Could it be that drinking Grolsch and smoking weed makes safer cyclists than drinking Fosters or XXXX
On this note, there's as much drugs in AU as in NL and of course plenty of booze in both countries. Outside of here, I help run a youth lifestyle forum which is based around the dance music scene and as such gives a lot of harm reduction advice about drugs and helps people seek appropriate assistance when they have overdone it.
NL is of course a relatively tolerant nation (though its no longer and in reality never has been the hedonists paradise its claimed to be - its more that they have
pragmatic laws about drugs than they accept everyone doing them).
Australia goes for far heavier regulation, to the point of overrulling "Western" standards of free speech, its technically illegal to discuss drug use on the Internet in Australia.
The young people on our site from NL seem to balance their partying and other life responsibilities and rarely get health problems from thelir lifestyles and drug/alcohol use, whereas many from Australia seem to be suffering serious mental and physical health problems including young people being addicted to class A drugs in their early 20s.
with regard to transport, here a true word is said in jest - the Dutch kids if they have been clubbing or raving take the train or their bike to get back and forth, they ride slower and more carefully and rarely get into accidents,whereas youths in AU or even UK are much more likely to drive under the influence and get into a injury or fatal collision.
So as for regulatory/research approaches, I know which countries research I have much more respect for..
Also they've got better music, I'd much rather hear Tiësto or Armin Van Buuren than most Australian pop music
