In “Smoking, smoking cessation, and lung cancer in the UK since 1950: combination of national statistics with two case-control studies," they proclaim that "over the next few decades, a substantial decrease occurred in the United Kingdom in the prevalence of smoking… and, eventually, in lung cancer rates” (Peto et al., 2000, pp. 323). This proves that smoking has overall decreased in the UK. Many now understand the detrimental health impacts smoking can have on a person including lung cancer.
