Even though the Presidential election campaigns are drawing to a close, there is still time for the substance abuse prevention field to influence the election process by submitting questions to WebMD about substance abuse issues. WebMD is currently collecting questions that will be submitted to Tom Brokaw for possible inclusion in the October 7th debate between Senators John McCain (R-AZ) and Barack Obama (D-IL). To submit a question go to http://blogs.webmd.com/ask-the-candidates/2008/09/ask-presidential-candidates.html?ecd=wnl_nal_092908.
