Cigarette breaks are a great -feeling way to punctuate your day because they force you to step outside for a brief moment once in a while with only your thoughts, and so they easily become tremendously habit-forming.

The good thing about cigars is that they're terribly inconvenient. They're harder to acquire, harder to store properly, harder carry around, and they take nearly 10x as long to smoke. I've smoked a few cigars per year for almost 2 decades, and I can't imagine doing the same with cigarettes. Nobody really buys and smokes an entire pack of cigarettes in one night every few months (because it would be insane), but if they did, it's unlikely they'd become addicted.
