Smokingamong adults has hit the lowest level since 1941, but young people keep puffing away despite a decade of public service warnings aimed at teens, two new surveys by the federal Centers for Disease Control and Prevention conclude. Cigarette consumption by people over 18 is expected to hit 2,493 cigarettes this year, down from 2,539 in 1993, the CDC said. The other survey suggests 19 percent of high school seniors smoked daily in 1993 -- a number that's remained stable since 1984. The CDC released the figures to kick off the American Cancer Society's "Great American Smokeout."Post your opinion on theHealth & Medecinebulletin board.
