Figure 6.3 is titled "Lifetime, Past Year, and Past Month Cigarette Use among Youths Aged 12 to 17: 2002 through 2004." It is a bar graph, where time periods of use (lifetime, past year, and past month) are shown on the horizontal axis, and the percentage using cigarettes is shown on the vertical axis. For each of the time periods of use, there are bars representing 2002, 2003, and 2004. Tests of statistical significance at the .05 level were performed between 2003 and 2004 estimates and between 2002 and 2004 estimates; significant results are indicated where appropriate.

Among youths aged 12 to 17, the percentage using cigarettes in their lifetime was 33.3 percent in 2002, 31.0 percent in 2003, and 29.2 percent in 2004. The differences between the 2004 estimate and the 2002 and 2003 estimates were significant.
