Washington ? Legislation approved by the Senate on Wednesday would significantly reduce the disparity in sentences handed out to those convicted of crack and powder cocaine charges.

Currently, a person convicted of crack cocaine possession gets the same mandatory jail time as someone with 100 times the same quantity of powder cocaine. That 100-1 ratio has been particularly hard on the black community, where convictions on federal crack laws are more prevalent.

Under the measure, approved by a voice vote, the ratio would be reduced to 18-1.

Sen. Dick Durbin, D-Ill., who worked out the legislation with Senate Judiciary Committee Republicans, said he had initially wanted a straight 1-to-1 ratio, but that the final product was a good bipartisan compromise.

“If this bill is enacted into law, it will immediately ensure that every year, thousands of people are treated more fairly in our criminal justice system,” he said.
