>E-cigs offer a better path to cessation through better control of the nicotine concentrations than cigs do, and e-cigs are probably one of the least harmful ways to get nicotine (and they're certainly cheaper than gum and patches).
Alternatively, e-cigs have made nicotine consumption cheaper, faster, more convenient, more socially acceptable, and available at much higher concentrations than tobacco. The aggregate being that nicotine addiction could very well increase overall, even if smoking rates drop. Most people don't realize that it's not really the smoke and lung cancer that leads to a majority of smoking deaths. It's the cardiovascular effects of nicotine leading to heart disease. Equating that to caffeine is ridiculous.
