Electronic vaping products emerged in the late 1990s as an alternative mode of cannabis use. While the rapid increase in nicotine containing vape products has been well documented, there is also some evidence of an increase in cannabis vaping. Further, evidence from North America suggests that preference for cannabis products may be shifting. However, changes in patterns of cannabis use in the Australian context have received comparatively little attention.

This bulletin examines the recent use (2014-2024) of non-prescribed cannabis and/or cannabinoid-related products among two samples of people who regularly use drugs in Australia, including routes of administration and the types of products used.
