Similar age effects were found in intending to use cannabis as often or less often. There was broad\u2010based shift in attitudes for people wanting to try cannabis (2007: <jats:italic>b<\/jats:italic>\u00a0=\u00a0\u22120.51 [\u22120.82, \u22120.21]; 2019: <jats:italic>b<\/jats:italic>\u00a0=\u00a00.68 [0.38, 0.98]) or use cannabis more often (2007: b\u00a0=\u00a0\u22120.15 [\u22120.50, 0.20]; 2019: <jats:italic>b<\/jats:italic>\u00a0=\u00a00.83 [0.49, 1.18]). The population trend of weekly cannabis use decreased in the earlier periods but increased since 2013 (<jats:italic>b\u2009=<\/jats:italic>\u2009\u22120.13 [\u22120.25, \u22120.02] vs 2019: b\u00a0=\u00a00.06 [\u22120.09, 0.20]). This suggests that legalisation would increase uptake of cannabis and consumption among current consumers. There were distinctive inter\u2010generation variations: people born between 1950s and 1960s had more liberal views towards cannabis use than people born before or after (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). There were indications that young people born in the 1990\u2009s are catching up with the baby boomers in using cannabis more often if it was legal.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion and Conclusions<\/jats:title><jats:p>There has been a population\u2010based shift in Australia in favourable attitudes towards cannabis use, more so among those born in the 1950s to 1960s than other generations. Liberal attitudes and more frequent cannabis use may put certain cohorts at higher risks of cannabis dependence and related
