Chess players eat a healthy meal that gives them energy to think. Alcohol will only impair you.

Well I already have the govt breathing down my neck so I"ll just be vague - drugs that increase your concentration and memory temporarily or long term does exist although I wouldn't recommend doping for sports or chess as they have short/long term side effects as well but if you're in a war or a dangerous country, they'll dramatically increase your survival rate
the best alternative that's legal in most countries would be a mix of caffeine and alcohol like the classic 4 loco
drugs aren't bad, addicts are dumbasses and mostly dumb teens don't know the proper purpose of each drug and just want to get high.Making them illegal is bad because it creates mafias and more crime
