This web-based release presents a summary of the national findings from the 2016 National Drug Strategy Household Survey. The 2016 NDSHS show that younger people (aged under 30) were smoking less, drinking less and using fewer illicit drugs in 2016 than in 2001. However, for people in their 40s, 50s and 60s, there was little to no change in drug usage behaviours over this period but their use of some drugs has increased between 2013 and 2016.
