Here's something. A website where down at the bottom you can calculate how much money your spent on cigarettes over the years. I know the price has changed alot in 40 years. Today's price for a pack is about 8 bucks according to the prices I've seen in my local store. One pack a day costs the smoker almost 3,000 dollars a year. Yes, three grand.
