Ethyl Alcohol, also known as drinking alcohol, ethanol, or simply alcohol, is one of the most widely used drugs in the world, and is legal in all but a handful of countries in the Middle East.
Despite its widespread use and social acceptance in most of the world, alcohol is considered by many experts to be one of the most harmful psychoactive drugs currently in use. Alcoholism affects over 200 million people worldwide and causes approximately 139,000 deaths annually worldwide, including up to 88,000 in the United States. In the United States, alcohol causes more deaths than any drug, other than tobacco.

Alcohol dependence is very common among heavy users. Unlike opioids such as heroin, withdrawal from alcohol has a significant risk of a fatal outcome. For severe alcoholism requiring inpatient care, benzodiazepines such as diazepam (Valium) and clonazepam (Klonopin) are often used, as they prevent GABA-related withdrawal symptoms and do not carry the risk of liver toxicity characteristic of alcohol. Diazepam is commonly prescribed in the United Kingdom, while clonazepam is more popular in the United States. Both benzodiazepines are characterized by long biological half-lifes.
For mild to moderate alcoholism, naltrexone is becoming increasingly accepted as an effective treatment for alcohol abuse, potentially far more effective than programs such as Alcoholics Anonymous.
Alcohol binge drinking can be particularly dangerous, as individuals often experience a positive feedback loop which can lead to further consumption. This is a contrast to marijuana, where consumption of large amounts usually leads to unpleasant effects.
The capture rate of alcohol is usually cited as being around 15%. This places it lower than cocaine (17%), heroin (23%), and tobacco (32%), but higher than cannabis (9%).
Alcohol has been ubiquitous throughout history in many civilizations. As a result, it has been used for a variety of medical purposes, in addition to recreation. The chief medical use of alcohol historically has been to reduce anxiety, although it has also been used (effective or not) as an analgesic, antipsychotic, antidepressant, and even anesthetic. These uses have been deprecated in modern times, but continue outside of formal medical environments, and in the developing world.
Alcohol has been demonstrated to have significant analgesic effects. A 1978 study found that ethanol at a dose of 0.75 mL / kg (about 2 standard drinks for a 75 kg person) had effects comparable to 0.2 mg / kg morphine (15 mg for a 75 kg person, equivalent to 150 mg codeine). It should be noted however that alcohol consumption may be dangerous when paired with certain injuries, such as concussions and internal bleeding. Alcohol has also been observed to worsen arthritis in many individuals. For reasons including these, acetaminophen, NSAIDS, codeine combination products, and cannabis are considered safer analgesics when medical care is not immediately available.
