For example, more than one in six (17 percent) of adults 18 to 25 reported using marijuana in the past month during 2003, compared with 8 percent of adults 26 to 34 and 3 percent of adults 35 and older.
- The percentage of persons reporting binge alcohol use was significantly larger than the percentages for all other reported behaviors across all age groups, as shown in Table WORK 6.
- Among all adult age categories, the use of cocaine, marijuana and alcohol abuse did not increase or decrease more than 1 percentage point between 2002 and 2003, as shown in Table WORK 6.
