Answer:
violence
Explanation:
The relationship between drugs and violence is studied among the border between Mexico and the US, since illegal production and distribution of these drugs has increased the number of deaths.
Drugs enable people to engage in risky behaviours that make them more likely to engage in violent behaviour. Most neuroscientists argue that drugs trigger specific mechanisms on the brain that make people act different and violent ways. They can take risky decisions to consume drugs and experience other states of mind.
The US - Mexico border is an area of ongoing and increasing violence, and so does the situation in the Peruvian, Bolivian and Colombian border.
And other social factors are to be accounted for this, while drugs not necessarily relate to crime, the presence of drugs makes violent crimes more likely and therefore the rate of crime in areas consuming illegal drugs increases significantly.
