In many parts of the country they are about as low as anywhere else.
Losing your boundaries is why people like to drink alcohol, that's pretty much an inherent property. For many people it's more a matter of unwinding, greater confidence, etc rather than going full angry-violent-drunk, but to blame an underlying condition when hundreds of thousands commit crimes every year under the influence of alcohol is underselling the damage it has on society. I'd argue that because drugs more directly cause a person to lose their mind than guns, that they are more damaging to society on the whole.
