Highlights: Based on SAMHSA's 2003 National Survey on Drug Use and Health, 3.1 million persons aged 12 or older used marijuana daily, that is, on 300 or more days. 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 an illicit drug compared with those who were less-than-daily users (36.5%) and nonusers (5.6%). By combining three years of data from SAMHSA's National Survey on Drug Use and Health from 1999 to 2001, SAMHSA's Office of Applied Studies was able to produce substate estimates of substance use. In 1999 to 2001, past month use of marijuana varied from 2.3% in Northwest Iowa and 2.6% in Southern Texas to 10.3% in Boulder, Colorado and 12.2% in Boston. Of the 15 substate areas with the highest rates of past month marijuana use in the United States, five were in Massachusetts, three were in California, and two were in Colorado.
Cocaine The percentage of youths aged 12 to 17 who had ever used cocaine increased slightly from 2001 to 2002 (2.3 to 2.7 percent). Among young adults aged 18 to 25, the rate increased slightly from 14.9 percent in 2001 to 15.4 percent in 2002. From 1965 to 1967, only 0.1 percent of youths had ever used cocaine, but rates rose throughout the 1970s and 1980s, reaching 2.2 percent in 1987. A period of decline followed in the early 1990s, after which the trend reversed, reaching a peak at 2.7 percent in 2002. The percentage of young adults aged 18 to 25 who had ever used cocaine was below 1 percent during the mid-1960s, but rose steadily throughout the 1970s and early 1980s, reaching 17.9 percent in 1984. By 1996, the rate had dropped to 10.1 percent, but climbed to 15.4 percent in 2002.

In 2001, about two thirds (67 percent) of new marijuana users were under age 18. This proportion has generally increased since the 1960s, when less than half of initiates were under 18 (Figure 6.1). The average age of marijuana initiates was around 19 in the late 1960s and 17.1 in 2001. Since 1975, about half of marijuana initiates each year were females (51 percent in 2001). Prior to 1975, females comprised fewer than half of new users, on average. Since 1965, the average age of female initiates has generally been slightly higher than the average age for male initiates.
