IMHO the problem of quitting smoking is mostly a psychological one. If you can get your head on straight, the physical withdrawal symptoms are actually quite minimal.
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.
That's actually quite emboldening to hear. If you find the link, feel free to email me (contact info in profile) or post it here. I'd love to see it, but no pressure.
The flip side of that is that I'm in far better health than I was, and my respiratory system has rebounded to the point where I no longer wheeze going up a long flight of stairs, and it's of course far less expensive than cigarettes were.
There may prove to be downsides, but the recipes themselves aren't exactly complicated. If you pay attention to what you're getting, and buy from reputable vendors, you shouldn't have to worry about secret ingredients, or whether or not it's being cut with arsenic or anything.
If you're very worried about it, you can make your own liquid too.
