Teens & Tobacco
Slide2Why teens use tobacco
Only a few decades ago, people smoked on airplanes, in movie theatres, in restaurants & at work
Today, people know a lot more about the dangers of tobacco, & it’s not as socially acceptable to smoke
Friends, family & the media greatly influence whether someone wants to start to smoke
Slide3Teens & Smoking
Influence of friends
Most people who become addicted start smoking in their teens
Teens with friends who use tobacco are more likely to also use
Influence of family
Studies show that children of smokers are more likely to smoke, even if their parents try to discourage them
Many children think that tobacco use is a behavior related to adulthood
Influence of media
Tobacco companies spend over $15 billion a year for advertising- prints, sponsoring events, bill boards, movies
Slide4Tobacco Products
Tobacco products are made from the dried, processed leaves of tobacco plants
Nicotine- a very addictive chemical in tobacco plants
In its pure form, nicotine is very poisonous; tobacco users are not poisoned because only small amounts are in a cigarette
Tobacco users take in nicotine by using cigarettes, cigars, pipes, or smokeless tobacco (chewing tobacco)
Slide5Chemicals in Tobacco Products
Nicotine is a stimulant
Stimulants are drugs that increase the activity of the nervous system
Once in the blood, nicotine reaches the brain within seconds
Slide6Nicotine
Major short-term effects of nicotine:
Increased heart rate; Increased blood pressure; Changes in brain which may lead to addiction
First-time tobacco users may experience mild signs of nicotine poisoning, which may include rapid pulse, clammy skin, nausea & dizziness
In frequent users, nicotine stimulates the part of the brain that produces feelings of reward & pleasure
Effects last for about 30 minutes
It is these feelings that make the continued use of tobacco seem appealing
Slide7Nicotine Addiction
People who use tobacco frequently begin to rely on it for feelings of alertness and pleasure
Ongoing use creates a tolerance, and with a increasing tolerance, users need more nicotine to produce the same effects on the mind & body
Tobacco use may become a habit to cope with stressful situations- a psychological dependence
Slide8Nicotine Withdrawal
If a nicotine addict goes for even a short period of time without nicotine, he or she may experience withdrawal
Withdrawal symptoms can begin in as little as 30 minutes after last dose of nicotine
Symptoms include:
Headaches
Irritability
Difficulty sleeping
Inability to concentrate
Intense nicotine cravings
Slide9Tar
The dark, sticky substance that forms when tobacco burns is known as tar
Tar is a mixture of hundreds of chemicals
Short term effects of tar:
Stains on fingers & teeth
Smelly hair & clothes
Bad breath
Increased number of respiratory infections
Impaired lung function
Slide10Carcinogens
Carcinogens are cancer-causing agents
Tar contains many chemicals that are known carcinogens
Tar can damage the respiratory system to the point that it can no longer function
Slide11Carbon Monoxide
When substances, including tobacco, are burned, an odorless, poisonous gas called carbon monoxide is produced
This carbon monoxide combines with red blood cells, and they are unable to carry oxygen as well as they should
Slide12Chewing Tobacco
Chewing tobacco contains many of the same chemicals as smoking tobacco
Chewing tobacco is as addictive as smoking cigarettes-
a user actually gets two times the amount of nicotine in a dose of chewing tobacco
Effects:
Stained teeth
Bad breath
Receding gums & tooth decay
Slide13Long-Term Risks
With every dose of tobacco, users increase their risk of developing respiratory diseases, cardiovascular disease, and several different forms of cancer.
Slide14Cancer
Lung Cancer
Is the leading cause of cancer death for both men & women
Estimated that 85% of all deaths by lung cancer are related to smoking
In most cases- by the time the cancer is recognized there are little treatment options available
Oral Cancer
Cancers of the mouth, tongue, & throat
About 90% of oral cancers occur in people who have used tobacco
Slide15Secondhand Smoke
Smoke that is inhaled by anyone around a smoker
Long-term exposure can cause cardiovascular disease, many respiratory problems, or cancer
Children exposed are more likely to develop asthma & allergies
Secondhand smoke can also cause long-lasting ear infections in children
Slide16Quitting!
The health benefits of quitting tobacco use begin immediately & continue throughout life
Immediately after quitting blood pressure lowers & heart rate returns to normal
People who quit feel increased confidence
Taste buds start to work again!
