(10,789 posts)here's a good review, more recent: http://www.medicalnewstoday.com/releases/50838.php
other more recent research questions that somewhat, but the general consensus is that nicotine alone is less harmful than cigarettes, so if you use patches, gum, or e-cigs to get your nicotine, you're better of than if you kept smoking.
I still think the harm of nicotine is such that it be regulated similar to alcohol and cigarettes, and that regulating nicotine use at the same relaxed level as cigarette use is reasonable. Expanding the opportunities for nicotine use (bringing it back into public places, restaurants, the workplace, schools and so forth) and addiction doesn't serve to reduce cigarette use, but only serves to make it easier (and potentially fashionable, again) to become addicted.
