Make the legal drinking age 18

It seems a bit ridiculous that the age to buy cigarettes is less than alcohol, which has less hazardous to our health. And the fact that kids are being sent to war zones to potentially die and they cant enjoy a beer is appalling, and other countries around the world have gotten by with having lower drinking ages and having little to no problems, its stupid to think that something as poisonous as cigarettes with all its hundreds of cancer-causing chemicals are on shelves for anyone 18
