Lottery is a type of gambling where people pay money to enter an event with an uncertain outcome. The odds of winning a prize are astronomically small, but lottery advertising carries the message that somebody, somewhere will win a fortune. This appeals to human nature, and people are willing to gamble a little in order to gain a lot. The brain responds to gambling in the same way that it reacts to drugs and alcohol: it releases dopamine, a neurotransmitter associated with feelings of pleasure.

Lotteries are a popular method of raising funds for public uses, and they have a long history in the United States. At the outset of the Revolutionary War, Benjamin Franklin organized a lottery to raise money for cannons to defend Philadelphia from the British. The Continental Congress used lotteries to finance the colonial military in the face of dwindling tax revenues.

Today, state-run lotteries enjoy broad public support. They are promoted as painless forms of taxes, and they often develop specific constituencies, such as convenience store operators; lottery suppliers (heavy contributions from these firms to state political campaigns are reported); teachers in those states that earmark lottery revenues for education; and legislators who quickly become accustomed to the additional income.

People who play the lottery should consider their own financial situation before making a decision to do so. A financial advisor can help them understand the tax implications of various options, and they should also consider whether to take a lump sum or annuity payments.
