Smoking does cause lung cancer. It also causes esophageal cancer, stomach cancer, mouth cancer, bladder cancer, cardiovascular disease, worsening of Graves orbitopathy, worsening of IBD symptoms, COPD, and much, much more.

Smoking companies have fought a long, hard battle and paid billions of dollars to lobbyists to trivialize smoking. Now other harmful companies employ similar tactics, like pharma companies.

One of their most successful methods in getting women to smoke was using psychology to trick women into thinking smoking symbolizes freedom. They paid Sigmund Freud's nephew for that particular stunt btw.

Libertarians pick the most retarded hills to die on. You should not be defending cigarette companies, ffs.
