• Wine - 12-14% is alcohol is fermented from grapes or other fruits.

• Liquor - 40-50% is alcohol is distilled made from grains, fruits, rice or vegetables.

• A drink’s “proof” is twice as high as its actual alcohol content. So a 80-proof liquor is really composed of 40% alcohol.



Comparing types of Alcohol

• Beer - 12 ounces

• Wine - 5 ounces

• Hard liquor (a shot) - 1 1/2 ounces

Alcohol and digestion• The body does not digest alcohol like food.• The liver can only metabolize 1/2 ounce of

pure alcohol per hour, which is turned into water. Scar tissue that damages the liver is called cirrhosis.

• 20% of alcohol enters the bloodstream through the walls of the stomach.

• Alcohol is high in calories and has no nutritional value. • 4,000 people die each year as a result of

alcohol poisoning, drinking too fast and/or too much.

• Social drinking in moderation can provide health benefits.

Blackouts are periods of time that the drinker cannot recall.

Hangover is the term for physical symptoms such as nausea, headache and sensitivity to light from drinking too much alcohol.



Blood alcohol concentration

Is the amount of ethanol alcohol in a person' s blood is expressed by a percentage. BAC measures the number of milligrams of ethanol per 100 milliliters of blood A BAC of 0.1 percent means that 1/10 of 1 percent of the fluid in the blood is ethanol.

YOU ARE LEGALLY DRUNK IN

NEW JERSEY WITH A .08% BAC.



Factors that affect a person's Blood Alcohol Concentration

• Gender • Age• Amount of food in eaten• Amount of alcohol consumed• Body weight and/or percent body fat• Speed at which alcohol is consumed• Presence of other drugs in the bloodstream

• Of all fatal car accidents, about 50% involve alcohol.



ALCOHOL AND DECISIONS• Only time without drinking can sober a person up.• The greatest number of people arrested for DWI

were drinking beer.• Alcohol does depresses the central nervous system,

but all people do not react the same way, some get violent, some funny but all will have a slower reaction time, reduced coordination, loss of common sense and take more risks.





Marijuana

•It can be classified as a

depressant, stimulant or

hallucinogenic drug, it depends on the amount of THC (the main ingredient which is very powerful, the more THC the more a person will hallucinate). •The average amount of THC is normally 3 %, the active ingredients of the leaves; stems and flowers pass through the lungs when smoked.



Marijuana Facts• Derived from the hemp plant.• THC is absorbed in fatty tissues in the body.• Traces can be found for weeks in urine tests.• When smoked produce over 400 chemicals.• All forms are mind-altering.• Smoking affects the brain which reduced

coordination, alertness, and reaction time.• Mixed with cigars it is called a blunt.• Cannabis is referred to marijuana and other drugs

from the hemp plant.• Yes, it does contain cancer causing toxins, over 400

different chemicals.



Marijuana- The most widely abused illegal drug in the world.

• Short term or immediate effects include impaired short-term memory, attention, slowed reaction time, judgment,coordination, balance, increased heart rate, bloodshot eyes. The user may feel thirsty and hungry when using pot.

• Long-term effects can lead to addiction, paranoia, anxiety, learning and memory difficulties as well as a weakened respiratory and immune system.



Stimulants - Are drugs that speed up activities of the central nervous system. These drugs increase heart rate, blood pressure, and breathing rate and constrict pupils of the user.

Hallucinogens - Are drugs that altar perception, thought and mood. They have no medical uses. The user often sees colorful visions and feel like they have superhuman powers.





Inhalants

•Any household product (glue, hair spray, cleaning fluids, paint thinner, gasoline) that is inhaled through the nose that produces a desired effect. •Inhalant users are also at risk for Sudden Sniffing Death (SSD), which can occur when the inhaled fumes take the place of oxygen in the lungs and central nervous system. •This basically causes the inhalant user to suffocate. Nosebleeds, nausea, slurred speech, headaches, loss of smell and brain damage are some common side effects.



ALL DRUGS

• Because of their strength and potential

for harm the FDA has put labels on prescription medicines, over-the-counter medicines and alcohol products that operating a motor vehicle may cause harm to you and others.

• Always drive with a clear head and sound body. Do don’t drive after taking any type of drugs.
