If a person slammed 1 shot of, say, Everclear… then IMMEDIATELY blew into a Breathalyzer, would the results be any different then if they had waited some time before blowing? What kind of brujeria is involved with these machines?Thank you

As you ingest alcohol beverages, the ethyl-alcohol metabolizes into your blood stream.

Ethanol is in the carbon dioxide exhaled from your lungs. A breathalyzer estimates your BAC based on the amount of ethanol it detects

The answer is yes. Part of the reason we ask “what time was your last drink?” is to control for residual mouth alcohol.

So yes, slamming ever clear can artificially inflate a BAC reading. Not from it being metabolized, but from residual strong traces in the mouth.

Hope that answers your question
