Do you own the Smart Start company, or were you court ordered to use a Draeger device, and heard that Smart Start could be fooled?

Breathalyzer machines are often confused by other substances which throw off BAC estimations.

A breathalyzer machine tests for ethyl alcohol (ethanol) from alcoholic substances, and may misread many other substances in the human breath as alcohol content.

Here are some interesting examples.

Some breathalyzer machines become confused by acetone, which may be present in large amounts in diabetics and other people with special diets.

Breathalyzers have also been confused by fumes coming from certain paints, adhesives and paints.

In one dramatic example, a painter who was exposed to similar fumes but did not have any alcohol in his system registered a 0.075 BAC.

His true BAC was later determined to be 0.00.

BAC levels may be impacted by physical activity.

One study found that running up and down the stairs right before a breath test could decrease BAC by up to 25%.
