Support for cannabis legalisation likely comes from observing the legalisation of recreational cannabis in countries across the globe. Examples include Uruguay, Malta, Mexico, South Africa, Canada and a number of states in the United States.
Interestingly, very few Australians indicate they would use cannabis if it were legalised.
Over 78 per cent of respondents to the 2019 survey said that they would not use cannabis even if it was legal.
Only 9.5 per cent said they would “try it” and 9.2 per cent say they would “use it about as often as they do now”.
But asking voters if they support a policy proposal in the abstract might not tell us much about how much they’d support it once it becomes a hot button political issue.
We saw this play out in the 2020 New Zealand cannabis referendum. There, 51 per cent of voters rejected the legalisation of cannabis, despite early opinion polling in 2020 indicating strong support.
As the cannabis legalisation debate became a greater topic of discussion, support for legalisation gradually narrowed and finally flipped right before voting day. In the end, New Zealand narrowly voted no.
Opponents argued a normalisation effect could encourage teenagers to start using cannabis or that there would be more drug-affected drivers on the road. Some argued there would be unpredictable effects of lung health and mental health.
There is mixed evidence for each of these propositions, but the debate itself made voters more cautious about change.
One of the big lessons from the last few decades of cannabis law reform is voters prefer a gradual and measured approach to drug liberalisation.
Voters need to be convinced the legalisation of currently illicit drugs will successfully reduce health and social harms.

One academic analysis of the failure of the New Zealand referendum noted the proposed bill failed to address voter concerns about potency, reducing the black market and the normalisation of cannabis.
A libertarian style argument in favour of cannabis legalisation focused on the “freedom to choose” is unlikely to shift voters already concerned about the harms of legal substances such as alcohol and tobacco.
A more moderate approach, centred around harm reduction and best practice regulation, is more in line with the values of voters.

Jumping straight from a criminalised environment regarding cannabis towards full legalisation may also be too fast for some voters. A gradual change of policies regarding cannabis is more likely to have support.
For example, states that adopt medicinal cannabis policies (as Australia has done) tend to move faster towards recreational cannabis legalisation than other jurisdictions.
One intermediate step, which has already occurred to varying degrees in the ACT, Northern Territory and South Australia is the decriminalisation of the possession and use of cannabis.
There has been strong consistent support for the decriminalisation of cannabis in all states and territories in Australia for a number of years now.
Decriminalisation provides a good introductory step towards treating cannabis use as a health issue, not a criminal justice one.
Overall, there’s a growing level of support for cannabis law reform in Australia. But change is likely to occur much slower than liberalisation supporters would hope.
