Note. Values are Pearson correlations (r). For cognition variables, higher scores reflect perceptions that DWH is less dangerous, the negative consequences less likely, and less acceptable to peers. Only non-zero values were used to calculate correlations for DWH and RWHD variables. Significant correlations (p < .001) are denoted in bold typeface. Gender was associated with marijuana use frequency at the .05 level, p =.025.
