Does Fair Sentencing Act of 2010, the problem or is the 18-to-1 disparity still racially discriminatory?

Under the Fair Sentencing Act of 2010, the disparity in amounts of crack and powder cocaine necessary to trigger a mandatory minimum sentence of five (or ten) years was reduced from 100-to-1 to 18-to-1. Does this “solve” the problem or is the 18-to-1 disparity still racially discriminatory?
