Have tar and nicotine yields of cigarettes changed?

Have tar and nicotine yields of cigarettes changed?

L T Kozlowski et al. Science. .

Abstract

In official assays of the tar and nicotine yields of 12 popular brands of cigarettes, smoking machines took fewer puffs, on the average, in 1974 than in 1969. The decline in puffs appears to have been a major cause of the reported reductions in tar and nicotine yields during this period.
