From the article:

The 2011 Annual Report (the eighth annual report) was released on 17 October 2012. The report confirmed between 2004 (the first year for which figures are available) and 2010 per-capita ADHD child prescribing rates fell from 2.25 % to 1.3%.3 Federal Government figures4 indicate the number of children on ADHD medications in WA peaked in 2002 at 2.6%, indicating a 50% fall from the peak. Over a similar timeframe (2002 to 2008) amphetamine abuse rates by West Australian teenagers fell approximately 51% supporting the contention that if you stop giving teenagers amphetamines they stop abusing them.5
