If you think you're not as stupid because you smoke cigars rather than cigarettes, the National Cancer Institute says:

"Smoking only one to two cigars per day has significant health risks. For example, smoking one to two cigars per day doubles the risk for oral cancers and esophageal cancer compared to someone who has never smoked. And someone smoking at the same moderate level (one to two cigars daily) increases the risk of cancer of the larynx by more than six times that of a nonsmoker.

Like cigarette smoking, the risks from cigar smoking increase with the number of cigars smoked per day. Smoking three to four cigars per day increases the risk of oral cancers to 8.5 times greater than the risk of a nonsmoker, and smoking more than five cigars daily raises the oral cancer risk to 16 times the level for nonsmokers."

And that's just for people who don't inhale.
