Substance Use Disorders
Definition: Chronic difficulties in resisting the desire to drink alcohol or take drugs.
Substance: Any natural or synthesized product that has psychoactive effects.
Substance Intoxication: Symptoms arise as a result of the physiological effects of a substance on the central nervous system, which depend on the substance and the setting.
Substance Withdrawal: Symptoms that occur when individuals who have been using substances heavily for prolonged periods stop or significantly reduce use.
Criteria for Substance Use Disorder
Substance Abuse:
Involves recurrent use of a substance leading to:
Failing to fulfill important obligations
Using the substance in physically hazardous situations
Legal problems as a result of substance use
Continuing to use the substance despite social or legal issues.
Substance Dependence:
Characterized by:
Tolerance: Diminished effects from the same dose of a substance, necessitating increased amounts for the same effect.
Categories of substances:
Central Nervous System (CNS) Depressants
CNS Stimulants
Opioids
Hallucinogens and Phencyclidine (PCP)
Cannabis
Depressants
Effects: Slow down the central nervous system.
Moderate doses lead to:
Relaxation and drowsiness
Reduced concentration
Impaired judgment and motor skills.
Heavy doses can cause:
Stupor or even death.
Alcohol Use
Effects on the Brain:
Low Doses: Feelings of self-confidence, relaxation, euphoria, and decreased inhibition.
Increasing Doses: Symptoms of depression, fatigue, decreased motivation, sleep disturbances, depressed mood, and confusion.
Effects are influenced by whether consumed on an empty or full stomach and can interact fatally with various substances.
Long-Term Effects: Include a range of health and psychological issues.
Benzodiazepines and Barbiturates
Usage: Legally manufactured and sold by prescription as sedatives for treating anxiety and insomnia.
Risks: Decrease in blood pressure, respiratory rate, and heart rate; overdose can lead to death from respiratory arrest or cardiovascular collapse.
Stimulants
Function: Activate the central nervous system.
Cause feelings of energy, happiness, reduced need for sleep, and decreased appetite.
Cocaine:
A highly addictive substance derived from the coca plant.
Crack Cocaine: Freebase cocaine processed into small chunks for smoking.
Effects: Produces intense euphoria but quickly wears off, leading to complications like anxiety and paranoia.
Cocaine Intoxication
Symptoms: Euphoria, grandiosity, impulsivity, compulsive behavior, agitation, and medical complications.
Impact on Brain: Activates reward areas which amplify the sense of pleasure.
Amphetamines
Usage: Prescribed for attention problems, narcolepsy, and chronic fatigue.
Mechanism: Release dopamine and norepinephrine; rapid tolerance and dependence can develop.
Nicotine
Definition: An alkaloid found in tobacco, primarily consumed via cigarettes.
Effects: Mimics fight-or-flight responses; associated with severe health issues like lung cancer and heart disease.
Withdrawal Symptoms: Include depression, insomnia, irritability, anxiety, and increased appetite.
Caffeine
Profile: Most commonly used stimulant.
Mechanism: Stimulates CNS leading to increased levels of dopamine, norepinephrine, and serotonin, resulting in heightened metabolism and blood pressure.
Opioids
Source: Derived from opium poppy sap used for pain relief.
Examples: Morphine, heroin, codeine, methadone.
Effects: Lead to drowsiness, lethargy, and suppressed respiratory and cardiovascular systems, which can be fatal.
Hallucinogens, PCP, and Cannabis
Hallucinogens: Produce perceptual changes at low doses; include substances like LSD and peyote.
PCP (Phencyclidine): Can have severe effects including chronic cough and respiratory issues.
Cannabis: Forms various psychoactive compounds with complex effects on cognition and physical health.
Inhalants
Nature: Volatile substances inhaled for psychoactive effects.
Risks: Chronic use can cause permanent central nervous system damage and be life-threatening.
Theories of Substance Use Disorders
Biological Factors
Alterations in reward centers leading to cravings, genetic factors affecting neurotransmitter function, and sensitivity of dopamine receptors.
Psychological Factors
Influence of parental modeling, coping with stress through substance use, and behavioral undercontrol leading to prior substance use issues.
Sociocultural Factors
Environmental influences, including poverty and family dynamics, reinforcing substance use behaviors.
Gender Differences
Societal expectations and risk factor prevalence vary between genders, with women generally facing fewer risk factors and suffering from alcohol-related health issues at lower consumption levels.
Treatments for Substance Use Disorders
Biological Treatments
Include antianxiety medications, antidepressants, and drug antagonists that block or alter substance effects. Methadone maintenance programs for heroin addiction exemplify one approach.
Psychosocial Treatments
Focus on relapse prevention strategies, cognitive-behavioral techniques to change thought patterns regarding substance use, and support organizations like Alcoholics Anonymous (AA).
Substance Use Treatment for Older Adults
Employ nonconfrontational approaches with a focus on emotional states related to substance use, rebuilding social networks, and respecting the needs of older patients through closely coordinated community resources.
Prevention Programs
Address college drinking and related problems effectively through educational approaches that encourage moderation rather than insistence on total abstinence. They adopt a harm reduction model, emphasizing safety and realistic drinking behaviors.
Gambling Disorder
Definition: Persistent and recurrent problematic gambling behaviors causing significant distress or impairment.
Associated with issues in substance use, mental health, and family history of substance abuse.
More prevalent in men and linked to the same brain regions impacted by substance dependencies.
Treatment for Gambling Disorder
Cognitive-Behavioral Therapy: Focus on altering distorted beliefs surrounding control and gambling, replacing harmful behaviors with positive coping strategies, and addressing underlying emotional struggles.
