    Study Notes

    Chapter 2: Pharmacology of Psychoactive Substances

    • Psychoactive Substances (PAS) are substances that affect the central nervous system (CNS) and modify behavior or perception. The CNS includes the brain and spinal cord.
    • Substance use can lead to physical and mental health problems, poor healthcare access, and higher risk of accidents.
    • Substance use increases risk of sexually transmitted diseases (STDs) and Hepatitis.
    • Risks include poor work performance, family conflicts, violence, crime and suicide.
    • Substance users may neglect or fail to follow medical advice.

    Substance Use Disorders (SUD)

    • Two systems categorize SUD: the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM).
    • Both WHO and APA (the American Psychiatric Association) revise diagnostic criteria periodically.
    • DSM-5 lists 11 criteria for substance use disorders (SUDs), with 2-3 criteria indicative of mild SUD, 4-5 moderate, and six or more severe.
    • Tolerance, withdrawal, and substance-induced mental disorders are also described in DSM-5.

    Pharmacology

    • Pharmacology examines the effects of psychoactive substances on the body and brain.
    • The effects vary based on the substance type, dose, method of use, and duration of use.
    • Factors include age, gender and frequency.

    Absorption and Distribution

    • Different routes (smoking, inhaling, injecting, oral etc.) affect how quickly active ingredients in a substance reach the brain, and how quickly the effects appear.

    Metabolism and Elimination

    • The liver is primarily responsible for breaking down substances into metabolites, which are then excreted.

    Brain and Substance Use

    • The central nervous system (CNS) is composed of the brain and spinal cord.
    • The peripheral nervous system (PNS) includes all other nerves.
    • The CNS has parts such as the Brain Stem, Limbic System, Cerebral Cortex, etc.
    • Neurons communicate through neurotransmitters.
    • Psychoactive substances can affect neuron function.

    Conventions

    • UN International Drug Control Conventions aim to safely use potentially hazardous drugs.
    • One such single convention exists for Narcotic Drugs from 1961 and these aim to regulate and control drugs.

    Addiction as a Disease

    • Addiction is conceptualized from different points of view.
    • Addiction has signs, symptoms and changes in brain function and structure.
    • Brain imaging studies show changes in the brain following habitual substance use.
    • Addiction can cause chronic damage to the brain structure and function.

    Schedule of Controlled Substances

    • Countries classify drugs based on addiction potential.
    • Schedules (I-V) list drug types from most to least potential for abuse.
    • Schedules vary between countries.

    Classification of Psychoactive Substances

    • Categorization of substances based on their effects; for example, pain relief, mood changes, perceptual distortions etc.

    Opioids

    • Examples include opium, morphine, codeine, heroin, etc.
    • They are commonly used to relieve pain.
    • They can induce euphoria and have various long-term effects.

    Depressants

    • Examples include alcohol, barbiturates, benzodiazepines, etc.
    • They slow down the central nervous system's functions.
    • Over-use and abuse can cause serious health consequences.

    Stimulants

    • Examples include nicotine, caffeine, amphetamines, and cocaine etc.
    • They increase the activity of the central nervous system.
    • Abuse can lead to serious health problems.

    Hallucinogens

    • Examples include LSD, mescaline, psilocybin etc.
    • They distort perception and emotions.
    • Frequent use can lead to psychotic symptoms and other serious effects.

    Other Categories

    • Include Cannabis, Inhalants, Khat (Miraa), Anabolic Steroids.
    • They have unique properties and risks, requiring separate discussion.
    • Anabolic Steroids – increase muscle growth and strength.

    Pharmacotherapy

    • Pharmacotherapy uses medications to manage mental health conditions.
    • It includes methods for handling substance withdrawal and overdose situations, and managing cravings or long-term effects.
