Notes:

*

p<.05; CAN = Cannabis Users; PASAT = Paced Auditory Serial Addition Task; Fisher’s Z comparisons were run to determine whether correlation coefficients significantly differed between CAN and controls.

1

Region identified from Cannabis*VO2 analysis; controls demonstrated a more robust positive relationship between VO2 max and volume.

2

Regions identified from Cannabis*Sex analyses where CAN-using males had smaller volume compared to non-using males.

3

Regions identified from Cannabis*Sex analyses where CAN-using females had greater volume compared to non-using females.

4

Regions identified from Cannabis*Sex analyses where CAN-using females had smaller volume compared to non-using females.
