Chapter 5 Illegal substance use
8.2. Consequences related to violence as perpetrator
Graph 8.2.1- Percentage of persons 12-65 years of age that reported having committed some type of violence under the effect of alcohol or illegal drugs in the
previous 12 months, according to type of aggression - Brazil, 2015

Estimates by sex and age bracket
Approximately 4.4 million persons reported having argued with someone under the effect of alcohol in the 12 months prior to the interview; of these, 2.9 million were men and 1.5 million were women. The prevalence of having reported that they had
“destroyed or broken something that wasn’t mine” under the effect of alcohol was also significantly higher in men than women (1.1% and 0.3%, respectively).
Estimates of violence perpetrated by individuals while under the effect of alcohol and/or illegal drugs were highest among younger men and women (18-24 years of age, with differences by gender), with downward proportions in young adults (25-34 years) and generally decreasing with age in both men and women (Table 8.2.1).

Estimates by level of schooling
Among individuals 18 years or older, there were no statistically significant differences according to levels of schooling for prevalence of violence perpetrated under the effect of alcohol (Table 8.2.2).
A significantly smaller proportion of persons with complete university education or more (0.2%) reported having argued with someone under the effect of drugs, when compared to those with no schooling or incomplete elementary (0.8%). There was no significant difference for the other types of violence committed under the effect of drugs.

Estimativas para os domínios geográficos da amostra
For the estimation domains, each type of violence is presented in one of the Tables 8.2.3 to 8.2.5. A complex pattern was observed, with higher prevalence of violent events associated with alcohol in certain domains, such as Northeast Brazil and medium-sized municipalities.
However, these differences were not statistically significant, with marked overlapping of the respective confidence intervals.

The pattern for alcohol differed from that of outcomes associated with the consumption of illegal drugs, with higher prevalence in Central-West Brazil and in the set of state capitals, although here, too, the confidence intervals basically overlapped.
