Once again a study documents, smoking kills others

By Dr. Alan Kadish NMD

If your neighbors or spouse is smoking and you smell the results, they are literally putting you at risk for lung cancer. No longer will the arguments ” I smoke outside” going to cut it. There is a simple answer from a scientific point of view. Quit, period.

There are three types of tobacco smoke exposures. In the quoted study they refer to second hand smoke, your inhaling smoke as someone else smokes directly (first hand) and then there is the third hand smoke contact. It’s the stuff you see on the furniture and walls of a smokers environment. It’s the pervasive smell when you enter a smokers home or car or simply smell their clothing.

The materials from the oils and smoke of tobacco smoking deposited on your walls, and other surfaces are and remain carcinogens. I’m guessing that doesn’t sound like a preferable situation. And the chemicals are hard or impossible to remove, as simply painting over the surface is not adequately effective. To make maters worse the oils prevent proper adhesion of the paint so you need to clean the walls and ceilings with TSP, a cleaner) and then primer…. before painting…..not a small amount of work. If the point is not clear there are studies showing how even years later the chemicals will react with others in ones home and form additional contaminants.

Secondhand smoke at home raises lung cancer risk by up to 31%

  • Exposure to secondhand smoke (SHS) during adulthood can increase the risk of developing lung cancer in nonsmokers.

Study design

  • Systematic review and meta-analysis investigating the relationship between SHS and lung cancer that included 4 cohort and 5 case-control studies.
  • Funding: The study was supported by a Health Labour Sciences Research Grant of the Ministry of Health, Labour and Welfare of Japan.

Key results

  • Pooled relative risk for lung cancer associated with home SHS exposure: 1.28 (95% CI, 1.10-1.48) for both sexes; when analysis was limited to SHS exposure to women from men smoking (8 populations), pooled relative risk was 1.31 (95% CI, 1.12-1.54).
  • Pooled relative risk calculated from early publications (1984-1990; 1.30; 95% CI, 1.05-1.61) was higher compared with that from more recent publications (2001-2013; 1.25; 95% CI, 1.02-1.53).
  • The significant association remained even when potentially missing studies were included (pooled relative risk: 1.26; 95% CI. 1.09-1.46), and findings remained stable across subgroup analyses, including by those by study design, year of publication, and after adjusting for confounders.

Why this matters

  • The findings confirm that there is a significant association between SHS and lung cancer risk in nonsmoking adults who are exposed to SHS in their homes.
