Alcohol intoxication, also known in overdose as alcohol poisoning, commonly described as drunkenness or inebriation, is the behavior and physical effects caused by a recent consumption of alcohol. In addition to the toxicity of ethanol, the main psychoactive component of alcoholic beverages, other physiological symptoms may arise from the activity of acetaldehyde, a metabolite of alcohol. These effects may not arise until hours after ingestion and may contribute to the condition colloquially known as a hangover. The term intoxication is commonly used when large amount of alcohol is consumed along with physical symptoms and deleterious health effects.
Ethanol is an organic compound with the chemical formula CH3CH2OH. It is an alcohol, with its formula also written as C2H5OH, C2H6O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, and the active ingredient in alcoholic drinks.
Denatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom; and denatured rectified spirit is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; and denatonium makes it bitter.
Rubbing alcohol is either an isopropyl alcohol or an ethanol-based liquid, with isopropyl alcohol products being the most widely available. The comparable British Pharmacopoeia (BP) is surgical spirit. Rubbing alcohol is denatured and undrinkable even if it is ethanol-based, due to the bitterants added.
A tincture is typically an extract of plant or animal material dissolved in ethanol. Solvent concentrations of 25–60% are common, but may run as high as 90%. In chemistry, a tincture is a solution that has ethanol as its solvent. In herbal medicine, alcoholic tinctures are made with various ethanol concentrations, which should be at least 20% alcohol for preservation purposes.
Fusel alcohols or fuselol, also sometimes called fusel oils in Europe, are mixtures of several higher alcohols produced as a by-product of alcoholic fermentation. The word Fusel is German for "bad liquor".
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish where it provides energy when oxygen is scarce.
Liquor is an alcoholic drink produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation. Other terms for liquor include: spirit, distilled beverage, booze, spirituous liquor or hard liquor. The distillation process concentrates the liquid to increase its alcohol by volume. As liquors contain significantly more alcohol (ethanol) than other alcoholic drinks, they are considered "harder." In North America, the term hard liquor is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term spirits is more commonly used in the UK. Some examples of liquors include vodka, rum, gin, and tequila. Liquors are often aged in barrels, such as for the production of brandy and whiskey, or are infused with flavorings to form flavored liquors, such as absinthe.
Kilju is the Finnish word for home made alcoholic beverage typically made of sugar, yeast, and water.
Rectified spirit, also known as neutral spirits, rectified alcohol or ethyl alcohol of agricultural origin, is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. In some countries, denatured alcohol or denatured rectified spirit may commonly be available as "rectified spirit", because in some countries the retail sale of rectified alcohol in its non-denatured form is prohibited.
Alcohol is any organic compound in which a hydroxyl functional group (-OH) is bound to a carbon atom, usually connected to other carbon or hydrogen atoms. An important class are the simple acyclic alcohols, the general formula for which is CnH2n+1OH. Of those, ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages, and in common speech the word alcohol refers specifically to ethanol. Articles related to alcohol include:
An alcohol-free or non-alcoholic drink, also known as a temperance drink, is a version of an alcoholic drink made without alcohol, or with the alcohol removed or reduced to almost zero. These may take the form of a non-alcoholic mixed drink or non-alcoholic beer, and are widely available where alcoholic drinks are sold.
Recommendations for consumption of the drug alcohol vary from recommendations to be alcohol-free to daily or weekly drinking "safe limits" or maximum intakes. Many governmental agencies and organizations have issued guidelines. These recommendations concerning maximum intake are distinct from any legal restrictions, for example countries with drunk driving laws or countries that have prohibited alcohol. To varying degrees, these recommendations are also distinct from the scientific evidence, such as the short-term effects of alcohol consumption and long-term effects of alcohol consumption.
An alcohol enema, also known colloquially as butt-chugging or boofing, is the act of introducing alcohol into the rectum and colon via the anus, i.e., as an enema. This method of alcohol consumption can be dangerous and even deadly because it leads to faster intoxication than drinking since the alcohol is absorbed directly into the bloodstream and bypasses the body's ability to reject the toxin by vomiting.
The German laws regulating alcohol use and sale are mostly focused on youth protection. In contrast to many other countries, legislation is relatively lenient and not designed to keep young people away from alcohol, but rather intended to teach them an appropriate approach to alcohol consumption, which is reflected by one of the lowest drinking ages in the world.
Surrogate alcohol is a term for any substance containing ethanol that is intentionally consumed by humans but is not meant for human consumption. Some definitions of the term also extend to illegally produced alcoholic beverages.
An alcoholic beverage is a drink that contains ethanol, a type of alcohol and is produced by fermentation of grains, fruits, or other sources of sugar. The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Alcoholic drinks are typically divided into three classes—beers, wines, and spirits—and typically their alcohol content is between 3% and 50%.
Alcohol, sometimes referred to by the chemical name ethanol, is a depressant drug found in fermented beverages such as beer, wine, and distilled spirit -- in particular, rectified spirit. Ethanol is colloquially refereed to as "alcohol" because it is the most prelavent alchol in alcholic beveraged, but technically all alcoholic beverages contain several types of psychoactive alcohols, that are categorized as primary, secondary, or tertiary; Primary alcohols are oxidized to aldehydes, secondary alcohols undergo oxidation to form ketones, while tertiary alcohols are generally resistant to oxidation; Ethanol is a primary alcohol that has unpleasant actions in the body, many of which are mediated by its toxic metabolite acetaldehyde. Less prevalent alcohols found in alcoholic beverages, are secondary, and tertiary alcohols. For example, the tertiary alcohol 2M2B which is up to 50 times more potent than ethanol and found in trace quantities in alcoholic beverages, has been synthesized and used as a designer drug. Alcoholic beverages are sometimes laced with toxic alcohols, such as methanol and isopropyl alcohol. A mild, brief exposure to isopropyl alcohol is unlikely to cause any serious harm, but many methanol poisoning incidents have occurred through history, since methanol is lethal even in small quantities, as little as 10–15 milliliters. Ethanol is used to treat methanol and ethylene glycol toxicity.
Alcohol-induced respiratory reactions, also termed alcohol-induced asthma and alcohol-induced respiratory symptoms, are increasingly recognized as a pathological bronchoconstriction response to the consumption of alcohol that afflicts many people with a "classical" form of asthma, the airway constriction disease evoked by the inhalation of allergens. Alcohol-induced respiratory reactions reflect the operation of different and often racially related mechanisms that differ from those of classical, allergen-induced asthma.
