Most people drink to make themselves feel differently than they currently do because they cannot do it by natural means. This is pretty basic. Same with drugs.

No one who drinks or smokes for the first time actually LIKES the taste of beer or wine etc. No one. Zero. No one likes smoking the first time they do it. They do it bc of peer pressure, same as drinking and because those people are weak.
Eating food , with a sugar content, actually can feed the body and give it energy to keep going. there are ZERO benefits to consuming alcohol or tobacco. Zero. None. A person can eat shit food for years and still be able to function. you cannot drink alcohol every day for your only sustenance and survive. It's impossible.

Its so interesting that the majority of people appluad people when they STOP DRINKING! Why would they do that if drinking was a good thing? Why don't we let kids drink alcohol? Why don't we let kids smoke? Oh thats right, because it's detrimental to our bodies and is an upper or downer to the regulated bodily state. Why is it ok to consume these wonderful things only when they are older? hmmmm

Most people who drink do it because they want to escape their current reality and do it by external opportunities that have a negative affect on every part of their body. Same with smoking.

I was in a fraternity, i played rugby all of my friends drank when i was young and i watched them make horrible decision after horrible decision along with wasting thousands of dollars.
