Should the drinking age be 18 in the US?

Along side many other countries that drinking is 18 the U.S is one of the few countries that drinking age is 21 with this being said the U.S should drop the legal drinking age to 18 because it would reduce alcohol abuse, children be more comfortable with discussing or using alcohol in front of adults and will be fairing judge by other social drug problems. Alcohol abuse has a lot to do with children who drink underage, a lot of kids can state that being involve in something illegal makes them feel cooler or the act feel ten times better. If the legal drinking age was 18 then it would be a less time for a teenager to wait to drink it also begins to lose the hype or the good feeling of doing something illegal, and if alcohol usage is common then there is more education on the use of alcohol and kids wont abuse it because they can always get it or go to a bar for it which will result into more overseeing of people who are drinking. If kids can drink at 18 they would feel more comfortable talking to a parent about drinking because the fact lies with them be legal they are not committing a crime and their parents can give them the right advise rather then kids abusing it with there friends until the age of 21 then they build a addiction that could have been prevented. One point that does not make sense to me is that in certain state kids the age of 18 can buy cigarettes or weed also serve in the military which all can possible lead to death but can not buy alcohol which simply does not make sense to me. In conclusion allowing drinking at a early age can prevent a lot of issues the U.S face today with young adults and alcohol addictive with a earlier drinking time.
