And therein lies the rub -- I don't mind being addicted to nicotine any more than I mind being addicted to caffeine. To my current knowledge, they both seem relatively harmless, aside from the addiction, until and unless one tries to quit them, which causes withdrawals, and the cost is effectively negligible.

The main reason for quitting smoking had less to do with health concerns than cost, and not because the costs were unbearable, so much as that those costs were ridiculous. Ecigs have changed the equation, and so long as my nicotine budget stays lower than my caffeine budget, it's effectively negligible, however ignorant it might be.

As for the rest, you're completely right. It is a psychological problem. I'd need to see a good reason for quitting nicotine before my head can agree that there is one. I was worried about the costs rising, but they seem to be going the other way. I was worried about the health risks of nicotine, but indicators seem to be trending towards 'ecigs' are safe... and while I'm aware that the science could be wrong, incomplete, or even manipulated, I've gone from 'trying to quit' to 'meh, it's a harmless vice' mentally.
