Notes
1. Smoking status in 2010 has been revised. Trend data may not match previously published results.
2. The calculation of drinking status and alcohol risk variables was updated for all years in 2019. Trend data may not match previously published results.
3. In 2016, pain-killer/pain-relievers and opioids sections were combined into one section and references and questions about use of non-opioid over-the-counter drugs such as paracetamol and aspirin were removed. Data are not considered comparable to previous survey waves.
4. The NDSHS offers introductory text for each class of drug, including examples of the drugs included. Examples for hallucinogens, inhalants and New and Emerging Psychoactive Substances were changed in 2019, which may have impacted trend results since 2016.
5. State results do not include data from the 8 Indigenous remote communities interviewed in the NT in 2019. These data are included in national estimates.
6. Age-standardisation has been revised in 2019. Trend data may not match previously published results.
