For instance, up until 2010, there was a 100:1 (one hundred to one) disparity between federal criminal penalties for crack cocaine possession vs. powder cocaine possession. Crack possession also carried a mandatory minimum five-year sentence. Obama signed the Fair Sentencing Act in 2010, reducing the disparity to 18:1 and removing the mandatory minimum. The law is still influenced by the incorrect belief that crack is more dangerous than powder, but the legal system is capable of recognizing and fixing its flaws (even if the fix is partial).
