Between 2002 and 2003, the number of 12 to 17 year olds reporting daily use of marijuana decreased from 358,000 to 282,000; while there were no changes in the number of daily marijuana users among 18-25 year olds or adults age 26 or older.
  • An estimated 39.2% of daily marijuana users were dependent on or abused marijuana compared with 13.5% of less-than-daily marijuana users.
  • Daily marijuana users (63.3%) were more likely than less-than-daily marijuana users (38.8%) or non marijuana users (4.6% ) to use another illicit drug. Daily marijuana users also were more likely to be current cigarette smokers and heavy drinkers.
  • More than half of daily marijuana users (53.3%) reported dependence on or abuse of alcohol or an illicit drug compared with those who were less-than-daily users (35.5%) and nonusers (5.6%).
