In fact, there are people who have faced serious legal problems when police accuse them of drunk driving and they did not consume alcohol.
As surprising as it may seem, other things can cause your breath to register as alcohol if you take a Breathalyzer test.

If this happens, you can reasonably assume that you are going to face several legal challenges in your near future.
