In the minor parties debate tonight, Tariana Turia, Winston Peters and Jim Anderton supported raising the drinking age back to 20. Rodney Hide did not support this, nor did Peter Dunne or Jeanette Fitzsimons, who both pointed out that the problem binge-drinkers are the 13-year-olds, for whom alcohol is illegal anyway. In their opinion changing the drinking age would not affect this at all.
I disagree. Where are these 13-year-olds getting their alcohol from? Sometimes their parents, but not normally enough to really get them into trouble. I would suspect they are primarily getting it from 18-year-old friends.
Raising the age from 18 to 20 won’t stop 18-year-olds drinking. They have always been able to obtain alcohol from their older friends. But it will make it a lot harder for 13-year-olds to obtain alcohol, because they will usually have fewer 20-year-old friends. So raising the drinking age should be an effective way of combatting teenage alcohol abuse.
