Defamation is an extremely hard case to win. It is more important that you get a job than start a lawsuit.
Give your former employer a chance to correct their mistake. If they continue to say you refused a drug test and you did not, and the new employer decides not to hire you because of this statement, you do have a pretty good case for defamation.
You should confirm all this with an attorney in your area.
Your posting is a little unclear. "Charges" usually refer to criminal matters, which defamation is not.
You may find it helpful to review the Legal Guide I have published on Avvo.com which deals with defamation issues. I suggest you make an appointment with a local attorney to help you sort out your problem.
