can copenhagen dipping tobacco effect a breathalyzer to have a different reading?

Not Legal Advice: Yes, there have been cases in which chewing tobacco, specifically Copenhagen chewing tobacco, can possibly cause a false reading. If you are chewing tobacco prior to a breathalyzer test, it will invalidate the test. In fact, any foreign object in the mouth can render the test invalid.
