Smoker now in my third decade with the habit(80's, 90's and now 00's, no I'm not old enough quite yet to have been smoking that long

). Forget all the talk about health issues, those are old and have been played to death, the economic one is the nasty short term problem-
Let's break it down for an average smoker, say a pack and a half to two packs a day. The average price of a pack is what, $3.50 nationwide with about $30.00 per carton being the norm(varies greatly depending on where you live)?
So you smoke a carton to a carton and a half a week, $30-$50 a week. Over the course of a month that is $120-$200(figuring for the max and a five/three paycheck month).
So, in terms of computer hardware you could buy a new CPU, upgrade your RAM, and buy a new video card
every three months for the cost of smoking. If you saved for six months, you could likely build up an entire system.
Of course you wouldn't want to jsut buy computer stuff. Say you go three months and purchase the CPU/RAM/Vid card and then had the next three months. How about a nice stereo system with Dolby Digital surround sound? Six months later you can go out and buy yourself a nice ~31" flat TV and new DVD player or pick up a very nice 21" monitor.
That is all just from the
cost of smoking, nothing else included. Look it over and then think of how much you purchase over the course of a decade, or how much you could invest over the course of a decade. If I had simply dropped all the money I have spent on smokes into MS stock from the time I started I would be a multi-millionaire(yes, I figured it out one day).
Forget talking about long term health problems which may very well not exist by the time you are old enough to be suffering with them, think about the cold hard cash that is honestly going up in smoke.
