Cigar smoker here, and back when I had more time on my hands, I went through a pretty heavy cigar phase. Cigars are impractical as addictive agents, because they're very expensive and take a long time to consume. But they exhibit at least some mildly to moderately addictive properties. Back in grad school I found myself moving up the ladder from the occasional cigar a week, to the cigar every day, to the two to three cigars a day. I wouldn't say I needed them, or that the urge to smoke clawed at me every waking second. But I'd build my entire morning routine around the first cigar, my afternoon and evenings around the second and third, and so on. A day without a cigar left me pretty restless and unfocused. If that's not addiction, per se, it was something resembling dependence.

Cigarettes are more insidious tobacco delivery vehicles, but cigars aren't exactly health supplements.

Nicotine supplementation, absent the tobacco, is an interesting subject worth further study and consideration. On its own, given Gwern's and other research, it seems no more dangerous or addictive than caffeine (for example).
