I don't know, but I think cigar and pipe smoking are a perfectly valid way to get nicotine on your own terms while avoiding addiction. I have never seen someone cowering in the rain cradling a big cigar to get their fix.
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).
If you want a way to take in nicotine with lower risk of addiction, get an e-cig.
