar nicotine and tobacco-specific nitrosamine exposure but lower exposure to polycyclic aromatic hydrocarbons and volatile organic compounds compared to cigarillo and filtered cigar users.15PubMed Central. Biomarkers of Toxic Exposure and Oxidative Stress Among U.S. Adult Users of Premium Cigar Versus Other Cigar Subtypes: 2013-2019
The reasons for this gap are partly about the product and partly about behavior. Premium cigars are expensive, tend to be used occasionally and socially, and are typically not inhaled. Cigarillos and filtered little cigars are cheap, often flavored, frequently used daily, and more commonly inhaled. A filtered little cigar that costs a few cents and comes in a pack of twenty invites use patterns that look essentially identical to cigarette smoking. Cross-sectional data confirmed that even among cigar smokers who denied ever using cigarettes, cotinine levels (a marker of nicotine intake) were significantly elevated compared to never-smokers.16PubMed Central. The Association of Pipe and Cigar Use with Cotinine Levels, Lung Function and Airflow Obstruction: a Cross-sectional Study So while occasional premium cigar use produces measurably lower toxic exposure than daily cigarette or cigarillo smoking, it still pushes biomarkers above those of nonsmokers.
The Perception Gap
Cigar smokers are about three times as likely as non-cigar-smokers to believe that cigars are a safer alternative to cigarettes, and that perception has remained remarkably stable over time.17Tobacco Control. Trends in cigar smoking and perceptions of health risks among Massachusetts adults This belief is partly self-serving, the way anyone who enjoys something tends to downplay its costs, but it is also reinforced by the real differences in how people use cigars versus cigarettes. The occasional smoker who lights up once a month genuinely faces a different risk profile than a pack-a-day cigarette smoker. The mistake is in concluding that “different” means “safe.”
A systematic review of public perceptions found that some groups misperceive cigars and modified cigar products like blunts as less harmful than cigarettes, while survey data from the large national PATH Study showed that most U.S. adults actually perceived cigars as roughly equally harmful to cigarettes.18PubMed Central. Patterns of use, perceptions, and cardiopulmonary health risks of cigar products: a systematic review The perception gap is most pronounced among the people most at risk: young adults and current cigar users themselves. Among young adult cigar smokers, self-perception of addiction varied dramatically depending on the product. Those who primarily smoked cigarillos were most likely to identify themselves as addicted, while those who used cigar wraps mainly as a vehicle for cannabis were least likely to consider themselves addicted to cigars at all.19PubMed Central. Exploring the Experiences and Perceptions of Cigar Craving and Addiction among Young Adult Black Cigar Smokers
A Regulatory Blind Spot
Part of the reason cigar risks are underappreciated is that cigars have historically escaped the regulatory scrutiny applied to cigarettes. The landmark 1964 Surgeon General’s Report focused so heavily on cigarette health hazards that it inadvertently helped position cigars as a less-concerning product. Over subsequent decades, government regulators were slow to extend tobacco control measures to cigars even as cigar consumption rose. The 2009 Family Smoking Prevention and Tobacco Control Act gave the FDA jurisdiction over cigars, but health organizations have expressed frustration with the pace of actual regulation.20Pitt Journal of Environmental and Public Health Law. Regulators Throughout American History Have Been Reluctant To Regulate Cigars And The FDA Still Is Today, But Why?
This regulatory gap has practical consequences. Cigars are not required to carry the same graphic health warnings as cigarettes in many jurisdictions. Flavored cigarettes were banned in the United States in 2009, but flavored cigarillos remained widely available for years, attracting younger users with products that taste like grape, honey, or chocolate. The lack of regulatory parity sends an implicit signal that cigars are somehow different from cigarettes in a medically meaningful way, when the evidence says they are not.
The Financial Toll
The health consequences of cigar smoking add up at a population level. An analysis of U.S. healthcare expenditures attributable to cigar smoking between 2001 and 2018 estimated the annual cost at almost $30 billion. That burden fell disproportionately on third-party insurance programs, including a mix of public and private payers such as the Department of Veterans Affairs. The study also found evidence that health consequences associated with cigar smoking may persist after quitting, underscoring the importance of preventing initiation rather than relying entirely on cessation.21PLoS One. Annual U.S. healthcare expenditures attributable to cigar smoking between 2001 and 2018, overall and by payer
For the individual smoker, these numbers translate into a straightforward reality: cigar-related illness is not a theoretical abstraction. It generates doctor visits, hospitalizations, surgeries, and long-term care needs at rates high enough to move national spending figures. Whether you think of health costs in personal terms or societal ones, the bill is not trivial.
