4. Based on a recent report by the Australian Bureau of Statistics (ABS) what percentage of unintentional drug overdoses were caused by Polydrug use?

To provide the most accurate answer, we would need to look up the most recent data from the Australian Bureau of Statistics (ABS) regarding unintentional drug overdoses and polydrug use. However, as I'm unable to access real-time data or external databases, I recommend checking the ABS website or recent reports that outline the statistics regarding unintentional drug overdoses specifically related to polydrug use.

Typically, reports from the ABS will present findings on the causes of drug overdoses, including specific percentages related to polydrug use. This data could be presented in various formats, including charts and tables, to illustrate trends over time.

For a complete and accurate response, please refer to the latest official ABS publications or relevant health statistics reports that focus on this topic.
