Chemicals

• Cigarettes, alcohol and drugs contain harmful chemicals.

• Cigarettes have a chemical called nicotine. Nicotine is often put in bug sprays that kill insects. This cannot be good for us!

CIGARETTES!

What a Waste!

• It takes approximately 10 minutes to smoke a cigarette. So if you smoke a pack a day that is 3.3 hours you spend just on smoking cigarettes. Each cigarette cost about 25 cents each. Each cigarette cost 15 minutes of your life. If you pay $5.00 a pack for your cigarettes it will cost $150 a month and $1,800 a year.

Side Effects

With the help of Commercial Tobacco:• You will have less money. • You will become winded. • Your skin will wrinkle at an early age and

possibly look grayish. (Often smokers in their 40s look like non-smokers in their 60s).

• Your finger nails will be stained yellow. • Your clothes, hair and breathe will smell. • You may even get serious health problems like

lung cancer, heart disease or ulcers.

Smoking by Income

• Cigarettes are expensive, so why do you think that the less money people make, they more likely they are to smoke cigarettes? Does this make sense?

DRINKING

• Cigarettes aren’t the only things that can be bad for you…it is also dangerous to drink too much alcohol…

SAFETY

Accidents

• More than half of drownings and fatal falls are alcohol- or drug-related.

• 45% of emergency room visits are alcohol-related.

• 80% of patients in special units like burn centers have injuries related to alcohol use.

Drinking and Driving

Even small amounts of alcohol make driving unsafe. Drunk driving is not only unsafe, it's illegal. Even a blood alcohol level of .05% (below the legal limit for driving in most states) makes you twice as likely to have a car crash. Almost half of all fatal auto crashes are alcohol- or drug- related.

Drinking and Driving cont.

In 2004 in Oregon,

• 45% of fatal car crashes involved someone who had been drinking.

• 33% of the fatal crashes had someone over the .08% blood alcohol legal limit.

• Nearly 17,000 fatal car crashes in the U.S. in 2004 involved someone who had been drinking.

Sex: Pregnancy and STDs

• You are more likely to lower your morals or ignore safety precautions such as condoms if you are under the influence of alcohol or other drugs.

• Many unwanted pregnancies are due to irresponsible drinking.

• Many STDs are contracted when people are drinking too much.

Sexual Assault

• When you're intoxicated, impaired judgment can stop you from noticing dangerous situations and people. Slowed thinking and reaction time makes you more vulnerable to being forced into sexual activity. It also makes people less likely to notice when they are hurting others. Alcohol is involved in many acquaintance rapes.

HEALTH

Hangovers

• Headaches, nausea, vomiting, aches and pains all result from drinking too much. Drinking to the point of drunkenness makes you sick.

Weight Gain

• Alcohol is not water. A beer has about 150 "empty" calories that provide few if any nutrients.

• Many people who begin drinking heavily or regularly gain 10-20 pounds.

Cancer

• 2-4% of all cancer cases are related to alcohol. Upper digestive tract cancers are the most common, hitting the esophagus, mouth, larynx, and pharynx. Women who drink prior to menopause are more likely to develop breast cancer. Your risk of skin cancer doubles if you drink slightly more than "moderate levels." Some studies implicate alcohol in colon, stomach, pancreas and lung cancer. And let's not forget the liver...

Liver Problems

• Drinking too much alcohol damages the liver.

• The liver can only process about one alcoholic drink per hour.

• What happens when your liver is damaged?

•fatty liver •hepatitis•Cirrhosis•liver cancer

Alcohol Poisoning

• Drinking large amounts can result in alcohol poisoning, which causes unconsciousness and even death. Breathing slows, and the skin becomes cold and may look blue. Don't let a person in this condition "sleep it off."

Other Health Issues

• High blood pressure

• Depressed immune system

• Heart or respiratory failure…could mean death.
