Our findings indicated that while non-binge drinking is associated with violent behavior only at age 13, binge drinking was found to be robustly associated with violence among youth up through age 20; however, interestingly, the relationship dissipates when youth arrive at the legal drinking age of 21. Results suggest that alcohol and violence are interrelated in the lives of youth, but their association appears to be dependent on the youths' age and on the nature and severity of their alcohol use.
