Alcohol is a class of organic compounds containing hydroxyl (--OH) groups that are attached to a carbon atom. It is a psychoactive drug that has been used for centuries to make alcoholic drinks such as beer, wine and spirits.

Drinking too much alcohol can take a serious toll on you physically, mentally and emotionally. Learn how to recognize the warning signs and get support if you think you have a drinking problem or are concerned about a loved one.

It is a source of energy

Alcohol is a source of energy that can be found in alcoholic beverages (gin, vodka, whiskey, beer and wine). It is a two-carbon organic compound with a terminal hydroxyl group.

The hydroxyl group on the carbon atoms of an alcohol helps it penetrate biological membranes and can be distributed throughout the body. The small size and polar hydroxyl group on the carbon chain of an alcohol also make it soluble in water.

Alcohol has a higher energy per gram than carbohydrates and other macronutrients. This means that a large amount of the energy from an alcoholic beverage can be consumed immediately.

It is a drug

As a drug, alcohol affects the central nervous system and can cause a wide range of effects. It is a depressant which slows the brain's functions and can also interfere with judgment, behavior and reflexes.

This can make it difficult to think clearly and to act quickly, which is why you should drink in moderation. Heavy drinking can lead to health problems including liver damage, heart disease, and cancer.

It can also increase the risk of developing depression and violence. It can interfere with relationships and cause problems at home, work or school.

It is an addictive substance, which means that the body can develop a tolerance for it and have to drink more and more to achieve the same effect. As such, it is very difficult to break the habit of drinking if you do not seek help from a professional.

It is a tonic

Tonic water is one of the most popular mixers for alcoholic drinks. It’s known for its bitter flavor, derived from quinine. It can be mixed with many distilled spirits, including gin and vodka.

It’s also a great addition to fruit juices, especially lemonade. Tonic water adds fizziness and softens the harsh bitterness of a good fruit juice.

You can use it in nonalcoholic drinks as well, if you prefer. A long shot of espresso poured over a glass of tonic is a popular choice in coffee shops, or it works with cold brew coffee for an afternoon pick-me-up.

It’s also a great pairing with bitter spirits, such as Aperol and Campari. White port and tonic is another favorite, as is a refreshingly bright blood orange Gin and Tonic.

It is a poison

Alcohol is a poison because it affects the body in a way that is harmful to its cells. It can cause many unwanted effects, including vomiting and drowsiness, but it also has the potential to kill you if you consume too much in a short space of time.

Drinking too much can also harm your heart, liver, and lungs. It increases your risk of developing breast and some other types of cancer, and it can contribute to depression, violence, and relationship problems.

When drinking, it is important to pace yourself, and to eat foods that are high in protein and fats. This will help to slow down the absorption of alcohol into your bloodstream. It will also give your liver a chance to process the alcohol before it is released into your bloodstream.
