Also if I go drinking with someone I don't know well, the risk of their becoming violent is quite high.
Alcohol happens to have 10,000 years of cultural tradition behind it. Plus, it pairs well with food.
In what kind of society or social circles is this true? Here it's common to socialize and meet strangers over a drink or two, and the risks of their becoming violent is near zero.
Maybe but it's also much harder to obtain due to being illegal.

Jesus who are you going drinking with??? That's not normal.
> On average, roughly 100% of inmates who are incarcerated for violent offences have two arms.

Like someone here writes, correlation does not imply causation, but correlation is evidence of causation, and that is a strong correlation. Specifically, if the person you picked is under the influence, he or she is 10.4 times more likely to be engaging in an act of violence than if he or she is not.
