Vodka with Red Bull 'deadly cocktail' for health disaster

A new study suggests that mixing alcohol with energy drinks such as Red Bull could be even worse for your heart and nervous system than it was previously thought.

Research has linked high-caffeine cocktails with heart problems and anxiety, and a top brain expert fears the drinks could be a health disaster, the Daily Star reported.

Professor Peter Miller, from Deakin University in Victoria, Australia, said that most research has only looked at the effects of one shot and one energy drink.

That ignores the fact that many party-goers knock back several in a night.

People who have energy drinks tend to stay out longer and so get through more alcohol, studies revealed.

Others found those who neck them are more likely to drink-drive, get in a fight or injure themselves while drunk.
