Depending on how accurate and stable your device is, it can in fact extract much of the nicotine without releasing most of the compounds associated with combustion. As for TSCs, and benzene or other nasty things... I'm not sure, not to mention that you'd still be addicted to nicotine... not the nicest thing in the world. You'd still get most or all of the Polonium 210 there... eh. Tobacco in general, especially as it's grown and cured in modern times, is nasty nasty stuff.
Still, if you used something like the Volcano, or a medical volatilizer... you'd be in BETTER shape than smoking. For one, you don't have the intake of particulate from combustion, CO, and a certainly a measure of benzene and others PAHs, along with a lot of the tar. Do be careful however, often these devices have become associated with the use of marijuana, which, while I have no personal issue with that... has legal baggage varying on region. You don't want to be innocently using this for tobacco and have 'paraphernalia' issues arise.
