Older Australians: High Drug Use Linked to Stress and Trauma

In a large Australian survey, about 42 percent of people aged 45 and older said they had used an illegal drug in the last year. The study looked at 7,862 participants, which represents roughly 8.7 million individuals across the nation. This figure shows that drug use is not just a youth problem; it affects a significant portion of the older population.

Several personal and community factors were tied to higher drug use. Those who were born in main English‑speaking nations were more likely to report use. People living in inner‑regional areas also showed higher rates. Mental health played a big role: moderate stress raised the odds, and high or very high stress raised them even more. Lower scores on mental‑health questionnaires and a history of traumatic events also increased the likelihood of using drugs.

Other lifestyle habits were connected to drug use as well. Smoking and risky drinking often appeared together with illegal drug use. Poor mental health and past trauma created a pattern where substances were used as a coping tool. The findings suggest that programs should treat substance use and mental health together, rather than in separate silos.

Overall, the data highlight a hidden challenge among older adults. The high prevalence and the mix of risk factors mean that health services need to look beyond age stereotypes. Integrated care that addresses stress, trauma, and related behaviors could help reduce illicit drug use in this group.
