The effects of alcohol on the human body take several forms. Alcohol, specifically ethanol, is a potent psychoactive drug with a range of side effects. The amount and circumstances of consumption play a large part in determining the extent of intoxication, e.g. consuming alcohol after a heavy meal is less likely to produce visible signs of intoxication than consumption on an empty stomach. Hydration also plays a role, especially in determining the extent of hangovers. (O’Brien, 1999)
Alcohol has a biphasic effect on the body, which is to say that its effects change over time. Initially, alcohol generally produces feelings of relaxation and cheerfulness, but further consumption can lead to blurred vision and coordination problems. Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream it can diffuse into nearly every tissue of the body. After excessive drinking, unconsciousness can occur and extreme levels of consumption can lead to alcohol poisoning and death (a concentration in the blood stream of 0.55% will kill half the population). Death can also be caused by asphyxiation of vomit, a frequent result of overconsumption, blocks the trachea and the individual is too inebriated to respond. An appropriate first aid response to an unconscious, drunken person is to place them in the recovery position. (Forrest, 1997)
Intoxication frequently leads to a lowering of one's inhibitions, and intoxicated people will do things they would not do while sober, often ignoring social, moral, and legal considerations. The term intoxication is typically used in legal proceedings when some crime has been committed during a state of inebriation.
Intoxication
Ethanol acts as a central nervous system depressant. In small amounts, ethanol causes a mild euphoria and removes inhibitions, and in large doses it causes drunkenness, generally at a blood ethanol content of about 0.1%...................
