Tobacco products are estimated to cause approximately 90% of lung cancer cases. Some of the thinking is that the nicotine in cigarettes may paralyze the cilia which are the little brushes on the lungs that help bring things up and help you to expectorate them. The cilia beat in unison, and sweep the mucus upwards, towards the back of the throat. American Journal of Public Health. Statistically significant reductions in levels of urinary metabolites of a tobacco-specific lung carcinogen were achieved by reduction in smoking, but for most smokers, reductions were modest and transient.

And because of its carcinogenic effects, the commercial production of this chemical stopped in the United States in the 1950s. So nicotine and all that junk are just sticking and staying down there, whereas THC probably doesn’t do that. The mucus is normally swept out of the lungs by the cilia on the epithelial cells lining the trachea, bronchi and bronchioles . Many studies have demonstrated the co-carcinogenic effects of catechol, which is an important constituent of cigarette smoke. For each ciliated cell in the body, there are between 100 and 200 cilia, each one anchored by another organelle known as the basal body. Tobacco as a habit can cause irreversible damage. The most common reason to suffer damaged or paralyzed cilia, however, is smoking. Tobacco products are estimated to cause approximately 90% of lung cancer cases.
