The relation between alcohol and violence is not yet fully understood, as its impact on different individual varies. While alcohol use correlates positively with crimes and violence, there is no simple, causal and direct relationship. Studies and theories of alcohol use disorder suggest, among others, that use of alcohol likely reduces the offender's perception and awareness of consequences of their actions.[1][2][3][12] The World Health Organization has noted that out of social problems created by the harmful use of alcohol, "crime and violence related to alcohol consumption" are likely the most significant issue.[5]
