      • Risk of psychological dependence.

    • Medical Uses:

      • Some are used medically as anesthetics (e.g., nitrous oxide).
      • Limited approved usage due to safety concerns.

    • Legal Status And Regulations:

      • Many inhalants are legal household products; misuse is illegal.
      • Regulations focus on preventing abuse rather than outright bans.

    • Withdrawal Symptoms:

      • Irritability, insomnia, cravings.
      • In severe cases, withdrawal can lead to neurological symptoms.

    • Medical applications include treating ADHD with medications like methylphenidate and amphetamines.
    • Stimulants have anorectic properties, suppressing appetite.
    • Withdrawal symptoms manifest as fatigue, depression, and increased appetite.
    • Intense cravings for the substance characterize withdrawal.
    • Classified as Schedule II controlled substances in many jurisdictions, necessitating stringent prescription and distribution regulations.

    Depressants

    • Depressants reduce brain activity, inducing sedation and relaxation.
    • Inhibition of neurotransmitters, particularly GABA, contributes to reduced anxiety.
    • Moderate to high potential for abuse, as seen with benzodiazepines and alcohol.
    • Dependence can manifest physically and psychologically.
    • Medical uses include treating anxiety, insomnia, and seizures.
    • Anesthesia during surgical procedures relies on depressants.
    • Withdrawal symptoms encompass anxiety, insomnia, seizures, and tremors.
    • In severe cases, delirium, especially during alcohol withdrawal, can occur.
    • Generally legal, though most require prescriptions.
    • In the United States, benzodiazepines are classified as Schedule IV controlled substances.

    Inhalants

    • Inhalants produce short-term euphoria due to rapid delivery of chemicals to the brain.
    • Effects include dizziness, impaired judgment, and altered sensory perception.
    • Dependence potential ranges from low to moderate, often leading to habitual use.
    • The intense yet ephemeral high can encourage repeated use.
    • Limited medical uses exist, such as anesthetics or specific medical procedures.
    • Some formulations, like nitrous oxide, find medical applications.
    • Withdrawal symptoms include headaches, nausea, and irritability.
    • Cravings and withdrawal effects are less prevalent compared to stimulants and depressants.
    • Generally legal for household use; however, specific substances have restrictions.
    • Substance abuse laws primarily focus on inhalant misuse rather than legal use.

    Antidepressants

    • Function: Treat depression, anxiety, and some personality disorders
    • Classes:
      • SSRIs (Selective Serotonin Reuptake Inhibitors): Increase serotonin levels in the brain (e.g., fluoxetine, sertraline)
      • SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors): Increase serotonin and norepinephrine levels (e.g., venlafaxine, duloxetine)
      • Tricyclic Antidepressants (TCAs): Block the reuptake of serotonin and norepinephrine (e.g., amitriptyline, nortriptyline)
      • MAOIs (Monoamine Oxidase Inhibitors): Inhibit the breakdown of neurotransmitters, increasing their levels (e.g., phenelzine, tranylcypromine)

    Antipsychotics

    • Function: Manage psychosis, including schizophrenia, bipolar disorder, and severe depression with psychotic features
    • Types:
      • Typical Antipsychotics: Block dopamine receptors (e.g., haloperidol, chlorpromazine)
      • Atypical Antipsychotics: Act on a broader range of receptors, including serotonin and dopamine (e.g., risperidone, olanzapine)

    Side Effects

    • Antidepressants:
      • Common: Nausea, weight gain, insomnia, sexual dysfunction
      • Rare: Increased suicidal thoughts in adolescents
    • Antipsychotics:
      • Typical: Extrapyramidal symptoms (tremors, rigidity), tardive dyskinesia, sedation
      • Atypical: Metabolic syndrome (weight gain, diabetes risk), agranulocytosis (low white blood cell count)

    Psychopharmacology

    • Definition: The study of how medications affect mood, behavior, and mental state.
    • Goals:
      • Symptom relief: Achieve remission of mental disorder symptoms
      • Improve quality of life: Enhance overall functioning and well-being
      • Maintenance therapy: Long-term treatment to prevent relapse in chronic conditions
    • Considerations:
      • Genetic factors: Response to medications can vary based on genetics
      • Integrated treatment: Combining medications with psychotherapy often leads to better outcomes
