How long does alcohol stay in your breath after drinking?

Long enough for your parents, teachers, probation officer etc to know.

Two days. Drinking liquid comet will remove the alcohol Oder for sure. Or you could eat a Tide Pod.

One hour for every drink that you have

In your breath?????

You metabolize approximately one drink per hour.

My mum says quite a long time she would imagine.

Until you brush your teeth

Once your breath stops smelling of alcohol, THEN you start excreting the alcohol-waste out of your pores, and that odor can last for 2-4 days.

Probably until you brush your teeth and your tongue or use mouth wash

Alcohol can be detected by a breathalyzer on the breath for up to 24 hours after the last drink.
