In plain English

This item is a letter to the editor published in CMAJ in 2001. It was one of several letters debating a proposed ban on asbestos, and it reports no new research. The author, from the Department of Public Health Sciences at the University of Alberta, wrote that the data now seem to clearly refute certain old ideas about asbestos. These included the ideas that chrysotile does not cause lung cancer and that smoking and asbestos exposure do not really interact except among insulation workers. Citing the literature as a whole and studies of chrysotile-exposed workers, the author stated that a smoker exposed to asbestos is more than twice as likely to die of lung cancer as a smoker who was not exposed. The author wrote that workers' compensation boards had denied lung cancer claims from asbestos-exposed smokers for years. The author argued that if these workers' risk were compared with that of other smokers, not nonsmokers, many claims now denied would be accepted. The author concluded that the time has come for Canada to accept the inevitable global ban on exports of asbestos.

What the study did and found

• Design: Letter to the editor (correspondence); an opinion piece with no original data
• Who was studied: No population was studied. The letter was written by an author at the Department of Public Health Sciences, University of Alberta, Edmonton, in a 2001 CMAJ debate on banning asbestos.
• Exposure: Asbestos, including chrysotile, among workers, with attention to workers who also smoked
• Main results:
  • No original findings. The author stated that the data now seem to clearly refute old ideas, including that chrysotile does not cause lung cancer and that smoking and asbestos exposure do not really interact except among insulation workers.
  • The author stated, citing the totality of the literature and studies of chrysotile-exposed workers (not new data), that a smoker exposed to asbestos is more than twice as likely to die of lung cancer as a smoker not exposed to asbestos.
  • The author wrote that workers' compensation boards had denied lung cancer claims from asbestos-exposed smokers for years.
  • The author argued that an asbestos-exposed smoking worker's risk should be compared with that of other smokers, not nonsmokers, and that by that standard many claims now denied would be accepted.
• The authors' conclusion: The author concluded that the time has come for Canada to accept the inevitable global ban on exports of asbestos.
