Smoking alone or in combination with asbestos exposure doesn't increase the risk of developing mesothelioma. But the risk of lung cancer multiplies significantly among those exposed to asbestos and cigarette smoke. Both smoking and asbestos can cause lung cancer.
Written by Michelle Whitmer | Scientifically Reviewed By Yvonne Waterman | Edited By Walter Pacheco | Last Update: June 28, 2024
Smoking is the leading cause of preventable death in the U.S., and asbestos exposure is the No. 1 cause of occupational deaths worldwide. Exposure to both can have detrimental effects on respiratory health and cancer risk.
The combination of smoking and asbestos exposure greatly increases a person’s risk of developing lung cancer. It also may accelerate the onset of asbestosis and increase the severity of symptoms. Smoking affects the development and severity of asbestos-related diseases in several ways.
Smoking does not increase the risk of mesothelioma among people exposed to asbestos. Scientists do not know why this is true. They understand more about the increased risk of lung cancer. They believe it relates to the combined effects of smoking and asbestos.
Studies have estimated that between 50% and 80% of asbestos workers are smokers. This factor helps explain why asbestos-related lung cancer cases outnumber mesothelioma cases.
Many people may not realize asbestos causes lung cancer in addition to mesothelioma. As asbestos enters the lungs, it can damage the tissue within the lungs and the air sacs that help exchange air between your bloodstream and the outside air.
Smoking has not been directly linked to mesothelioma. The primary cause of malignant mesothelioma is asbestos exposure. However, smoking is a risk factor for developing asbestos-related lung cancer. If asbestos exposure has occurred, you may have an increased risk of developing mesothelioma.
It was the most depressing appointment of my life. I could have guessed maybe lung cancer because I had been a smoker. But mesothelioma? No. A cancer caused by asbestos exposure wasn’t even on my radar.
Decades of research have not found an increased risk of mesothelioma among asbestos workers who smoke. Only one study from 2002 found a common gene mutation among a group of smokers with mesothelioma. A 2013 study looking deeper into the topic found no relationship.
Smoking does worsen the pulmonary symptoms of mesothelioma and reduces your body’s overall ability to heal. Doctors advise all patients with cancer or respiratory illnesses to avoid tobacco smoke.

Start NowThe Centers for Disease Control and Prevention says smoking is the cause of 80% to 90% of lung cancer cases. Asbestos exposure is the primary cause in only about 4% of cases.
Any amount of asbestos exposure contributes to the incidence of lung cancer, even in heavy smokers. This data is according to a 2020 study published in Environmental Research and Public Health.
Both smoking and asbestos exposure can independently cause lung cancer. The risks multiply when combined. Decades of studies have shown varying degrees of multiplicative risk. This is likely affected by the exposure levels among the participants.
A 2013 study involving more than 50,000 medical records from insulation workers revealed how occupational asbestos exposure and smoking have a synergistic effect on lung cancer death rates.
Occupational asbestos exposure on its own was associated with a lung cancer death rate five times higher than average. When asbestos exposure was combined with smoking, the death rate was 28 times higher than average. Among those who also developed asbestosis, the death rate was 36.8 times higher.

The study also showed quitting smoking gradually reduces a person’s risk of lung cancer. The hazards caused by asbestos exposure are irreversible.
Smoking increases the risk of asbestosis among those exposed to asbestos. Research by the Agency for Toxic Substances and Disease Registry shows this risk.
Asbestosis is a chronic pulmonary disease in which the lungs undergo slow and repetitive scarring, or fibrosis. There is no known cure. The inhalation of asbestos fibers causes asbestosis. It is most prevalent among workers with long and heavy exposure to asbestos.
A 1995 study concluded smokers have increased rates of asbestosis progression. An earlier report showed approximately 12% of asbestosis patients might develop lung cancer. Asbestos-exposed smokers with asbestosis have a significantly increased risk of lung cancer.
The effect of smoking on asbestosis has been a point of debate among researchers. Some experts believe smoking contributes to asbestosis and others challenge this notion. Significant evidence shows how much smoking can worsen symptoms of asbestosis, including breathlessness.
In the U.S., one tobacco product is known to have been manufactured with asbestos as an ingredient: Kent Micronite filtered cigarettes. From 1952 to 1956, H&V Specialties manufactured cigarette filters for the Lorillard Tobacco Company using a type of asbestos called crocidolite.
Lorillard marketed Kent Micronites as the safest cigarettes ever invented, claiming the design was inspired by high-tech industrial filtration technology. Unfortunately, crocidolite is now widely considered the most toxic form of asbestos.
Although crocidolite was used in certain specialized filters, the crimped crepe paper of the Micronite cigarette filter did not prevent consumers from inhaling microscopic crocidolite fibers when they smoked Kent cigarettes. One study found a smoker could inhale “an average of 170,000 crocidolite airborne structures” from only two puffs on a Kent Micronite.
In general, cigarette filters do not make cigarettes significantly safer. The filters typically only trap the largest tar particles, allowing most of the toxic substances in cigarettes to pass through. The Kent Micronite filter made smoking more dangerous by adding asbestos to the list of cancer-causing substances smokers were exposed to.
