[Myth statement] ...eating breath mints. [Status] Busted [Notes] 
Adam's blood alcohol content only dropped slightly, by an amount that was in the testing machine's margin of error. The only way this is likely to help is by masking the scent of the alcohol in the hope that an officer will not carry out the sobriety test to begin with, and even then it is likely that an officer will already suspect a driver to be over the limit before actually speaking to them.
