Diet mixers with alcohol increase drunkenness

In three separate sessions, US researchers breathalysed 16 participants after they drank vodka mixed with different combinations of diet and regular beverages. 

They found breath concentration of alcohol was 18% higher in individuals who used the diet soft drink.

The authors suggest the stomach may process sugar-sweetened drinks as food, delaying stomach emptying. 

Intoxication levels associated with diet mixers warranted greater consideration and consumers should be made aware of it, the authors wrote.
