Table 7-2 shows the number of accession and attrition outcomes for persons given marijuana waivers compared with accessions and attrition outcomes for persons without any type of waiver for FY 2000 and FY 2001. The number of waivers range from 2,000 to 3,000 per year, which is only about 1.5 percent of total accessions. Interestingly, 12-month attrition rates are only slightly elevated for persons with marijuana waivers, by about 3 percent in both years (18 and 17 percent versus 15 and 14 percent, respectively). Also, it should be noted that attrition rates are somewhat higher for female drug waivers than male drug waivers, although the number of women receiving waivers is very small.

Attrition rates at 24 months are more elevated for those with marijuana waivers; the difference is 6 percent in FY 2000 and 9 percent in FY 2001. Even this difference is modest. Finally, the difference gets somewhat larger by 36 months. After three years of service, attrition rates are elevated by about 10 percentage points for marijuana waivers compared with persons with no waivers. It should be noted that this difference is
