Teenage cigarette smoking is sensitive to the price of cigarettes. The most recent research suggests that a 10% increase in price would reduce the number of teenagers who smoke by 7%. If the proposed 43-cent hike in the Federal excise tax rate on cigarettes contained in the Hatch-Kennedy Bill were enacted, the number of teenage smokers would fall by approximately 16%. This translates into more than 2.6 million fewer smokers and more than 850,000 fewer smoking-related premature deaths in the current cohort of 0 to 17-year-olds. Adjusted for inflation, the current 24-cent-a-pack tax costs the buyer about half of the original cigarette tax of 8 cents imposed in 1951. A substantial tax hike would curb youth smoking; this strategy should move to the forefront of the antismoking campaign.
