The drinking age should be lowered to eighteen because that is the age of a legal adult, it is not constitutionally correct to set the drinking age at the federal level, and because it will cut the numbers in binge drinking.At age eighteen the government feels that you are responsible enough to vote, serve on a jury, live on your own, drive, smoke, buy weapons, go to an adult prison, get married without parental consent, and go to war. … Yet, in 1972 when congress lowered the voting age to eighteen some states also lowered the drinking age. In 1984 congress passed the National Minimum Drinking age to 18years.
