Roy Morgan’s latest data shows that 48% of Australians now support legalising marijuana, up 15 percentage points over the past decade (from 33% in 2015 and 42% in 2019). Opposition has fallen to 41%, also down 15 points since 2015 (from 56% and 49% in 2019), while 11% remain undecided. Men are more inclined to back legalisation of marijuana, with 51% saying it should be legal (40% opposed) compared to 45% of women (42% opposed). All Australians aged 18–49 now show majority support for legalisation; 18–24-year-olds have seen support grow from 36% in 2015 to 50% in 2019 and now 54% (an 18-point gain over the decade). Support among 25–34-year-olds has surged from 34% in 2015 to 46% in 2019 and now 58% (a 24-point increase). Middle-aged groups are also shifting: 35–49-year-olds now show a majority in favour at 51%. Meanwhile, support among 50-64-year-olds has risen 19 points to 48%, while opposition in this age group has fallen 18 points since 2019. Among those aged 65 and over, support has edged up slightly (from 33% in 2019 to 36% in 2025), yet this group continues to record the highest opposition at 54%.
