(Theoretically at least: naturally there are people who take such taboos more or less seriously. Previous line manager was an Iranian with Zelda tattoos).
My only data point is anecdotal: my dad had bowel cancer, didn't change his water consumption after the surgery, insisted he was drinking plenty even while the nurse was putting a drip in one arm to rehydrate him and the other arm to give meds because he'd almost destroyed his kidneys.
Habits can be hard to change, and self-awareness slow.
I live in Kashmir, India (unfortunate) anyway, historically we have been pretty isolated from general mass market societal pressures plus strong religious affiliation means people as a society don't like alcohol.
Until last year I think there used to be a single wine shop for like 8 million population. Since then governmental pressure brought more and more shops but natives still don't accept it.
We have a huge tourist population who comes here and they are the customers + army.
Natives have not consumed alcohol for centuries and there doesn't seem to be a cultural shift towards acceptance so I can say the problems associated with alcohol are just not here.
No one gets diagnosed with alcohol liver disease or gets into drunk driving accidents or family abuse stuff.
Not do people get into addiction (drugs have been forcefully introduced)
