TL;DR: Risks are not reduced by smoking cigarettes with lower machine-measured yields of tar and nicotine, but those who have only smoked pipes or cigars seem to have a lower risk for cardiovascular diseases.

TL;DR: In this paper, the authors measured age-, sex-, and race-specific risks of lung cancer incidence and mortality among never tobacco smokers among more than 940,000 adults who reported no history of smoking at enrollment in either of two large American Cancer Society Cancer Prevention Study cohorts during 1959-1972 and 1982-2000 (CPS-II).

TL;DR: Perception of advertising is higher among young smokers; market-share patterns across age and sex groups follow the perceived advertising patterns; and changes in market share resulting from advertising occur mainly in younger smokers.

TL;DR: The evidence as a whole supports the conclusion that, even in severe chronic obstructive pulmonary disease, smoking cessation slows the accelerated rate of lung function decline and improves survival compared with continued smoking.

TL;DR: This article summarizes principal findings from a conference convened by the American Cancer Society in June 1998 to examine the health risks of cigar smoking, finding that rates of cigarsmoking are rising among both adults and adolescents.
