Drunkenness

Drunkenness means being intoxicated by alcohol. This means a person's brain and body are not working normally, because of the alcohol they have had. A person who is intoxicated is usually called drunk.
The effects of being drunk depend on how much alcohol a person has had to drink.
Effects
Alcohol causes the mind and body to not work normally.
In low amounts, alcohol often causes good feelings, reddened skin, and feeling relaxed. People who drink small amounts of alcohol may feel less nervous about being around others. Even in small amounts, alcohol slows down the brain. Alcohol interferes with normal brain communication and changes a person's behavior and mood. The ability to think clearly is often inhibited,. Consuming larger amounts of alcohol can drastically affect motor functions via its effects on the brain. Commonly seen effects on the brain and the rest of the central nervous system (CNS) include slurred speech and issues with coordination. It starts to affect a person's judgment - their ability to make good decisions. It also makes a person react more slowly and have slower reflexes. This is why it is not safe to drive even after drinking just a little.
In medium amounts, alcohol will cause trouble speaking clearly and moving the body normally. A person may have trouble staying balanced and walking normally. They may get confused or very tired. They will not be able to make good decisions. They may also start vomiting.
When a person drinks a dangerous amount of alcohol, they can get alcohol poisoning.
Alcohol poisoning
Alcohol poisoning is a medical emergency. "Alcohol poisoning" means that a person has drunk enough alcohol to cause a coma, dangerously slow breathing, or even death. A person with alcohol poisoning needs emergency medical treatment at a hospital to make sure they do not die from alcohol poisoning.
Signs and symptoms
Here are some of the signs and symptoms of alcohol poisoning:
Being very confused and almost unconscious
Going into a coma
Vomiting while in a coma. If this happens, the person can breathe the vomit into their lungs. This can burn and injure the lungs so badly that the person can die
Very slow breathing. If a person's breathing gets slow enough, the person can die
Very slow heart rate
Seizures
Low body temperature
If the person wakes up, they will not be able to remember what happened. This is called a "blackout."
First aid
When a person has alcohol poisoning, 9-1-1 or another local emergency telephone number should be called right away. First aid can help the person until an ambulance gets there.
A first aider SHOULD:
Lay the person down and try to keep them still
Turn the person on their side
Cover them with a blanket to keep them warm
If the person has a seizure, do not try to hold them still. Try to keep them from injuring themselves. Note that people having a seizure cannot control their movements, and their reflexes do not work.
If the person's heart stops, start cardiopulmonary resuscitation. An emergency medical dispatcher can explain how to do this
A first aider should NOT:
Leave the person alone
Give them anything to eat or drink
Give the person any medications or illegal drugs
Make them throw up
Put the person in a cold shower or bath
Make the person walk. Walking is not safe for a person with alcohol poisoning
Treatment
Paramedics and hospitals can treat alcohol poisoning by:
Putting a tube down the person's throat and pumping oxygen into their lungs (if they are not breathing well enough to survive)
Putting a tube down the person's nose and into their stomach to:
Pump alcohol out of the person's stomach
Pour activated charcoal into the person's stomach. This is a treatment for poisoning. The charcoal keeps more alcohol from being taken up into the bloodstream.
