Study Reveals Diet Drinks Affect Breath Alcohol Level

Mixing alcohol with your favorite diet drink could affect your breath alcohol level. What does this mean? If you are the subject of a breathalyzer test, chances are your diet drink is going to cause you to blow a higher level than if you drank alcohol with a regular soda.

In a new study performed by the Drug and Alcohol Dependence journal, 10 women and 10 men aged 21 to 30 years old were given 5 various mixed drinks over 5 different sessions: 0.91 ml/kg vodka + 3.64 ml/kg of diet soda, 0.91 ml/kg vodka + 3.64 of regular soda, 1.82 ml/kg vodka + 7.28 ml/kg diet soda, 1.82 ml/kg vodka + 7.28 ml/kg regular soda, and 1 placebo beverage. Researchers measured the subjects’ breath alcohol levels repeatedly throughout each session, up to 180 minutes after consumption.

The results showed that the participants that were given diet soda drinks with a low-alcohol level had a 22 percent higher breath alcohol content (BrAC) than those that were given drinks mixed with regular soda. Furthermore, those subjects that were given high-level alcohol drinks showed a 25 percent higher BrAC when those drinks were mixed with diet soda. The study did not show a difference in how the drinks affected the different sexes.

Generally speaking, alcohol levels are often also increased or decreased by the intake of food as alcoholic drinks are consumed. This, along with moderation, and the type of mixer used should be factors to consider if you plan on consuming an alcoholic drink before getting into a situation that may result in a breathalyzer test.
