Look out! The latest research shows that you can get drunk even after drinking coffee.

A mixed drink of alcohol and coffee is a potentially deadly substance, first of all, when you are drunk and unaware of it.

General coffee energy drinks also have the risk of getting drunk, which can not be ignored. That's according to a study published in the journal Behavioral Neuroscience.

In several experimental studies, mice were more alert after drinking coffee, but there were also problems of unconsciousness after drinking alcohol, including the ability to avoid knowing that an accident might harm it.

Dr Thomas Gould of Temple University in Philadelphia, USA, said: "debunking the myth that coffee clears the brain is particularly important because drinking coffee mixed with alcohol can actually lead to misjudgment and lead to a tragic outcome.

"people who drink will only feel tired and drunk, and will still know that they are drunk.

Dr Gould and his colleagues studied the effects of alcohol, coffee and alcoholic coffee mixed drinks on rats' ability to overcome mazes and avoid aversion to stimuli.

The drinking mice were a little anxious, moved frequently, and had problems with avoiding the sense of aversion to stimuli.

Mice that drank up to six to eight cups of coffee with the same amount of coffee were more anxious, moved less, and were less aware of avoiding irritants.

In mice that drank both alcohol and coffee, alcohol prevented caffeine from causing anxiety in mice, but did not affect their consciousness. Therefore, alcohol suppresses the nervousness caused by coffee, animals are more relaxed and lack the ability to avoid threats.

For people, a mixture of alcohol and coffee will reduce their drunkenness and think they can engage in normal life activities, such as driving. In fact, they are powerless at this time.

However, "alcoholic mixed drinks are quickly gaining popularity among the public," Dr. Gould said.

He also said that these alcoholic and coffee drinks often reduce people's cognitive abilities and increase the chances of alcohol-related accidents, such as drunken driving, sexual crimes and other diseases.

He concluded: "all the indications are that there is a great risk of mixed drinking of alcohol and coffee, especially when staying up all night and persuading people to drink constantly. This is a basic principle."

The Food and Drug Administration of the United States is studying the safety of mixed drinks of alcohol and coffee and formulating relevant legal documents. Last month (November), the group sent notices to 30 manufacturers asking them to provide proof that the drinks were safe and in compliance with FDA laws.

So far, the US Food and Drug Administration has only approved caffeine as a soft drink additive with a concentration of less than 200/1000000, banning the addition of caffeine to any alcoholic beverage.

Under the Federal Food, Drug and Cosmetics Act, intentional addition of other substances such as caffeine to alcoholic beverages is illegal and unsafe. Unless approved by U. S. Food and Drug Administration documents for special occasions, or substances that are generally considered safe by the public.
