From 1952 to 1956, Lorillard Tobacco Company’s Kent Micronite cigarettes were made with asbestos filters. The filters were advertised as increasing the experience and safety of smoking. However, smoking these cigarettes released crocidolite asbestos fibers into the lungs. This put individuals at risk for diseases such as pleural mesothelioma.


01. Asbestos Use in Cigarette Filters

Why Was Asbestos Used in Cigarette Filters?

From 1952 to at least mid-1956, Lorillard Tobacco Company’s Kent Micronite cigarettes contained asbestos fibers.

According to Lorillard, asbestos was included to provide a finer filtration system. The company advertised better filtration of smoke irritants and a pleasurable smoking experience.

Asbestos Cigarette Filters History at a Glance

  • Other Names: Kent Micronite Cigarettes, Micronite filters
  • Years of Manufacture: 1952 – 1956
  • Asbestos Use Banned: No
  • Associated Brands: Hollingsworth & Vose Company, H&V Specialties, Lorillard Tobacco Company

Lorillard Tobacco Company’s Kent Micronite cigarette brand contained crocidolite asbestos from 1952 to 1956. However, some records show the cigarettes were circulated past 1956.

During this time, records show consumers smoked about 13 billion Kent cigarettes.

Crocidolite asbestos was incorporated into the crepe-paper cigarette filters. Crocidolite, also called blue asbestos, is one of the rarest types of the mineral. It is also considered one of the most dangerous forms of asbestos due to the microscopic size of its fibers. Asbestos diseases associated with crocidolite asbestos exposure include:

Hollingsworth & Vose Company manufactured the filters under a subsidiary called H&V Specialties. The filters were attached to the rest of the cigarettes, packaged and sold by Lorillard Tobacco Company.

Advertisements claimed the filters protected consumer health by filtering out gas and tar. The company called the Micronite filters “the greatest health protection in cigarette history.”

“You can see the proof of Kent’s health protection! Exclusive “Micronite” filter removes 7 times more nicotine and tars than any other leading cigarette filter … you can see and taste the difference!”

– Kent Cigarette Ad, 1952

However, these claims of health protection were ironic. Cigarette smoking on its own is a risk factor for many diseases, including mesothelioma. The addition of asbestos to the cigarette filters compounded these health risks.

Lorillard officials may have been aware of the dangers before discontinuing the filters in 1956. An April 1954 memo from a research director to company president W.J. Halley said researchers had found “traces of mineral fiber” in the smoke.

Two months later, the president of Hollingsworth & Vose Company wrote of Lorillard officials’ worries about asbestos. “It is Lorillard’s belief that asbestos must be eliminated from the Kent cigarette as soon as possible because of a whispering campaign started by their competitors of the harmful effects of asbestos.”

Despite these anxieties, it was a year and a half before the company discontinued asbestos use in Kent Micronite cigarettes.

Dangers of Asbestos in Cigarette Filters

Asbestos exposure can lead to serious diseases, such as mesothelioma and lung cancer. This can occur when individuals inhale the fibers. Smokers of Kent Micronite cigarettes risked inhaling asbestos fibers each time they smoked.

Though any level of asbestos exposure can be dangerous, consistent and high levels of exposure can be much worse.

In 1995, researchers tested how much asbestos could be released by Kent Micronite cigarettes. The scientists obtained intact and unopened packs of the cigarettes manufactured from 1952 to 1956.

The researchers measured the total levels of asbestos per filter. They also analyzed how many fibers individuals would consume during a year of smoking. They found:

  • One filter contained approximately 10 mg of crocidolite asbestos.
  • Individuals smoking one pack each day would consume more than 131 million crocidolite fibers per year.

The study authors concluded individuals who smoked these cigarettes should be warned of “possible substantial exposure” to asbestos.

Consumers were not the only individuals at risk of asbestos exposure due to Kent cigarettes. One study examined the presence of cancers in a cohort of 33 asbestos filter workers. The researchers found an elevated incidence of cancer, including mesothelioma and lung cancer. They concluded the high rates of incidence and death among the workers could be attributed to heavy exposure to asbestos.

Asbestos-Related Diseases in Cohort of 33 Cigarette-Filter Workers

Total workers with cancer 19
Workers with lung cancer 11
Workers with malignant pleural mesothelioma 2
Workers with malignant peritoneal mesothelioma 3
Workers with asbestosis 3

The study authors noted the rate of cancer incidence was much higher than expected in a normal population. For example, the entire cohort of 33 workers was expected to only contain 3.5 cancer cases, as opposed to the actual 19. Many of these workers also died from their diseases. The researchers observed relative risk of death increased during subsequent follow-up periods. At the time of publication, 28 of the 33 workers had passed away, more than three times the expected number of deaths.

02. Cigarette Filters & Asbestos Exposure

Who Is at Risk of Asbestos Exposure From Cigarette Filters?

Asbestos-contaminated cigarettes may have exposed thousands of individuals to the dangerous mineral. This included consumers and employees involved in the manufacturing of the cigarettes.

Employees at Hollingsworth & Vose Company may have been exposed during the filter manufacturing process. The filters were manufactured using a “dry” process that produced large amounts of dust. Workers were present while asbestos fibers, cotton and acetate were mixed, carded and deposited onto crepe paper.

Individuals at Risk of Exposure From Asbestos Cigarette Filters

  • Hollingsworth & Vose Company employees (particularly those in West Groton or Rochdale, Massachusetts)
  • Kent cigarette smokers
  • Lorillard Tobacco Company factory employees (particularly those in Jersey City, New Jersey, or Louisville, Kentucky)

Any individual who consumed or worked around Kent Micronite cigarettes may have been exposed to asbestos. Secondhand smoke may also have contained asbestos fibers. Individuals who developed an asbestos disease from exposure to Kent Micronite cigarettes may be eligible for compensation.

03. Asbestos Lawsuits

Asbestos Lawsuits, Settlements & Other Compensation

Victims of exposure to asbestos-filtered cigarettes may be eligible for mesothelioma compensation. For instance, victims may be eligible to file asbestos lawsuits. Successful lawsuits prove negligence on the part of the asbestos company and result in awards for the plaintiffs.

Mesothelioma victims wishing to file a lawsuit against Lorillard, Hollingsworth & Vose Company or any other asbestos company should contact a mesothelioma attorney.

Although the company used asbestos for a short time, it is still named in cases today. Lorillard was purchased by Reynolds American, Inc. in 2014. Reynolds American, Inc. inherited the liability associated with Lorillard’s asbestos use. Recent financial statements showed the company was a defendant in 48 asbestos filter cases as of 2020.

Since January 2018, Reynolds American, Inc. has paid or agreed to pay more than $31 million to settle Kent Micronite filter lawsuits. In previous financial reports, the company reported paying more than $42 million to settle asbestos lawsuits between 2014 and 2017.

Compensation Following Asbestos Exposure From Cigarette Filters

Notable verdicts involving Kent cigarettes include:

  • In July 2014, a Los Angeles jury decided a $17.7 million verdict in favor of the wife of an asbestos victim. The man smoked Kent cigarettes and died in 1998 from associated lung cancer. The unanimous decision assigned 17% liability to Lorillard, 50% to the victim himself and 33% to other manufacturers. Lorillard’s portion of the total award amounted to about $3 million.
  • In May 2000, a San Francisco jury awarded the family of an asbestos victim $1.04 million. The woman smoked for much of her life, exclusively using Kent cigarettes between 1953 and 1979. As a result, in 1996, the woman was diagnosed with malignant abdominal mesothelioma. She died shortly after, and her two children filed a lawsuit against Lorillard. The jury decided the case in favor of the victim’s children.
