If you're a smoker, think back to how much you've spent in the past year on tobacco. If that's not enough to make you stop then keep reading. The lifetime costs of smoking are enough to make you want to slap your forehead, wondering why you blew so much money for so long.

Wallethub just released a report on the real cost of smoking by each state, and Minnesota came in close to the top for the most costly state to be a smoker in.

An estimated 36.5 million people in the U.S. are smokers. Americans spend more than $300 billion, which includes both medical care and lost productivity. Wallethub calculated the potential monetary losses per person, including both the lifetime and annual cost of a cigarette pack per day, health care expenditures, income losses and other costs -- brought on by smoking and exposure to secondhand smoke.
