There are some risks in terms of your mouth/lips. Cigars are a lot less harmful because it's customary not to inhale them, you can obviously but the vast majority of cigar smokers don't. They also appear to be far less addictive than cigarettes, personally I would say they aren't addictive at all, during the winter in the UK I don't smoke any for 3-4 months, during the summer I only smoke a couple a week.
