Figure WORK 6. Percentage of Adults Who Used Cocaine or Marijuana or Abused Alcohol, by Age: 2005

In 2005, young adults (ages 18 to 25) were more likely than older adults to report alcohol abuse, marijuana use, or cocaine use in the past month. For example, about one in six (16 percent) adults ages 18 to 25 reported using marijuana in the past month during 2005, compared with 9 percent of adults ages 26 to 34 and 3 percent of adults ages 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 young adults, heavy drinking and marijuana and cocaine use increased between 2004 and 2005 while heavy drinking and marijuana use declined for adults ages 35 and over, as shown in Table WORK 6.

Note: Cocaine and marijuana use is defined as use during the past month. “Binge Alcohol Use” is defined as drinking five or more drinks on the same occasion on at least one day in the past 30 days. “Heavy Alcohol Use” is defined as drinking five or more drinks on the same occasion on each of five or more days in the past 30 days; all Heavy Alcohol Users are also Binge Alcohol Users.
