     Few laws are so effective that you can see results just days after they take effect. But in the nine days

since the federal cigarette tax more than doubled-to $1.01 per pack-smokers have jammed telephone "quit

lines" across the country seeking to kick the habit.

     This is not a surprise to public health advocates. They've studied the effect of state tax increases for

years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which

fiercely fights every tax increase.

     The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve

public health, health, they raise money and most particularly, they deter people from taking up the habit as

teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.

     In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost

$10.06 at one drugstore Wednesday. Charleston, S.C., where the 7-cent-a-pack tax is the lowest in the

nation. The price was $4.78.

     The influence is obvious.

     In New York, high school smoking hit a new low in the latest surveys-13.8%, far below the national

average. By comparison, 26% of high school students smoke in Kentucky, Other low-tax states have similarly

depressing teen-smoking records.

     Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the

burden of the tax falls on low-income Americans "who choose to smoke."

     That's true, But there is more reason in keeping future generations of low-income workers from getting

hooked in the first place, As for today's adults, if the new tax drives them to quit, they will have more to

spend on their families, cut their risk of cancer and heart disease and feel better.
