Past year marijuana users aged 18 to 22 who were in college were more likely than their counterparts who were not in college to have gotten their last marijuana for free (66.3 vs. 52.3 percent) and were less likely to have bought it (32.7 vs. 45.6 percent). Males aged 18 to 25 were more likely than their female counterparts to have bought their last marijuana (47.7 vs. 29.7 percent) and were less likely to have gotten it for free or traded for it (50.0 vs. 69.5 percent).
Among young adults aged 18 to 25 who were past year marijuana users, 86.7 percent obtained their most recently used marijuana from a friend either for free or by sharing it (Figure 2). Males and females who obtained their most recently used marijuana for free were equally likely to have gotten it from a friend; however, males were more likely than females to have gotten it from someone they just met or did not know well (8.5 vs. 4.0 percent) and were less likely to have gotten it from a family member or relative (5.6 vs. 8.6 percent). Among past year users who obtained their most recently used marijuana for free or by sharing it, those who used marijuana on a daily basis were less likely than nondaily users to have gotten it from a friend (76.3 vs. 86.9 percent) and were more likely to have gotten it from someone they just met or did not know well (16.3 vs. 5.8 percent).

The National Survey on Drug Use and Health (NSDUH) is an annual survey sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA). Prior to 2002, this survey was called the National Household Survey on Drug Abuse (NHSDA). The 2002 data are based on information obtained from 23,066 persons aged 18 to 25, the 2003 data on information obtained from 22,738 persons aged 18 to 25, and the 2004 data on information obtained from 22,829 persons aged 18 to 25. The combined 2002, 2003, and 2004 data are based on information obtained from 68,633 persons aged 18 to 25, of whom 20,086 used marijuana within the year prior to the interview date. The survey collects data by administering questionnaires to a representative sample of the population through face-to-face interviews at their place of residence. The NSDUH Report is prepared by the Office of Applied Studies (OAS), SAMHSA, and by RTI International in Research Triangle Park, North Carolina. (RTI International is a trade name of Research Triangle Institute.) Information on NSDUH used in compiling data for this issue is available in the following publications: Office of Applied Studies.
