Alcohol abuse, as described in the DSM-IV, is a psychiatric diagnosis describing the recurring use of alcoholic beverages despite its negative consequences. Alcohol abuse is sometimes referred to by the less specific term alcoholism. However, many definitions of alcoholism exist, and only some are compatible with alcohol abuse. There are two types of alcoholics: those who have anti social and pleasure-seeking tendencies, and those who are anxiety-ridden- people who are able to go without drinking for long periods of time but are unable to control themselves once they start. Binge drinking is another form of alcohol abuse. According to research done through international surveys, the heaviest drinkers happen to be the United Kingdom's adolescent generation.
When differentiating between alcohol abuse and alcoholism, one should remember that alcohol abuse is when the abuser has faced critical consequences for their actions, recently. Where an alcoholic has experienced a sense of withdrawal in the same time period.
Drinking culture refers to the customs and practices associated with the consumption of alcoholic beverages. Although alcoholic beverages and social attitudes toward drinking vary around the world, nearly every civilization has independently discovered the processes of brewing beer, fermenting wine, and distilling spirits.
Alcohol and its effects have been present in societies throughout history. Drinking is documented in the Hebrew and Christian Bibles, in the Qur'an, in art history, in Greek literature as old as Homer, and in Confucius’s Analects.
An alcoholic beverage is a drink that contains ethanol. Alcoholic beverages are divided into three general classes for taxation and regulation of production: beers, wines, and spirits (distilled beverages). They are legally consumed in most countries around the world. More than 100 countries have laws regulating their production, sale, and consumption. Beer is the third most popular drink in the world, after water and tea.
Alcoholic beverages have been consumed by humans since the Neolithic era; the earliest evidence of alcohol was discovered in Jiahu, dating from 7000–6600 BC. The production and consumption of alcohol occurs in most cultures of the world, from hunter-gatherer peoples to nation-states.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
Hospitality is the relationship between the guest and the host, or the act or practice of being hospitable. This includes the reception and entertainment of guests, visitors, or strangers.
