Program and control group youth reported no differences in their drinking or marijuana use.
As shown in Table IV.4, 16 percent of program group youth and 19 percent of control group youth reported smoking cigarettes in the last month, a difference that is statistically significant (p-value = 0.07). However, with respect to alcohol and marijuana use, behaviors more closely associated with risk behavior, there are no statistically significant differences between the program and control group youth. Overall, about one in four youth in both groups reported drinking once a month or more, while 30 percent reported ever having used marijuana.

Alcohol and drug use varied considerably across the program sites, and this is due at least in part to the variation in the ages of the study youth. Within each site, however, program and control group youth reported no statistically significant differences in either behavior. Differences between the two groups also varied in direction. For example, program group youth in ReCapturing the Vision reported rates of alcohol use six percentage points lower than corresponding control group youth, while program group youth in FUPTP reported rates five points higher than corresponding control group youth. Neither difference is statistically significant (p-values = 0.16 and 0.11, respectively).
