Defining Addiction
� Physiological/Psychological Dependence
• Inextricably tied together
• Addiction traditionally based on four criteria:
1. Relief of withdrawal symptoms
2. Continued use despite harm to self and others
3. Unsuccessful efforts to cease using or cut down on use, including relapse
4. Tolerance

Defining Addiction
� Signs of Addiction
• Addictions are characterized by four common symptoms
1. Compulsion (can include obsession)
2. Loss of control
3. Negative consequences
4. Denial
• Process Addictions
• Behaviors known to be addictive because they are mood altering

Addictive Behaviors
� Compulsive or Pathological Gambling
• Cravings or highs similar to those experienced by drug users
• Often seek the excitement more than the money
• Incidence higher in men, lower-income individuals, those who are divorced, African Americans, older adults, those living within 50 miles of a casino, and college students
• 38 percent have cardiovascular problems
• Suicide rate 20 times higher than that of general population

Addictive Behaviors
� Compulsive Spending
• On average, compulsive spenders are $23,000 in debt.
• Compulsive spending often leads to compulsive borrowing to help support addiction.
� Symptoms that a spender has crossed the line into addiction include
• Buying more than one of the same item
• Keeping items in the closet with the tags still attached
• Repeatedly buying much more than the person needs or can afford
• Hiding purchases from relatives and loved ones
• Experiencing feelings of excitement when shopping

Addictive Behaviors
� Exercise Addiction
• About 2 million people with anorexia nervosa and bulimia nervosa use exercise to purge instead of, or in addition to, self-induced vomiting
• Try to meet needs for nurturance, intimacy, self-esteem, and self- competency that an object or activity cannot truly meet
• Men are increasingly abusing steroids and overexercising to attain an ideal frame
• Muscle dysmorphia (bigarexia) is a pathological preoccupation with being larger and more muscular
• Symptoms include excessive weight lifting, excessive exercising, and steroid or supplement abuse

Addictive Behaviors
� Technology Addictions
• Cell phones, video games, PDAs, networking sites, and the Internet can all be addictive.
• An estimated 5 to 10 percent of Internet users will likely experience Internet addiction.
• Symptoms include general disregard for one’s health, sleep deprivation, neglecting family and friends, lack of physical activity, euphoria when online, lower grades in school, and poor job performance.
• Compensation for feelings of loneliness, marital or work problems, a poor social life, or financial problems

Addiction Affects Family and Friends
� Codependence
• Pattern of behavior
• Person becomes “addicted to the addict”
• Disregard personal needs in order to meet needs or desires of addict
� Enabling
• Knowingly or unknowingly protects addict from consequences of behavior

Drug Dynamics
� Abuse often associated with illegal drugs, but many people abuse and misuse legal drugs
• Drug misuse—use for purpose not intended
• Drug abuse—excessive use
• Misuse and abuse may lead to addiction
• Drug and alcohol abuse contributes to more than 120,000 American deaths a year
• Costs $294 billion in preventable health care expenses annually.
• Although overall use of drugs in the United States has fallen by 50 percent in the past 20 years, the past 10 years have shown an increase in the use of certain drugs by adolescents.

Drug Dynamics
� How Drugs Affect the Brain
• Mesolimbic dopamine—neurons relay messages about pleasure
• Psychoactive drugs—affects chemical neurotransmission, either enhancing it, suppressing it, or interfering with it
• Some people’s bodies naturally produce insufficient quantities of neurotransmitters, which predisposes them to addictions such as alcohol, drugs, or exercise

Drug Dynamics
� Types of Drugs
• Prescription—more than 10,000 types sold in U.S
• Over-the-counter (OTC) drugs—no prescription needed
• Recreational—alcohol, tobacco, coffee, etc.
• Herbal preparations—products of plant origin
• Illicit (illegal)—all are psychoactive
• Commercial preparations—household cleaners, pesticides, etc.

Drug Dynamics
• Routes of Drug Administration
• Oral
• Injection
• Intravenous—into bloodstream
• Intramuscular—into muscle
• Subcutaneous—just under the skin
• Inhalation
• through the nose or mouth
• Inunction
• through the skin
• Suppositories
• through the vagina or anus
Copyright © 2011 Pearson Education, Inc.
Drug Dynamics
� Drug Interactions
• Polydrug Use
• Taking several substances simultaneously
• Synergism
• Effects are multiplied
• Expressed as 2 + 2 = 10
• Example: Alcohol and barbiturates
• Antagonism
• Work at same receptor
• Inhibition—the effects of one drug are eliminated or reduced by the presence of another drug
• Example: Alcohol and antibiotics
Copyright © 2011 Pearson Education, Inc.
Drug Dynamics
• Intolerance
• When drugs combine to produce extremely uncomfortable reactions
• Example: Antabuse and alcohol
• Cross-tolerance
• Tolerance for one drug creates a similar reaction to another drug
• Example: Alcohol and barbiturates
Copyright © 2011 Pearson Education, Inc.
Abuse of Over-the-Counter (OTC) Drugs
• Nonprescription medicine
• High doses can cause hallucinations, bizarre sleep patterns, mood changes, and sometimes death.
• Those most vulnerable to abusing OTC drugs are teenagers, young adults, and people over the age of 65.

Prescription Drug Abuse

• Prescription drug abuse is particularly common among teenagers.
• Abuse of opioids, narcotics, and pain relievers can result in life-threatening respiratory depression (reduced breathing).
• Abuse of depressants, including benzodiazepines, tranquilizers, barbiturates, and sedatives can result in seizures, respiratory depression, and decreased heart rate.
• Abuse of stimulants can cause elevated body temperature, irregular heart rate, cardiovascular system failure, and fatal seizures.

Prescription Drug Abuse
� College Students and Prescription Drug Abuse
• Increased dramatically over the past decade

Illicit Drugs
� Users of Illicit Drugs

• In 2006 51 percent of college students reported trying any drug; a third have smoked marijuana in the past year, and 20 percent have done so in the past month.
• For many students, their college environment coupled with our culture’s societal mores regarding substance use on college campuses may make substance use and abuse seem like the norm.
