That depends on your usage patterns. Regular cigar smoking is associated with an increased risk for cancers of the lung, esophagus, larynx (voice box), and/or oral cavity (lip, tongue, mouth, throat). Cigar smoking is linked to gum disease and tooth loss. Heavy cigar smokers and those who inhale deeply may be at increased risk of developing coronary heart disease. Heavy cigar smoking also increases the risk for lung diseases, such as emphysema and chronic bronchitis.
