A drug is a pleasure producing chemical. Drugs activate or imitate chemical pathways in the brain associated with feelings of well-being, pleasure and euphoria. Neuroadaptation, Tolerance, and Withdrawal • Neuroadaptation: The brain’s response to over stimulation from drugs. In direct response to overstimulation, the brain regions decrease in sensitivity and become unresponsive (deaf) to normal levels of stimulation. • Tolerance: The process by which the reward and pleasure centers of the brain adapt to high concentrations of pleasure neurotransmitters. • Withdrawal Symptoms: The mirror image of the drug effects will always appear when a tolerant user tries to stop use. Cessation of drug use leads to ‘inversion of the high’. • Under unstimulated conditions (without drugs) there is profound interference with the ability to experience normal pleasure. When sober, the user feels anhedonia, anxiety, anger, frustration and craving. The pleasure system remains impaired for months to years, interfering with sobriety, learning, and impulse inhibition. • In addition to pleasure circuits each drug type affects other neurotransmitter circuits. These brain pathways overstimulated by drugs also neuroadapt and become under active, leading to anxiety, depression, and loss of energy. Definition of Addiction • Compulsion: loss of control The user can’t not do it s/he is compelled to use. Compulsion is not rational and is not planned. • Continued use despite adverse consequences An addict is a person who uses even though s/he knows it is causing problems. Addiction is staged based on adverse consequences. • Craving: daily symptom of the disease The user experiences intense psychological preoccupation with getting and using the drug. Craving is dysphoric, agitating and it feels very bad. • Denial/hypofrontality: distortion of cognition caused by craving Under the pressure of intense craving, the user is temporarily blinded to the risks and consequences of using. Model for nicotine addiction cycle during daily cigarette smoking C I M Model Treatment Causes of Craving E W M S • Environmental cues (Triggers) immediate, catastrophic, overwhelming craving stimulated by people, places, things associated with prior drug-use experiences • Drug Withdrawal inadequately treated or untreated • Mental illness symptoms inadequately treated or untreated • Stress equals craving Environmental Cueing = Conditioned Craving Drug pleasure becomes associated with specific people, places, and things; to encounter any of those things in the environment is to trigger craving for the drug. Such triggers persist for decades after use. Abuse versus Addiction • Substance Abuse is distinguished from Addiction by the appearance of tolerance and withdrawal, leading to loss of control over use. • Substance Abusers require motivation to stop. • Addicts require treatment to stop.

Apply B P S M (bio-psycho-social model) to yourself: • • • • • • • Family history of addiction? Do you have a tendency to boredom or ADHD? Are you anxious or depressed? Have you suffered sexual trauma? Do you use substances to reduce stress? Did drug and alcohol use enter your life at a difficult time? Are you surrounded by drug and alcohol users? Bio-Psycho-Social Model Are you in trouble? How can you tell if you are getting into trouble? • Are you using more frequently and using greater amounts? • Have you developed tolerance? • Is your use causing adverse consequences: grades, friends, money, health, unwanted sexual behavior? • Do you crave the drug under addiction conditions: Environment, Withdrawal, Mental Health, Stress (EWMS) • If so, when you crave the drug, can you talk yourself into using it, even when you have resolved to not use? • When you have resolved not to use, under known craving conditions, do you find yourself using: environmental cues, anxiety or blue, withdrawal (bored, irritable, sleep), or when you are stressed? Bio-Psycho-Social Model Are You an Addict? TRY THE “EXPERIMENT” • Resolve not to use. • Go about your usual daily activities. • Put yourself around the drug and people using it. • Each day, score how high or low your craving to use has been for that day. C I M Model Treatment Questions about Craving 1. What is your craving score? 2. Why is your craving score high? or low? 3. How are you going to manage the craving? 4. How are you going to manage the craving for the rest of the day? Bio-Psycho-Social Model Are You an Addict? • Were you able to not use? • Did you find your mind talking you into using? • Did you struggle not to use? • Were you able to have pleasure without using? • Did you have problems with boredom, depression or anxiety? Bio-Psycho-Social Model What to do • Get out of the using environment. • Find alternative sources of pleasure. • Work on balancing stress. • Seek help for mental health issues and other personal stresses. Addiction: Risk & Resilience • • • • • • • • • • • • • • Inherited predisposition (genetics) Childhood trauma or abuse Unwanted sexual involvement before age 13 Mental Illness: depression, anxiety, personality disorder Attention Deficit Disorder (ADD) Learning disabilities/school failure Subjected to teasing, bullying Acne and/or obesity Other than heterosexual orientation Social rejection Early sexual involvement Onset of drug use before age 16 Enabling environment Ignorance • • • • • • • • • • • • • • • No family history of addiction Good mental health Academic competence Positive relationship with an adult Family eats dinner together 5 days/wk Peer group participation (clubs) Participation in sports Participation in music, drama or dance Involvement in faith-based activities Taking care of pets Volunteer activities Social acceptance Environment disapproves of drug use Immediate, appropriate scaled consequences for alcohol/drug use. Early intervention for alcohol/drug use END SEGMENT TWO Overview Bio-Psycho-Social factors Genetics: Does alcoholism or drug addiction run in your family? Were you truly bored in school? Were you hyperactive? Can you hold your liquor better than others? Childhood Abuse: Did you suffer trauma (physical or sexual abuse) during your childhood? Did you experience any other life-changing difficulties? Mental Illness: Do you have a parent or grandparent who is has a mental illness: depression, anxiety, bipolar disorder or schizophrenia?

Enabling System: How easy was it for you to get alcohol/drugs? Did your parents and peers approve or disapprove of your use? Bio-Psycho-Social Model Assessment Goal: Develop an assessment of risk for becoming addicted 1. Develop a family tree, noting all inherited diseases, school failure, mental illnesses, and protective factors 2. Are symptoms of the addiction present in family or individual? 3. If you are concerned, screen Mental Health using Beck Depression Inventory and Beck Anxiety Inventory 4. Assess circumstances of first use Darrell’s Family Drink+Smoke Drugs+Drink+Smoke Smoke Bio-Psycho-Social Model Analysis of Early Drug Use Analysis: 1. Age of onset, time to regular use, use patterns, dosage form (eat, snort, smoke, inject) presence or absence of intoxication resistance. 2. Circumstances of early use: difficult or positive time in life, awareness of drug effect beyond getting high 3. What else did the drug do for you beside make you high, e.g., promote sleep, relieve depression or anxiety or boredom, help fit in, lose weight, make stronger? Assessment Questions Have you ever used alcohol or other drugs ? • Have you ever felt guilty about your use of substances? • Have ever been criticized by other for your use of substances? • Have you ever had legal difficulties related to substance use, such as a DUI or wet and reckless? • Do you have history of addiction to alcohol/other substances? • If so, when did the addiction start and what has happened since then? • Have you ever received formal treatment for addiction or attended peer support, such as 12-step meetings?
