Are male or female Australian school students aged 12-17 years more likely to have used pharmaceutical drugs?

Among Australian school students aged 12-17 years, more 16-17 year olds than 12-15 year olds used analgesics in the past month (for either medical or non-medical purposes), while lifetime, past year, and past week use was similar among younger and older students.

Tranquillisers appear to be used (for non-medical purposes) at similar rates among younger and older students.
