The last column shows that study members with more persistent cannabis use showed greater IQ decline from childhood to adulthood.
↵*This coefficient indicates change in IQ from childhood to adulthood, with negative values indicating decreases in IQ. These change scores are in SD units, with values of 0.20, 0.50, and 0.80 reflecting small, medium, and large changes, respectively.
