What's the issue?
The Australian Institute of Health and Welfare says in 2022-23 around one in 20 people in Australia aged 14 and over reported using a medicine for non-medical purposes in the past 12 months.
This could mean using a prescription or over-the-counter medicine to get high, or to build muscle at the gym, for instance.
These were most often opioids (such as oxycodone and morphine), steroids, pharmaceutical stimulants (such as ones to treat attention deficit hyperactivity disorder or ADHD), and sedatives (such as benzodiazepines).
But these statistics don't tell us how these medicines were obtained. People might have bought them on the street, been prescribed them by multiple doctors, or by an individual doctor prescribing inappropriately. These stats also don't tell us if people obtained these just for their own personal use or if they sold any extra to others.
People can pay a significant mark-up for those drugs on the street, and the price varies according to the drug type. According to the StreetRx database, which crowdsources the street price of pharmaceuticals, Australians tend to pay A$1-$30 per pill.
