In the 2016 National Drug Strategy Household Survey (NDSHS) around one in six (16.8%) of Western Australian’s aged 14 years and older reported using illicit drugs in the previous 12 months. This is stable in comparison to the 2013 survey results (17%), but was slightly higher than the national average of 15.6 percent.3, 4
In 2016, illicit drug use was the highest among the 20-29 age group, of which 29.8 percent reported use in the last 12 months (see image below), however this was higher than the national average of 28.2 percent.4
