This year, pro-21 researchers Kitt Carpenter and Carlos Dobkin are at it again. As you may recall, we at Twenty-One Debunked have critiqued much of their past work, particularly their use of the "regression discontinuity" approach. The researchers found a significant jump in statistical death rates, arrests, and stuff like that immediately after young people turn 21 compared with before. And their latest study seems to be more of the same, this time looking at non-fatal injuries as measured by both ER visits and inpatient hospital admissions.
Oddly, these researchers actually (and without even a hint of irony) claim that these studies show that the 21 drinking age is effective in saving lives and reducing alcohol-related harm! But we at Twenty-One Debunked see it rather differently--if anything, it shows that there is nothing at all magical about turning 21 that makes one invulnerable to the deleterious effects of excessive alcohol consumption. And setting the drinking age at such an arbitrarily high age only sets a powder keg (pun intended) that goes off when young people reach that age. The higher the drinking age, the larger the powder keg, it seems. And it also shows that the Law of Eristic Escalation (i.e. imposition of order leads to escalation of chaos) is correct, as well as Fenderson's Amendment (the tighter the order is maintained, the longer it takes for the chaos to escalate, but the more it does when it does). Hardly a ringing endorsement for the 21 drinking age!
Of course, Carpenter and Dobkin also find evidence of a jump in both drinking and alcohol-related deaths among Canadians upon reaching their MLDA (18 or 19, depending on the province), particularly among males, and the increase in mortality seems to be due to a sudden jump in "extreme" binge drinking. It seems there is always a risk of increased alcohol-related harm in the short-run after suddenly turning legal, regardless of age. But as much other research shows, there is good reason to believe that such an effect is worse and longer-lasting when the the legal drinking age is higher rather than lower. And furthermore, a recent study in Australia (where the drinking age is 18 and DUI laws are tougher) found essentially no link between being able to drink legally and motor vehicle accidents of any type in the state of New South Wales. Food for thought indeed.
On the plus side, one should also note that another recent study using a regression-discontinuity approach found that being able to drink legally reduced the consumption and initiation of hard drugs (cocaine, heroin, meth, etc.) among young people. That blows yet another hole in the junk science that is the "gateway" theory.

Research done by the pro-21 drinking age side is a bunch of nonsense. The research from Australia would be equally applicable to the United States if the drinking age were 18. That research would also be applicable to Canada if the drinking age was 18 everywhere. The truth is that a higher drinking age does more harm to young people than a lower drinking age of 18. The drinking age should be 18 and it would be effective.
