  • There were two non-binary participants in total, one a psychologist in each condition. They were removed from χ2 analyses, as most groups had zero non-binary participants. Gender, trainee and stance on decriminalisation were assed via χ2 analysis. Age and years of experience were assessed using two-way ANOVA grouped by vignette condition and profession. Main effect of vignette condition: *p<0.05. Main effect of profession: p<0.05, ††p<0.01, †††p<0.001.

  • ANOVA, analysis of variance; MDMA, methylenedioxymethamphetamine.
