Chapter 10: 

1. Substance Abuse: Depressants

Depressants slow the central nervous system's activity, leading to relaxation and reduced inhibitions. This class of drugs can significantly affect judgment and coordination, and long-term use can lead to dependence. The three primary groups of depressants include:

  • Alcohol: Widely consumed worldwide with over 2 billion users; over half of U.S. adults drink occasionally. Sales in the U.S. exceed billions annually.

  • Sedative-hypnotic drugs: Initially barbiturates, now largely replaced by benzodiazepines due to their safety profile.

  • Opioids: Medications utilized for pain relief but carry a high risk of addiction.

2. Alcohol
Statistics and Drinking Patterns
  • Binge Drinking: Defined as consuming 5 or more drinks during a single occasion. Approximately 25% of U.S. adults binge drink at least monthly, while 6.5% are classified as heavy drinkers (5 or more times a month).

    • Demographics: heavy drinking is significantly more common in males versus females at a ratio of 2:1.

  • Effects of Ethyl Alcohol: Ethanol is quickly absorbed into the bloodstream, leading to its immediate effects on the central nervous system, particularly regarding the neurotransmitter GABA, which inhibits neural activity and induces relaxation.

    • Concentration Effects:

    • 0.06%: Relaxed and comfortable

    • 0.09%: Intoxication begins

    • 0.55%: Risk of death

  • Metabolism: Alcohol can only be deactivated through metabolic processes, an average rate of approximately 25% of an ounce per hour.

3. Alcohol Use Disorder (AUD)
Prevalence and Demographics
  • Alcohol Use Disorder affects various demographics differently:

    • White Americans: 5.7%

    • Hispanic Americans: 5.3%

    • Black Americans: 4.5%

    • American Indians: 7.1% (highest prevalence)

    • Asians: 3.8% (many have a genetic aversion to alcohol due to a deficiency in alcohol dehydrogenase).

Treatment Strategies
  • Treatment Options:

    • Aversion Therapy: Creates negative associations with alcohol consumption.

    • Cognitive Behavioral Therapy (CBT): Emphasizes planning and self-regulation to prevent relapses and patterns of drinking.

4. Biological and Cognitive Impacts of Alcoholism
Cognitive and Psychological Effects
  • Alcoholism can lead to impairments in various cognitive functions, namely:

    • Memory and attention deficits

    • Speed of cognitive processing and reaction time.

Withdrawal Symptoms
  • Withdrawal from alcohol may yield severe psychological and physical symptoms:

    • Physical: Tremors, sweating, nausea, rapid heart rate.

    • Psychological: Increased anxiety and depressive symptoms may occur, leading to serious complications.

    • Delirium Tremens (DTs): A severe form of withdrawal that includes confusion, hallucinations, and seizures.

Social Impacts
  • Alcoholism is implicated in 1/3rd of all suicides, homicides, assaults, and fatal accidents in the U.S.

  • It highly affects children of individuals with alcoholism, often leading to long-term issues of low self-esteem and marital problems.

5. Sedative-Hypnotic Drugs
  • Mechanism of Action: These drugs, also known as anxiolytics, produce calming effects, with low doses yielding relaxation and higher doses leading to sleep induction.

    • Historical Context: While barbiturates were once the go-to sedative, they have largely been replaced by benzodiazepines (e.g., Xanax, Ativan) due to a better safety profile.

  • Effects of Long-term Use: Chronic consumption can lead to dependence, impaired cognitive function, anxiety, and withdrawal symptoms upon cessation.

6. Opioids
  • Opium Derivatives: Key drugs include heroin, morphine, and codeine, widely used for pain relief but consequently leading to high addiction potential.

  • Psychological Effects: Opioids attach to brain receptors for endorphins, producing significant pleasure and relaxation, which can lead users to prioritize drug use over basic needs.

  • Withdrawal Symptoms: Withdrawal can result in severe anxiety, muscle aches, nausea, and blood pressure spikes, severely impacting quality of life.

  • Epidemic Statistics: Opioid misuse has increased significantly, with recent data showing a rise in overdose deaths since COVID-19.

7. Stimulants
  • Main Types: Cocaine, amphetamines, and nicotine are primary stimulants, with widely varying effects and addiction potential.

  • Consequences of Misuse: Regular use may lead to stimulant use disorder, which dominates an individual's lifestyle and health.

8. Overview of Substance Use Disorders
  • Definition: Includes alcohol, cocaine, and gambling as significant focus areas in mental health and addiction discourse.

    • Identifying Characteristics: Involve problematic substance use leading to consequences across physical and mental health spectrums.

  • Consequences of Abuse: Relationships, employment, and day-to-day functioning become increasingly difficult due to substance-related behaviors.

9. Treatment Approaches for Substance Use Disorders
  • CBT and Integrated Treatment: Incorporates both psychological and pharmacological strategies to treat substance use disorders effectively.

  • Importance of Community Support: Coordination among healthcare providers and community resources can significantly improve treatment outcomes.
