Our aim was to disseminate research results about the very high rates of cannabis use in three remote Aboriginal communities in Arnhem Land, Northern Territory, to the study populations. To achieve this we translated prevalence estimates, using local concepts of life stages, numbers and quantities. The reaction of the local community to results presented in this way was characterised by the phrase used when understanding something for the first time: Wa! Ningeningma arakba akina da! ("Oh! Now I know, that's it!"). To successfully disseminate research findings in these communities, it is critical to undertake comprehensive community liaison, to find common conceptual understandings and to build the skills of local Indigenous researchers.
