> The DEA put Adderall on its list of the most abused medication, and limits production of it and investigates doctors who prescribe too much of it.

The other thing on top of limiting its production, it's not just for the US, it's worldwide.

Australia has a shortage of various types of ADHD medication due to this DEA production limit too.

Also, the Australian Government requested increased production to cover these shortages, and the DEA rejected that request.

So those limitations have a worldwide effect due to the US being one of only a few countries that produce these drugs.
