For example, use of cigarettes in the past 30 days as reported in 2007 was 7% among 8th graders
(compared with a peak of 21% in 1996); 14% among 10th graders
(compared with a peak of 30% in 1996), and 22% among 12th graders
(compared with a peak of 37% in 1997).
Alcohol use remained nearly stable among 8th and 10th graders
as well, with nonsignificant decreases in the lifetime and past-year measures and nonsignificant increases in the past-month assessment.
