•Substance use is significantly associated with the perpetration of cyber aggression.•Alcohol use is a greater risk factor for cyber aggression than other substances.•Adults are at greater risk of substance-related cyber aggression than adolescents.•Substance use was associated with cyber aggression among males and females. Prior research has demonstrated that various substances of abuse play a contributing role to acts of physical and verbal aggression. It is less clear if and to what extent substance use is associated with an increased risk in perpetrating cyber aggression, an emerging form of aggressive behavior that occurs through digital communication. A comprehensive review of the literature resulted in 15 studies and 18 unique samples from which effect size estimates were calculated. Analyses resulted in a moderate, significant mean observed correlation indicating that individuals who engaged in substance use were more likely than those who did not to perpetrate cyber aggression (r = 0.24, k = 18, 95% CI = 0.20, 0.28). Comparing data across types of substances revealed that alcohol use represents a stronger risk factor for cyber aggression than nicotine, cannabis, or other illicit drugs. Results also suggest a stronger relationship between substance use and cyber aggression among older than younger samples and in the context of intimate partner rather than peer aggression. Comparable estimates of substance-related cyber aggression emerged across types of cyber aggression and perpetrator gender. Further research is required to increase confidence in estimates used in moderation analyses. As with traditional aggression, alcohol use appears to represent a risk factor for cyber aggression, though it is unclear if the disinhibitory properties of alcohol are the mechanism of action for substance-related cyber aggression.
