TOPIC: SUBSTANCE ABUSE SUBTOPICS: Types and Effects of Substances, Causes and Effects of Substance Abuse, Fighting Substance Abuse SPECIFIC OUTCOMES: 1. Describe types of substances often abused by people 2. Discuss substances and their effects 3. Explain reasons for substance abuse 4. Discuss effects of substance abuse on individuals, community, national and international levels 5. Identify institutions involved in fighting substance abuse in Zambia INTRODUCTION Substance abuse is a critical issue affecting individuals, families, communities, and the nation at large. It involves the harmful use of psychoactive substances, including alcohol and illicit drugs. Understanding the various types of substances, their effects, the reasons why people abuse them, and the consequences is essential for promoting a healthy and responsible society. This topic also explores the roles of different institutions in Zambia dedicated to combating substance abuse. CORE CONCEPTS TYPES OF SUBSTANCES OFTEN ABUSED BY PEOPLE Substance abuse is defined as the taking of something often that the body does not need and for the wrong reasons. This misuse can lead to physical, mental, and social harm. Substances can be classified in various ways, including how they are obtained and their effects on the central nervous system. Classification by Availability: 1. Over-the-counter substances: These are substances which can easily be bought without a prescription and are typically used for medical purposes when taken correctly. Examples include Panadol, Aspirin, Cafenol, Fansidar, and Vemox. Abuse occurs when these are taken in excessive amounts or for non-medical reasons. 2. Controlled substances: These are substances that can only be obtained with a doctor's prescription due to their potential for addiction or harm if misused. They can be dangerous if not used properly. Examples include Morphine, Valium, Cocaine, and Marijuana (when used illicitly). Classification by Effect on the Central Nervous System: 1. Depressants: These are substances that slow down the action of the central nervous system (brain and spinal cord). They are also known as sedatives or hypnotics. * Effects: They decrease awareness and tension, induce relaxation, and can cause drowsiness. In larger amounts, they can lead to unconsciousness, coma, or even death. * Examples: Alcohol, Mandrax, Valium. 2. Stimulants: These are substances that stimulate the central nervous system and speed up body processes. * Effects: They increase alertness, energy, heart rate, and blood pressure. They can also suppress appetite and cause sleeplessness. Prolonged use can lead to anxiety, paranoia, and heart problems. * Examples: Caffeine (found in tea, coffee, chocolate, Coca-Cola), Nicotine (in tobacco), Cocaine, Amphetamines. 3. Hallucinogens: These are substances which distort the way the brain translates impulses or messages from sensory organs, producing perceptual changes. * Effects: The brain may produce images with no basis in reality, known as hallucinations. They can also cause altered thoughts, emotions, and a distorted sense of time and self. * Examples: Lysergic Acid Diethylamide (LSD), Magic Mushrooms, Ecstasy. 4. Narcotics or Opiates: These are substances that make the senses dull and relieve pain by depressing the cerebral cortex (the outer layer of the brain responsible for consciousness, perception, memory, and learning). * Effects: They cause euphoria, pain relief, drowsiness, and a feeling of calm. They are highly addictive and can lead to severe withdrawal symptoms. Overdose can cause respiratory depression and death. * Examples: Heroin, Morphine, Codeine. 5. Inhalants or Solvents: These are diverse groups of volatile substances found in common household products. * Effects: The capillary surface of the lungs allows quick absorption of the substance into the bloodstream, leading to fast entry into the brain and intense intoxicating effects. Effects can include dizziness, slurred speech, euphoria, hallucinations, and unconsciousness. Long-term use can cause irreversible damage to the brain, liver, and kidneys. * Examples: Glue, paint, nail polish remover, powdered tobacco, Tipp-Ex, petrol, rubber cement, lighter fluid, deodorant sprays, perfume sprays.

CLASSIFICATION OF SUBSTANCES BY EFFECTS ON CNS

SUBSTANCES AND THEIR EFFECTS Different substances have distinct and often severe effects on the body and mind. 1. Alcohol: * Alcohol abuse is when one drinks too much alcohol too often. * Effects: Impaired judgment and coordination, slurred speech, memory loss, liver damage (cirrhosis), heart disease, brain damage, addiction, increased risk of accidents and violence. Long-term abuse can lead to various cancers. 2. Tobacco: * Contains harmful chemicals such as Nicotine (addictive substance), Tar (contains carcinogens), and Carbon Monoxide (reduces oxygen-carrying capacity of blood). * Effects: Lung cancer, heart disease, stroke, chronic bronchitis, emphysema, addiction, bad breath, stained teeth and fingers. It also affects passive smokers. 3. Inhalants: * These are volatile solvents and gases found in household products like glue, paint, nail polish, Tipp-Ex, petrol, and lighter fluid. * Effects: Dizziness, euphoria, slurred speech, hallucinations, loss of coordination, nausea, vomiting, brain damage, kidney damage, liver damage, heart problems, and sudden sniffing death. 4. Cannabis (Marijuana): * Also known as dagga or weed, it contains the psychoactive compound Tetrahydrocannabinol (THC). * Effects: Altered perception, impaired memory and concentration, increased heart rate, anxiety, paranoia, psychosis (in vulnerable individuals), respiratory problems (if smoked), addiction. 5. Heroin: * A highly addictive opioid drug. * Effects: Intense euphoria, pain relief, drowsiness, slowed breathing, nausea, vomiting, constipation. Overdose can lead to respiratory arrest and death. Long-term use causes severe addiction, collapsed veins, infections, and liver disease. 6. Cocaine: * A powerful and addictive stimulant drug. * Effects: Increased energy and alertness, euphoria, increased heart rate and blood pressure, paranoia, anxiety, irritability. Long-term use can lead to heart attacks, strokes, seizures, severe depression, and nasal damage (if snorted).

EFFECTS OF ALCOHOL ABUSE ON THE HUMAN BODY

REASONS FOR SUBSTANCE ABUSE There are various factors that contribute to individuals engaging in substance abuse. Understanding these reasons can help in developing effective prevention strategies. 1. Curiosity: Some people are tempted to try out substances to experience how it feels, driven by a desire for new sensations or experiences. 2. Peer Pressure: Young people often end up taking substances because they want to fit in or do what their friends are doing, fearing rejection if they refuse. 3. Ignorance: Individuals may begin experimenting with substances without being fully aware of the dangers and long-term consequences of the substances they abuse. 4. Availability of Substances: The easy accessibility of certain substances, such as alcoholic beverages, solvents (glue, Tipp-Ex, methylated spirits), and sometimes illicit drugs, makes it easier for people to acquire and abuse them. 5. Lack of Recreational Facilities: In many Zambian communities, there is a lack of adequate recreational facilities. Young people, with nowhere constructive to spend their leisure time, may resort to substance abuse out of boredom or a lack of alternatives. 6. Stress and Coping Mechanism: Some individuals turn to substances as a way to cope with stress, anxiety, depression, or trauma, seeking temporary relief from their problems. 7. Enhancement of Self-Confidence: Some believe that taking substances may help them to improve their self-confidence in various activities, such as sports, social interactions, or even examinations, creating a false sense of capability.

Signs and Symptoms of Substance Abuse: Recognising the signs and symptoms of substance abuse is crucial for early intervention. These may include: • Heavy use of perfumes or air fresheners to disguise the smell of substances. • Associating with a particular group, especially one known to abuse substances. • Possession of certain objects such as drug paraphernalia (e.g., pipes, rolling papers, syringes). • Changes in behaviour: Secretiveness, sudden mood swings, irritability, aggression, loss of interest in hobbies. • Physical changes: Dilated or constricted pupils, bloodshot eyes, changes in sleep patterns, sudden weight loss or gain, poor hygiene. • Academic/Work performance decline: Skipping school/work, poor grades, decreased productivity. • Financial problems: Unexplained need for money, stealing, selling possessions. How to Avoid Substance Abuse: Preventing substance abuse requires conscious effort and strategic decision-making. • Say no thanks: If you are offered dangerous substances, always politely but firmly decline. • Changing the subject: If someone is enticing you to use dangerous substances, you should change the subject to discourage them and shift the focus of the conversation. • Walking away: You can also physically remove yourself from the situation to avoid being tempted or pressured to take dangerous substances. • Avoiding the situation: If you know places or social gatherings where substances are abused, stay away from such environments. • Seek positive alternatives: Engage in healthy hobbies, sports, volunteering, or other constructive activities. • Build strong relationships: Surround yourself with supportive friends and family who encourage healthy choices. • Develop coping skills: Learn healthy ways to manage stress and emotions, rather than resorting to substances. EFFECTS OF SUBSTANCE ABUSE ON INDIVIDUALS, COMMUNITY, NATIONAL AND INTERNATIONAL LEVELS Substance abuse has far-reaching negative consequences that affect various aspects of life. Dependence on Substances: • Physical dependence: This occurs when one tries to withdraw from using a certain substance but experiences physical effects such as shaking, sweating, nausea, or intense cravings. The body has adapted to the presence of the drug. • Psychological dependence: This is a strong emotional craving for the drug, even without physical withdrawal symptoms. The individual feels they need the drug to function normally or to feel good. Effects on Individuals: • Health problems: Abusers are likely to experience severe health issues such as organ damage (liver, brain, heart), mental illnesses (depression, anxiety, psychosis), infectious diseases (HIV/AIDS, hepatitis from shared needles), and overdose leading to death. • Strained relationships: Relationships with friends and family may become strained or broken as a result of the abuser's behaviour, leading to isolation and lack of support. • Legal consequences: People who abuse substances risk heavy fines, imprisonment, and a criminal record, which can impact future opportunities. • Financial problems: Most substance abusers tend to spend a lot of money to sustain their habit, leading to debt, job loss, and neglect of family responsibilities. • Loss of productivity: Reduced ability to perform at school or work, leading to academic failure, job loss, and inability to contribute meaningfully to society. • Insanity: Prolonged use of certain substances can lead to severe mental health disorders, including psychosis. Effects on the Community: • Increased crime: Substance abusers often commit crimes such as murder, aggravated robbery, theft, and prostitution to acquire money to support their habit. This increases insecurity and fear within communities. • Spread of diseases: The spread of HIV/AIDS and other blood-borne diseases is likely to become rampant among abusers, especially if they are using shared needles. • Burden on healthcare and social services: Communities bear the cost of treating substance-related illnesses, rehabilitation, and providing care for terminally ill abusers. • Disruption and disharmony: Substance abuse causes disruption and disharmony within families and neighbourhoods, leading to social instability. • Intergenerational impact: Young people in homes where substance abuse occurs may perceive it as normal, influencing them to become abusers themselves. Effects on the Nation: • Economic loss: There is a significant loss of money in terms of reduced national productivity, accidents in industries, increased violence and crime, and the high costs of treatment, rehabilitation, and care for substance abusers. • Strain on law enforcement and justice systems: The government spends substantial resources on investigating, arresting, prosecuting, and incarcerating individuals involved in drug-related crimes. • Public health crisis: Substance abuse strains national healthcare systems, diverting resources from other essential health services. • Social instability: Widespread substance abuse can undermine social cohesion, public trust, and overall national development. Effects on the International Level: • Transnational crime: Drug trafficking is a major component of organised crime, often involving international networks, money laundering, and corruption that destabilises countries globally. • Global health burden: The spread of drug-resistant diseases and HIV/AIDS due to substance abuse poses challenges to global health initiatives. • Diplomatic challenges: Countries may face diplomatic tensions over drug production, trafficking routes, and international cooperation in combating the drug trade. • Economic instability: Illicit drug trade can destabilise economies, particularly in developing countries, by diverting funds from legitimate sectors and fostering corruption. INSTITUTIONS INVOLVED IN FIGHTING SUBSTANCE ABUSE IN ZAMBIA Zambia has several institutions dedicated to combating substance abuse through prevention, law enforcement, and rehabilitation. 1. Drug Enforcement Commission (DEC): * Role: Established in 1989, DEC is a government institution charged with the responsibility of curbing substance abuse and illicit drug trafficking. It investigates and prosecutes cases related to drug trafficking and substance abuse. It also conducts public awareness and sensitisation campaigns. 2. Zambia Police Service: * Role: The police fight corruption and abuse through its establishment called the Police Professional Standards Unit, which deals with police abuse and corrupt practices. Through the Victim Support Unit (VSU), the police provide services to the community by promoting and protecting the rights of victims of abuse or torture. Lawbreakers involved in substance abuse-related crimes are apprehended, arrested, and prosecuted accordingly. 3. Pharmaceutical Regulatory Authority (PRA): * Role: While not directly fighting illicit drug abuse, PRA is responsible for regulating the manufacture, importation, exportation, distribution, and sale of medicines and allied substances in Zambia. This includes controlling the availability of over-the-counter and controlled substances, ensuring they are used safely and preventing their diversion for abuse. They ensure that pharmaceutical products are of acceptable quality, safety, and efficacy. 4. Ministry of Health: * Role: Provides treatment, rehabilitation, and counselling services for individuals struggling with substance abuse through hospitals, clinics, and specialised centres. It also implements public health campaigns to raise awareness. 5. Non-Governmental Organisations (NGOs) and Community-Based Organisations (CBOs): * Role: Various local and international NGOs and CBOs work on the ground to provide prevention education, counselling, rehabilitation support, and advocacy for policies that combat substance abuse. Examples include the Catholic Commission for Justice Development and Peace (CCJDP) which carries out civic education activities to promote public awareness on issues affecting society, including human rights abuses and poverty, often linked to substance abuse.

SUMMARY Substance abuse is the harmful misuse of substances, categorised by availability (over-the-counter and controlled) and by their effects on the central nervous system (depressants, stimulants, hallucinogens, narcotics, and inhalants). Each substance, such as alcohol, tobacco, cannabis, heroin, and cocaine, carries specific and severe health risks. People abuse substances due to curiosity, peer pressure, ignorance, easy availability, lack of recreational facilities, stress, and a desire for enhanced self-confidence. The consequences of substance abuse are vast, leading to individual health problems, strained relationships, legal issues, financial ruin, increased crime rates, public health crises, and economic burdens at community, national, and international levels. In Zambia, institutions like the Drug Enforcement Commission (DEC), Zambia Police Service, Pharmaceutical Regulatory Authority (PRA), Ministry of Health, and various NGOs play crucial roles in combating substance abuse through enforcement, regulation, treatment, and prevention. ASSESSMENT QUESTIONS 1. Identify and describe two categories of substances based on how they are obtained, providing an example for each. (Outcome 1) 2. Explain the main effect of "depressants" on the central nervous system and give two examples of such substances. (Outcome 1) 3. Discuss the specific health effects of alcohol abuse on an individual's liver and brain. (Outcome 2) 4. Outline three reasons why young people in Zambia might start abusing substances. (Outcome 3) 5. Describe two signs or symptoms that could indicate an individual is abusing substances. (Outcome 3) 6. Explain two negative impacts of substance abuse on the community. (Outcome 4) 7. Identify and state the primary role of the Drug Enforcement Commission (DEC) in fighting substance abuse in Zambia. (Outcome 5) COMMON DIFFICULTIES & MISCONCEPTIONS 1. Misconception: "Only illegal drugs are harmful; prescription medications are safe." * Clarification: Many prescription medications (controlled substances) can be severely harmful and addictive if abused or taken without proper medical supervision. Over-the-counter drugs can also be dangerous if misused. 2. Misconception: "Substance abuse only affects the person taking the drug." * Clarification: Substance abuse has ripple effects that severely impact family members, friends, the community (through crime, healthcare burden), and the nation (economic loss, social instability). 3. Misconception: "I can stop anytime I want; I'm not addicted." * Clarification: Dependence (physical and psychological) can develop subtly. Many users underestimate the power of addiction and the difficulty of withdrawal without professional help. 4. Difficulty: Differentiating between the various classifications of drugs (e.g., depressants vs. stimulants). * Clarification: Emphasise the primary action on the central nervous system: depressants slow down, stimulants speed up, hallucinogens distort perception, narcotics relieve pain and dull senses, inhalants cause rapid intoxication. 5. Misconception: "Substance abuse is a moral failing, not a health issue." * Clarification: While choices are involved, substance abuse is recognised as a complex brain disease (addiction) that requires medical treatment and support, not just willpower. 6. Difficulty: Understanding the long-term, systemic effects beyond immediate health consequences. * Clarification: Highlight the interconnections between individual abuse and broader societal problems like crime, poverty, and public health crises.
