Fig. 4 — Effects of marijuana use on subcortical shape in the full sample of users. (A) Trend for significant negative relationship between number of times used and scalar values in the left amygdala. Participants with a higher number of times used showed more inward deflection in the superficial group of the left amygdala. FWE-corrected p < 0.08. Saggital slice (left), Coronal slice (middle), Axial slice (right) (B) Significant positive relationship between age of first use and scalar values in the right nucleus accumbens. Participants with a earlier age of first use showed more inward deflection in the right posterior ventral accumbens. FWE-corrected p < 0.05. Saggital slice (left), Coronal slice (middle), Axial slice (right) (C) Significant negative association between times used marijuana and scalar values in the left hippocampus. Participants with greater number of lifetime uses showed more inward deflection in the anterior hippocampus cornu ammonius and the posterior hippocampus subiculum. FWE-corrected p < 0.05.
