Substance Use and Age
Overview
Substance use occurs throughout the life cycle, from fetuses to older adults.
Pregnancy and Infancy
Risks associated with pregnant women: There are no safe drugs for pregnant women.
Excessive alcohol use:
- Can result in fetal alcohol syndrome (FAS).
- Children with FAS are characterized by smaller size, smaller heads, and failure to develop normally.Cocaine use:
- Infants exposed to cocaine in utero may exhibit sleeping and eating problems, unusual levels of irritation, and high-pitched cries.
Childhood and Adolescence
Children also abuse substances, typically legal and accessible.
Alcohol: Most frequently abused drug among adolescents.
Patterns of adolescent substance abuse include experimentation and usage in social settings for relaxation or intoxication.
Teens with addiction are prone to illegal activities.
Adulthood
Substance abuse is prevalent in adults.
Approximately 10% of the adult population regularly abuses alcohol.
Patterns of substance abuse can vary across minority groups:
- Cocaine: More common among African Americans.
- Alcohol: Preferred by White and Hispanic individuals.
Scope of the Problem Today
Substance abuse incurs significant financial and human costs.
Many deaths from falls, drowning, and burns are connected to alcohol and drug use.
Individuals with serious mental illness who also abuse chemicals are said to have a dual diagnosis.
Chemicals of Abuse
Alcohol
Effect: Alcohol exerts a depressant effect on the CNS.
Intoxication symptoms:
- Slurred speech
- Unsteady gait
- Lack of coordination
- Impaired attention/memory/judgmentOverdose risks:
- Vomiting, unconsciousness, and respiratory depression.
- Complications may lead to aspiration pneumonia or pulmonary obstruction. - Alcohol-induced hypotension can result in cardiovascular shock and death.Treatment of overdose:
- Options include gastric lavage or dialysis and supporting respiratory and cardiovascular function.
Narcotics
Classification: CNS depressants present naturally, semi-synthetically, and synthetically.
Examples:
- Naturally occurring: Opium, morphine
- Semi-synthetic: Heroin, hydromorphone, thebaine derivatives.
Stimulants
Commonly abused stimulants:
- Caffeine
- Cocaine, crack
- Prescription medications (e.g., amphetamines, appetite suppressants, methylphenidate (Ritalin), cannabis).
Hallucinogens
Comprised of natural and synthetic substances that alter reality perception.
Examples:
- Peyote cactus, mescaline
- Lysergic acid diethylamide (LSD)
- Psilocybin
- Phencyclidine (PCP)Users may experience varying effects from profound insights to “bad trips.”
Designer Drugs
Cocaine and Crack: Commonly abused varieties.
Designer drugs: Created by manipulating the molecular structure of existing drugs.
Examples: MDMA (Ecstasy), STP, “Ice.”
Other Medications
Many therapeutic drugs can be abused.
Examples:
- Morphine, hydromorphone
- Amphetamines
- Methylphenidate (Ritalin)
- Diazepam (Valium), laxatives, diuretics.
Inhalants
Definition: Volatile substances or chemical gases inhaled for their effects.
Examples: Alcohol solvents, gasoline, glue, paint thinner, and nicotine.
Complications: Can lead to significant health risks including sudden death, respiratory depression, hyperactive motor responses, loss of coordination, and seizures.
Characteristics of Substance Use and Abuse
Causes of Substance Abuse
Unknown origins: Causes are not definitively known.
Biological theories: Suggest variations among ethnic groups provide genetic and biochemical explanations for substance abuse.
Psychological theories: Personality and emotional problems may lead to substance abuse.
Environmental theories: Include the individual, family, and sociocultural surroundings affecting substance abuse.
Stages of Addiction
Early stage: The individual can still use without adverse effects.
Middle stage: Increased intoxication episodes occur as the body adapts; tolerance develops, needing more for the same effect.
Chronic (late) stage: High tolerance, leading to loss of control over behavior associated with substance use.
Criteria for Diagnosis
Individuals must meet specific criteria:
- The substance use pattern must be disabling, leading to impaired functioning and distress.
- Signs of tolerance, withdrawal, and dependence must be exhibited.

Treatment Models
Disease model: Considers substance abuse a disease requiring treatment.
12-step process: Focuses on admitting powerlessness and seeking help from a higher power.
Medical model: Views addiction as a public health issue, considering both chronic and acute diseases.
Psychiatric models: See substance abuse as an expression of underlying emotional or mental disorders.
Sociocultural models: Emphasize changing environmental factors to treat substance abuse.
Relapse
Definition: The recurrence of substance-abusing behaviors after a period of abstinence.
Individuals who relapse often experience distressing emotions.
Nursing/Therapeutic Process
Nursing diagnoses for clients with substance abuse problems are based on identified issues and goals.
Care plans must be tailored individually for each client, recognizing the challenges and frustrations of treating substance-related problems.
