This is an interesting topic. I totally agree that if kids are exposed to it early then they are less likely to have a problem. 14 is a good age but i dont think that you should be say allowed to buy it at a bar, or go to a club. More go to a liquor store and get some. Maybe even a limit that you are allowed to buy at once would be good but of course you could just get all your friends together and do it.
I agree that if its part of the culture and if its encouraged as a social thing then kids are going to do better. I am more of a social drinker myself and i love beer, i think that some kids simply want to rebel, so they're parents tell them no alcohol at all and they go out and do the complete oppisite. The government needs to realise that you cant stop underage drinking or anything like that, people are smart they will just find new ways to not get caught.
One thing i liked about my old school was during the classes that they discussed drugs in, they said to us bluntly 'We know that nothing we do is likely to change you from trying drugs, its your own choice.' they accepted it, and so they taught us instead about the effects of drugs, what to expect, why they are bad for us etc. and let us have our own opinion, but a well educated opinion.
Thats what the government needs to do, they need to realise they will NEVER stop underage drinking, same as the fact that they will never stop illegal drugs etc. Instead they should make sure children and teenagers are well educated about the effects of alcohol, what it can do to you. Rather than having a stiff NO ALCOHOL angle they should focus more on social drinking, having two standard drinks in the first hour and one every hour after etc. I know, being a teenager, that this would definitly sway my opinion better than DONT DRINK OR YOU WILL BURN IN THE FIREY PITS OF HELL.
I know that when i am a parent my kids will be exposed to alcohol at a youngish age. But i will always encourage them to drink socially rather than get smashed daily. I think that politicians need to realise this, as does the general population.
