These association studies are near useless. Every positive behavior and positive outcome are correlated, and every bad behavior and outcome are correlated. Mothers who get high during their pregnancy are different from mothers who don't. A more informed one would be looking at women with seizures that are treated with cannabis and comparing them to women with the same disorder who aren't. There are still differences but they'd be smaller.
