Depressant Contains an intoxicating substance called ethyl alcohol or ethanol Produced by the fermentation process ◦ The anaerobic (no oxygen) conversion of sugar to carbon dioxide and alcohol by yeast.
The concentration of alcohol in a beverage is the proof value Proof value = 2X percentage alcohol. Example: 100 proof (whiskey) contains 50% alcohol
12 oz beer 5 oz wine Mixed drink with 1.5 oz of 80 proof liquor (40% alcohol) Current recommendations are: – 1 drink/day for women – 2 drinks/day for men
1/3 are abstainers 2/3 are drinkers – 1/3 are light drinkers – 1/3 are moderate/heavy drinkers 10% of the drinking population is considered heavy drinkers- they are responsible for 50% of all alcohol consumption in the US! Annual Sales of alcohol average out to roughly 2.3 gallons of absolute alcohol per person!
20% rapidly absorbed into bloodstream 75 % through upper part of the small intestine and the rest enters further along in the intestinal tract. Metabolism of alcohol is in the liver. 2-10% is not metabolized but is excreted through the sweat glands, lungs and kidneys.
Strength of the beverage Number of drinks consumed Speed of consumption Presence of food in stomach Physical tolerance
Percentage of alcohol in a measured amount of blood Measured from exhaled breath or blood sample
Drinking alcohol impairs vision, reaction time, and coordination. DWI and DUI –leading cause of death among teens Signs of intoxication can begin to appear as low as 0.02 There is no acceptable BAC level for anyone under 21
Fetus is exposed to alcohol in a slower manner than an adult Damage results in mental retardation Other characteristics are low birth weight, facial abnormalities, widely spaced eyes, and a much smaller head Full expression rate: 1-3 out of 1000 births Partial expression rate: 3-9/100 births
Regular daily intake of large amounts Regular heavy drinking limited to weekends Long periods of sobriety interspersed with periods of binge drinking lasting weeks or months Heavy drinking limited to periods of stress
