  • CUD = cannabis use disorder; NCUD = no cannabis use disorder; SEβ = standard error of β.

  • * All results are adjusted for age, slice thickness and intracranial volume. Significant from p < 0.01.

  • Adjusted mean difference between the 2 groups.

  • Calculated only for significant regions of interest.

  • § Based on the FreeSurfer segmentation output.

  • Based on the FreeSurfer Desikan-Killiany Atlas.
