"Juveniles using drugs or alcohol committed 1 in 10 of the nonfatal violent victimizations against older teens. This was 2-1/2 times higher than the percentage of victimizations against younger teens perceived to be committed by a juvenile who was using drugs or alcohol.
"Younger teens were more likely than older teens to report that their juvenile offender was not using drugs or alcohol. In about 4 in 10 victimizations against younger and older teens committed by juveniles, the victim could not ascertain whether or not the offender was using drugs or alcohol."
