Phenotypic correlations between the 5 cannabis-related experiences ranged from 0.51 (between hallucinations and depression/anhedonia) to 0.84 (between cognitive difficulties and depression/anhedonia; supplementary figure 1) in COGA. Correlations were slightly lower in the CATS replication sample (0.37–0.64; supplementary figure 1).
