Gov. Bruce Rauner is signing legislation to ban the sale of synthetic drugs known as "bath salts" in Illinois.
Most states have passed laws to ban the chemicals, which mimic the effects of powerful drugs like cocaine.
The legislation Rauner says he will sign Monday at the courthouse in Taylorville would make selling bath salts a felony punishable with a fine of up to $150,000.
The Republican governor is signing the legislation on the same day the Republican National Convention starts in Cleveland, which he is skipping. Rauner said last week he is not attending because he is traveling the state signing bills that lawmakers passed this year.
