ALCOHOL

ALCOPOPS

tried alcohol at least once.28% reported having an alcoholic beverage

drinking

What is Alcohol?• Depressant

• Contains intoxicating substance called ethyl alcohol or ethanol

• Slows down the functions of the brain and other parts of the nervous system

What is Alcohol?• Produced by a fermentation process

• Proof is the amount of alcohol in the substance (ex. 100 proof bottle of vodka is 50% alcohol)

• 12 oz. Beer = 4 oz. Wine = 1 oz. liquor

Results of fermentation

Effects of Alcohol

• Heart/Blood Vessels–Short term

•Perspiration increases and skin becomes flushed

–Long Term•High blood pressure and damage to the heart muscle; blood vessels harden and become less flexible

More Effects• Brain/Nervous System

–Short Term • Speech is slurred and difficulty walking

–Long Term • Brain cells are destroyed and unable to be replaced; damage to nerves in body resulting in numbness in hands and feet

…The Rest of Alcohol’s Effects• Liver

–Short Term •Liver changes alcohol into water and carbon dioxide

–Long Term •Liver is damaged possibly resulting in cirrhosis (scarring and destruction of the liver)

Healthy Liver

Alcoholic Liver

…The Rest of Alcohol’s Effects

• Stomach/Pancreas–Short Term

•Stomach acids increase, which often results in nausea and vomiting

–Long Term• Irritation occurs in the stomach lining, causing open sores called ulcers; pancreas becomes inflamed

Blood Alcohol Concentration

• Amount of alcohol in a person’s bloodstream

• legal limit is .08% for people 21 years old and older

• legal limit is zero for people under 21

Factors affecting the amount of alcohol in a person’s blood

• Gender

• Metabolism

• Amount of Alcohol (not # of drinks)

• How much they weigh

• How much time elapses after or between drinks

Drinking and Driving• 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

SAFEST AMOUNT OF

DRINKS = 0!!!

This is at any age!!!!

Testing for intoxication• Breath testers – include infrared light

absorptions devices and detect chemical reactions involving alcohol that produce electricity

• Breath test accuracy depends on capturing deep lung (alveolar) breath of subject

Testing for intoxication• Field sobriety tests – used by police to

estimate level of intoxication and determine if further testing justified

• Blood tests – Gas chromatography separates alcohol from the blood; levels are compared with standard reference samples

Consequences of teen DUI

• Harm to the driver and others• Severely restricted driving

privileges• Alcohol related injuries, property

damage, and death• Living with remorse

Alcohol Poisoning• Dangerous to just “sleep it off”• Signs

–Mental confusion, stupor, coma, inability to be excited, vomiting, and seizures

–Slow Respiration *Hypothermia *Dehydration *Irregular heartbeat

–CALL 911 immediately if suspicious of poisoning

are labeled clearly; 4 points each (12 points total)
