Police in Sydney, Australia announced that children as young as 12 are using ice. 

From The Daily Telegraph:

SYDNEY children as young as 12 are experimenting with the highly dangerous drug ice because they see it as glamorous, senior police say.

The disturbing development has been revealed by police, who are rolling out a series of community forums on ice, targeting children aged 12 to 18.

As part of the campaign, a drug and alcohol expert would emphasise to girls that the drug can ruin their appearance, with sores developing from use.

Older teen boys would be told it caused lack of erectile function.
