Six hundred and six individuals completed an interview with the SSAGA. Overall, the demographic characteristics of the sample, including mean age (30.4 ± 11.85 yrs), years of education (11.6 ± 1.6 yrs), economic status (47% of the sample had an annual household income < $20K), employment (44% of the sample had any current employment and 32% of the sample had current fulltime employment), and current marital status (single= 65%, married =19%, divorced=8%, separated=7%, widowed=2%), are similar to available information for the tribe from U.S. census data (United States Bureau of the Census 1990). Forty-four percent of men and 26% of women had lifetime DSM-III-R cannabis dependence. Demographic characteristics of participants with and without DSM-III-R cannabis dependence were compared. There were no significant differences between the groups for age, economic status, employment, marital status, and Native American Heritage. Compared to participants without cannabis dependence, participants with cannabis dependence were more likely to be male (p<0.001), younger (p<0.05), and have fewer years of education (p<0.01).
