Just one shot of whisky makes people dangerous

A team of international researchers has found that a single alcoholic drink makes a person more likely to harm humans or animals - or act "impurely" by relishing behaving badly. 

An author of the study - which involved 329 people between the ages of 18 to 52 - said: "Drunk people want to do more immoral things than sober people.

"But we only observed it for two types of behaviours: related to harming others and related to so-called purity violations."

The scientists looked at their subjects when they were tipsy and sober and asked them questions about five categories: care, fairness, loyalty, authority and purity. 

Lead author Mariola Paruzel-Czachura, an associate professor at the University of Silesia in Katowice, Poland, said: "Alcohol has been with us for centuries. It is commonly used in many cultures, but surprisingly, there is little research to understand how it impacts human morality."
