It is quite common outside of the US. Actually I think other places are generally better with binge drinking in the late teenage years, but one of the few ways America really did seem to have a lead over the rest of the world in personal health was that we were able to cut down on teen smoking for a while. Then vaping got invented and I’m sure it’s a huge problem again.

But I agree laws have a huge effect.

It's their parents having significant effect, friend. Kids don't care about drinking laws.
