Note that although almost all drugs (with the notable exception of crack) are used more frequently by whites than blacks according to anonymous surveys. See for example data here. But blacks are more likely to be arrested for drug offenses than whites.
I suspect a Simpson’s paradox here. To avoid this you would have to show that drugs are used more frequently by whites than by blacks of similar socioeconomic status. Otherwise, showing that whites use more drugs may just mean that whites can afford more drugs.
