1Alcohol does not add anger. It takes off the brake. Stimulants do the opposite job and press harder on the accelerator, and having both in you at once is the worst arrangement of the two.

A stimulant leaves that part in place and floods everything with drive and urgency instead. Knowing which one you are dealing with tells you what to expect from an evening, and it explains why the mixture goes wrong so reliably.
Islamic evidence

Psychological evidence
The alcohol myopia model, set out in a review of this literature, explains disinhibited aggression as attention narrowing onto whatever is provoking while everything that would have held you back drops out of view.

Treat it as a way of understanding what happened rather than a measurement of it.
