Tobacco Forms Cigarettes Smokeless tobacco Pipes and cigars The drug contained in tobacco is nicotine Nicotine is highly addictive
Harmful Substances in Tobacco carcinogen- a cancer-causing substance Selected Harmful Substances in Tobacco SubstanceHazard Arsenicpoisonous, carcinogen Benzopyrenecarcinogen Carbon Monoxidereduces oxygen capacity of blood Formaldehydecarcinogen Hydrogen Cyanidereduces the cilia function in lungs Nitrogen Dioxideirritates respiratory tract Nitrous Oxidereduces number of WBC in lungs PhenolCarcinogen Vinyl ChlorideCarcinogen
Harmful Substances in Tobacco The three substances in tobacco smoke which are especially harmful: 1. Nicotine 2. Carbon monoxide 3. Tar- thick liquid which coats the lungs Smokeless tobacco is not a safe alternative to smoking Contains many of the same chemicals and at least 28 different carcinogens
Diseases Associated with Tobacco Use Respiratory acute bronchitis pneumonia chronic bronchitis emphysema lung cancer tracheal cancer laryngeal cancer asthma Circulatory coronary heart disease stroke hypertension atherosclerosis heart attack
Diseases Associated with Tobacco Use Digestive mouth cancer throat cancer gum disease tooth loss liver cancer colon cancer acid reflux ulcers Endocrine pancreatic cancer diabetes
Diseases Associated with Tobacco Use Urinary bladder cancer kidney cancer Skeletal osteoporosis Reproductive infertility cervical cancer menstrual disorders low birth weight Sudden Infant Death Syndrome miscarriage ectopic pregnancy
Diseases Associated with Tobacco Use Other macular degeneration (blindness) cataracts vocal cord polyps chronic fatigue
Primary Diseases from Tobacco Use Heart Disease damages walls of arteries raises cholesterol levels increases blood pressure Emphysema destroys alveoli in the lungs Lung Cancer Mouth Cancer
Second-Hand/Sidestream Smoke second-hand smoke- air that has been contaminated by tobacco smoke sidestream smoke- smoke from the burning end of a cigarette Contains twice as much tar and nicotine as what the smoker inhales because it is not filtered Long-term exposure to second-hand smoke poses the same health risks as smoking
Tobacco Addiction addiction- a physical and/or psychological need for a drug or other substance Tobacco use typically leads to two types of dependence: physiological dependence- the body itself feels a direct need for a drug psychological dependence- the mind sends the body the message that it needs more of a substance
Physiological Dependence on Tobacco Nicotine increases the levels of a neurotransmitter involved in feelings of pleasure and reward (dopamine), making it highly addictive When tobacco users go a period of time without nicotine, they experience withdrawal withdrawal- unpleasant symptoms that occur when someone stops using an addictive substance anxiety, depression, irritability, fatigue
Psychological Dependence on Tobacco Tobacco use is often part of one’s habits, built into his or her daily routine Psychological dependence also results from false perceived effects of tobacco use: Provides energy Helps relax Controls weight “Benefits” are false, but if one believes that they are true, they reinforce the tobacco use
Reasons Teens Begin Using Tobacco 1. Attempt to appear sophisticated and mature 2. Peer pressure 3. Behavior modeled by others around them 4. Glorified in movies, TV, and advertisements 5. Rebellion Others?
Tobacco Advertising Tobacco is intensely marketed. Only the automobile industry markets more heavily. Kids and teens constitute the majority of new smokers—tobacco advertising is designed to appeal to them Emphasis on youthful vigor, sexual attraction, and themes of independence
Why is tobacco still legal? IT IS BIG BUSINESS!!!!! The tobacco industry spent $20,680,315 to lobby Congress in That amounts to a whopping $138,794 spent on lobbying for every day Congress was in session. That is on top of the $9,424,612 Big Tobacco gave in political contributions during the 2002 election cycle.
KEY FACTS Percent of high school students who smoke: 28% Percent of 8 th graders who smoke daily: 5.5% Approximately 90 percent of smokers begin smoking before the age of 21. Most people who smoke would like to quit Most people who begin smoking do not think that they will become addicted 1 in 5 U.S. deaths are attributable to smoking
The Bottom Line Not that many people are smoking. If you don’t start when you are young, you probably will not start. If you do start when you are young, you probably will become addicted.
Reasons Not to Smoke 1. You will be healthier and live longer 2. You won’t smell 3. You will save a great deal of money 4. You’ll keep your senses of smell and taste 5. You will have fewer allergies 6. You will not be confined to smoking areas 7. You will have more energy and stamina 8. You will have healthier skin 9. You will not hurt the health of others who have to breathe your smoke
Alcohol How alcohol affects the body: Alcohol slows neurotransmitter function, depressing the central nervous system Acts on : Spinal cord- slows reactions Cerebellum- alters balance, posture, and coordination Cerebrum- impairs senses and judgement
Factors in Individual Effects of Alcohol 1. Size and gender 2. Food in the stomach 3. How fast the person drinks 4. Other substances in the body 5. Tolerance- when the body becomes used to a drug, it takes more of the drug to produce the same effect
Short-Term Effects of Alcohol Blood-alcohol concentration (BAC)- amount of alcohol in the blood, expressed as a percentage Ohio’s legal limit: 0.1% 1. Euphoria (BAC=.03 to.12%) Become self confident and daring Attention span shortens Judgment becomes impaired Fine motor control diminishes
Short-Term Effects of Alcohol 2. Excitement (BAC=.09 to.25%) Become sleepy Trouble understanding or remembering things Reactions diminish Movements become uncoordinated Loose balance Blurred vision Senses diminish
Short-Term Effects of Alcohol 3. Confusion (BAC=.18% to.30%) Dizziness Highly emotional Sleepy Slurred speech Sensation of pain is reduced
Short-Term Effects of Alcohol 4. Stupor (BAC=.25% to.40%) Can barely move Cannot respond to stimuli May vomit May lapse in and out of consciousness 5. Coma (BAC=.35% to.50%) Unconscious Body temperature feels cool Slowed breathing and heart rate 6. Death (BAC above.50%)
Long-Term Effects of Alcohol Abuse Depressed immune system Heart disease Cirrhosis- scarring of the liver, impairing liver function Cancer (mouth, throat, esophagus, stomach, & liver) Kidney failure Hypertension Malnutrition Ulcers Impotence Bone Deterioration Personality Disorders (aggression, anxiety, depression) Alcoholism- disease marked by physical and psychological dependence on alcohol
Alcoholism 1 in 10 drinkers will become an alcoholic Youth who drink before the age of 15 are 4 times more likely to develop alcohol dependency than those who begin drinking at age 21.
Recognizing Alcoholism Drinking increasing amounts of alcohol and becoming drunk often Placing drinking ahead of other activities Drinking alone Experiencing blackouts and not remembering what he/she said or did Shows personality changes when drinking Making excuses for drinking, promising to quit (but doesn’t ), and/or refusing to admit how much he/she is drinking Treatment is possible—involves admitting problem, detoxification, and counseling
Alcohol and Crime More than 1 in 3 convicted offenders were drinking at the time of their offense. An estimated 50 to 75% of domestic violence cases involve alcohol. in 2006, 17,941 people were killed in alcohol- related crashes, representing 41% of all traffic fatalities. Over a third of all deaths among year- olds are alcohol related. NOTE: Minimum 6 month loss of license (even if no car is involved) and $500 fine for underage drinking
Drugs Drug- any nonfood substance taken into the body that can change the structure or function of the body or mind Drug use, misuse, and abuse: Use- drug is taken when needed, as directed, for the purpose intended Misuse- legal drug is used in a way that it is not intended Abuse- taking drugs that are illegal or not intended to be taken into the body
Drug Classifications (By Effect) stimulants- speed up the body’s functions amphetamines, cocaine, nicotine, methamphetamine depressants- slow down the body’s functions barbiturates, alcohol hallucinogens- distort moods, thoughts, and senses LSD, PCP narcotics- relieve pain and dull the senses morphine, codeine, oxyconton Highly addictive
Marijuana Dried leaves of the hemp plant, usually smoked Active ingredient is Tetrahydrocannabinol (THC) THC is able to bind to many receptors in the brain, resulting in a range of effects: Cerebellum- alters balance and coordination Cerebrum- weakens memory, alters sensory perception, results in erratic emotional responses
Effects of Marijuana Abuse Effects of the drug on the individual depend on: How much THC is in it User’s experience and expectations How it is taken Whether or not it is used with other drugs
Short-Term Effects of Marijuana Abuse Impaired memory Distorted perception Difficulty thinking and problem solving Loss of coordination Increased heart rate Anxiety Marijuana is an addictive drug Withdrawal from THC has been shown to be like that of cocaine, heroine, and alcohol
Long-Term Effects of Marijuana Abuse Cancer Marijuana contains some of the same, and sometimes even more cancer-causing chemicals found in tobacco Lung disease Marijuana contains the same irritants (tar, chemicals) as cigarettes Users develop coughing/wheezing and become more susceptible to colds and pneumonia Compromised immune function THC damages lymphocytes and lymphatic tissue, weakening the body’s ability to fight infectious disease
Long-Term Effects of Marijuana Abuse Amotivational syndrome Condition marked by chronic lethargy, lack of focus, and inability to concentrate Further drug use Marijuana is a “gateway drug” Studies show that few young people use other illegal drugs without first using marijuana Decreased testosterone levels in males THC is fat soluble, and it concentrates in tissues with high fat content. One of such areas is the testes. This inhibits testosterone production, possibly to the point where secondary female characteristics are observed
Why do young people abuse marijuana? Misconceptions of dangers Misunderstanding of health consequences Ignorance of possibilities of addiction and social disorders Influence of popular culture Marijuana has been a popular image tool Symbolizes an antisocial attitude
Inhalants Inhalants are a class of substances that are not drugs themselves, but have a drug effect when their vapors are inhaled Substances are common household products (ex.- cleaning products, aerosols) The drug effect of inhalants is a result of oxygen deprivation Chemicals and/or gasses displace oxygen in the blood, resulting in inadequate oxygen to the body, most notably to the brain
Short-Term Effects of Inhalant Abuse Nausea, vomiting/diarrhea Blurred vision Loss of coordination Headache Chest pain Runny or bloody nose Ringing in the ears
Inhalant Abuse Inhalants can be addictive Inhalants can kill at any time, even on the first use Asphyxia or suffocation Choking on vomit Sudden Sniffing Death Syndrome Instant death from inhaling toxins. Toxins interfere with the heart’s pace-making mechanism, producing cardiac arrest
Long-Term Effects of Inhalant Abuse Brain damage Toxins dissolve protective covering around neurons Damage to peripheral nerves Numbness, tingling, paralysis Lung damage Liver damage Kidney stones Toxins interfere with kidney’s ability to control blood pH Leukemia Muscle atrophy
Steroids Chemicals similar to the male sex hormone testosterone Anabolic- builds tissue Anabolic steroids can grow muscle at an increased rate Steroids enter the body’s cells and cause them to increase protein production Taken in pill form or injected
Consequences of Steroid Abuse For adolescents: Halted growth due to premature skeletal maturation For males: Shrinking of the testicles Development of breasts Baldness Infertility For females: Growth of facial hair Deepening of the voice changes in or cessation of the menstrual cycle
Long-Term Effects of Steroid Abuse Stroke Enlarged heart muscle & high blood pressure Liver cancer Kidney disease “Roid Rage”- uncontrollable aggressive outbursts brought on by steroid use Psychological disorders (depression, inappropriate anger)
Cocaine Stimulant powder made from the leaves of the coca plant. Snorted, smoked, or injected Crack cocaine- a concentrated form which is smoked Increases the activity of a neurotransmitter in the brain responsible for feelings of pleasure (dopamine) Results in a relatively brief high, often followed by a “crash” characterized by depression and withdrawal
Short-Term Effects of Cocaine Abuse Increased respiration, heart rate, and blood pressure Because of effects on the heart, it can kill at any time, even the first use Disturbances in heart rhythm Irritability Headache/Dizziness Insomnia
Long-Term Effects of Cocaine Abuse Heart attack Stroke Respiratory failure Erosion of nasal septum Memory loss
Ecstasy (MDMA) “Club drug” in tablet form Causes the release of a neurotransmitter which affects mood, sleep, and heart rate Over-stimulation of these receptors can damage them Has a synergistic effect with alcohol Dangerously boosts the effects of both substances when used together Identified as a gateway drug
Short-Term Effects of Ecstasy Hallucinations Muscle tension Tremors Blurred vision Hyperthermia Can lead to organ failure and death Can kill at any time, even the first use
Long-Term Effects of Ecstasy Nerve cell damage Psychiatric disturbances Anxiety, panic attacks, depression, mood swings Cognitive impairment Memory loss
Risks of Substance Abuse Physical Risks Chronic disease and organ damage Decreased energy and endurance Weakened immune system Injury
Risks of Substance Abuse Mental/Emotional Risks ADDICTION Depression Inability to concentrate Reduced ambition Unstable mood
Risks of Substance Abuse Social Risks Social withdrawal Stress on family and friends Poor performance at work/school Trouble with the law
Influences 1. Boundary Makers vs. Boundary Breakers A line (boundary) is crossed when a person accepts negative consequences with a choice Two groups influence decisions with regard to this line Boundary makers- recognize the value of having lines in place and influence you to stay within them Boundary breakers- disregard the value of having lines and have crossed them so many times that the lines don’t exist Once the line is crossed, it is much easier to cross it again and again
Boundaries No Boundaries
What are the long-term results of having no boundaries and consequently no direction? KEY POINT: One is more apt to accept negative consequences when pressured to do so by a boundary breaker
Influences 2. Voids Void- an unfulfilled part of one’s life Voids may center on love, acceptance, occupation, and/or relationship to goals Voids are very powerful, and people actively seek to fill them Voids may be filled by positive or negative activities Examples? KEY POINT: when a negative action fills a void, negative consequences are disregarded
Influences 1. Media Drug messages heavily center on youth and fun creates associations with these images and disassociates the products with their negative effects Themes are very appealing to young people: Attraction Fun Sophisticated/Cool image Humor
Addiction Addiction- physical and/or psychological need for a drug or other substance Signs of addiction: Using drugs on a regular basis Lying about the amount/frequency of use Thinking that drugs are necessary to have fun Avoiding other people in order to use drugs Giving up activities that the person used to enjoy Pressuring others to use drugs Frequent moods of depression and hopelessness Regularly missing school or work
4 Stages of Addiction 1. Reinforcement- User has all desired results with few or no consequences. The belief is that use is fun and rewarding and cannot cause harm. Feeling Normal
4 Stages of Addiction 2. Tolerance- The body becomes used to the drug and needs greater amounts to get the desired effect.
4 Stages of Addiction 3. Dependency- Psychological belief that that the individual needs the drug to be normal. Signs of withdrawal begin to show.
4 Stages of Addiction 4. Addiction- Individual physically and psychologically needs drug to feel normal. Severe withdrawal becomes progressively worse.
Rule of 5 to 15 If someone begins using a substance after the age of 18, he or she can develop an addiction within 5 to 15 years If someone begins using a substance between the ages of 13 and 17, he or she can develop an addiction within 5 to 15 months If someone begins using a substance before the age of 13, he or she can develop an addiction within 5 to 15 weeks
Refusal Skills Saying “no” effectively ay no in a firm voice ell why not ffer another idea romptly leave
Tips for Assertive Refusal Use humor to break tension Use “I” statements—don’t accuse or blame the person Take your time—collect your thoughts Stand up straight and maintain eye contact Speak in a firm but polite voice Don’t apologize for saying no Walk away from the situation
Refusal Skills Scenarios group #1 A group of friends is trying to convince you to go into town to buy some pot. group #2 One of your older sibling’s friends wants you to have a cigarette with him/her. group #3 At a party, your friends are drinking beer. They have invited you to join them. group #4 You and your friends are offered ecstasy at a party. It appears that your friends are going to accept it.
Refusal Skills Scenarios group #5 You are hanging out at a friend’s house, and everybody is bored. Somebody suggests that it would be fun to “huff” the vapors from a cleanser in the garage. group #6 You are working out at the gym. Somebody with great muscle definition tells you that you could get stronger a lot easier if you just take the steroids that he/she offers you. group #7 While studying late for final exams, a friend of your older sibling tells you that the pills he/she has will wake you up and keep you alert, and that he/she will give you some for free.
