Using data from the 1979 and 1987 National Health Interview Survey (NH
IS), we test whether smokers alter their smoking habits in the face of
higher taxes. Smokers in high-tax states are more likely to smoke cig
arettes higher in tar and nicotine. Although tares reduce the number o
f cigarettes consumed per day among remaining smokers, total daily tar
and nicotine intake is unaffected. Young smokers, aged 18-24, are muc
h more responsive to changes in taxes than are older smokers, and thei
r total daily tar and nicotine intake actually increases after a tax h
ike. We illustrate that tax-induced compensating behavior may eliminat
e some health benefits generated by reduced smoking participation. A m
ore appropriate tax might be based on the tar and nicotine content of
cigarettes.
