What is the most effective way to reduce tobacco use?

The World Health Organization is urging countries to follow six policies to prevent millions of deaths linked to tobacco use. The six policies are known as MPOWER, spelled M-P-O-W-E-R.
    The letter M means monitoring tobacco use and prevention policies. The P is for protecting people by establishing smoke-free areas. 0 is for offering services to help people stop smoking. The letter W means warning people about the dangers of tobacco. E is for enforcing bans on tobacco advertising and other forms of marketing. And R is for raising taxes on tobacco.
    (29)A World Health Organization report says raising taxes is the single most effective way to reduce tobacco use. A study found that governments now collect an average of five hundred times more money in tobacco taxes each year than they spend on control efforts.
    (30)The report says tobacco now causes more than five million deaths a year. It predicts this number will rise to more than eight million by the year two thousand thirty. By the end of the century, it says, tobacco could kill one billion people—ten times as many as in the twentieth century.
