Rob does bring up some good points, but I think that the experience of the rest of the world will back me up. If alcohol consumption in the late teens slows brain cell production, wouldn’t the majority of Europe be dumber than us? After all, many European countries have ridiculously low drinking ages and more accessibility to alcohol at any age. They aren’t any dumber than us, right?
About high school students getting their hands on alcohol, this is where my plan about needing a diploma comes in. Of course, even if the age were simply 18, I don’t think the effects on high schoolers would be as profound. In my experience, those in high school who wanted to drink were able to get their hands on it in some way or another, I honestly never knew how. Those who weren’t really interested in drinking didn’t worry about finding people to buy it for them, and I think this would stay the same, even if a few high school seniors were able to buy it.
I will stand by my earlier argument that drinking in 18-20 year olds would decrease, but I will modify it slightly from how Rob worded it. Drinking itself might not decrease, but binge drinking would. I know that the point of alcohol at a party is to loosen people up a bit, but if people were able to buy their own alcohol they wouldn’t be so prone to overdoing it when they go to a party. Sure, a few people just like drinking too much, and they would continue getting wasted no matter what, but I think that overall, less people would be among that crowd. Just like there are less adults over 21 who get wasted all the time than people who just drink a little to loosen up, I think the 18-20 crowd would become that way as well.
Finally, on Rob’s drunk driving argument: I don’t think lowering the drinking age would have much effect at all on drunk driving. This is unfortunate because we really need to find a way to lower the frequency of these tragedies, but I don’t think that lowering the drinking age would increase them. There are plenty of 16-21 year olds who drive drunk as it is now, and for the most part they are in the same crowd as those who drink too much routinely; they are going to continue in the same pattern whether it is legal or not. For the rest of us, the harsh drunk driving laws are deterrent enough to keep us off the road if we’ve been drinking, let alone the fear of death or killing someone. I don’t think that there is so much difference between 21 and 18 year olds that 18 year olds think it is OK to drive drunk. By the time we are 16 and we get our drivers licenses, we know that it is a horrible idea, and waiting until we are 21 isn’t going to cement that any more than it will already be cemented when we are 18.
