It is not possible to successfully eliminate alcohol. Prohibition was a flop.
Alcohol is natural and exists throughout the world and in the human body without drinking it and without any intervention. It is a product of a natural fermentation process that even occurs in places not inhabited by humans, sometimes intoxicating wildlife. Besides, alcohol is used in for sanitizing and cleaning, and it works very well, besides for being less toxic than other cleaners.
(There are many drugs that get you even more high than any of the ones you hear about, with the side effect of death in most people who take them.)
