I have found interesting application QuitCount.
What is QuitCount?
QuitCount is a simple counter that shows what you saved since you quit smoking. Once you tell it the date you quit, how much you smoked, and how much it cost, it'll tell you how many cigarettes you didn't smoke since, and how much it makes in terms of money, tar, and life expectancy. It is released under the terms of the GPL, version 3 or later.
I think to create Custom SQL Report that will show the same info as QuitCount.
