Summary of Drug Addiction: Causes, Prevention, and Treatment

## Introduction Drugs are substances (other than ordinary food) whose frequent use alters the body or mind and can lead to addiction. This material summarizes the basic classification of drugs, their effects, risks, and treatment and support options. This text is intended for high school students and explains concepts with practical examples. > Definition: A drug is any substance, other than food, whose frequent use alters bodily or mental functions and can cause addiction. ## Drug Classification Drugs can be classified by legal status, origin, and their effect on the central nervous system. ### By Legal Status - **Legal Drugs**: alcohol, tobacco, some medications. - **Illegal Drugs**: heroin, hashish, cocaine, LSD, marijuana (in some countries), methamphetamine. ### By Origin - **Natural**: marijuana, hashish, some hallucinogenic mushrooms, cacti, extracts from certain frogs. - **Chemical (Synthetic)**: LSD, ecstasy, heroin (often modified), cocaine (processed), some medications. ### By Effect on the Central Nervous System The table below compares the main categories: | Category | Examples | Main Effect | Risks / Notes | |---|---:|---|---| | Depressants ("Downers") | Alcohol, sedatives, some sleeping pills | Suppress CNS, calm, slow reactions | Risk of overdose, impaired breathing | | Narcotics / Opioids | Heroin, morphine, opium | Pain relief, euphoria | Strong addiction, risk of overdose, substitution possible | | Stimulants | Caffeine, cocaine, methamphetamine | Accelerate CNS, increased energy and alertness | Nervousness, cardiovascular risks | | Hallucinogens | LSD, "magic" mushrooms, peyote | Altered perception, hallucinations | Psychoses, risk of a bad trip | | Inhalants | Glues, thinners, aerosol sprays | Rapid onset of effect when inhaled | Can lead to sudden death even with first use | | Cannabinoids | Marijuana, hashish | Combination of sedative, stimulant, and hallucinogenic effects | Long-term use alters memory and motivation | | Anabolic Steroids | Prescription medications, abused by athletes | Increase muscle mass, not typically psychoactive | Health complications, penalties in sports | > Definition: Cannabinoids are substances found in marijuana and hashish that affect the brain and can have effects similar to sedatives, stimulants, and hallucinogens. ## Effects and Consequences of Use We distinguish between biological, psychological, and social consequences. ### Biological Effects - General decline in health - Poor eating habits (e.g., loss of menstrual cycle in women), neglect of hygiene - Damage to the liver, kidneys, digestive tract, and nervous system - Increased risk of infectious diseases (hepatitis, HIV) ### Psychological Effects - Emotional disturbances: irritability, lability - Problems with concentration and memory - Extreme apathy or hyperactivity - Changes in values and social interests - Severe psychotic symptoms: hallucinations, delusions, behavioral disruption ### Social Impacts - Loss of interest in school or work, absenteeism - Change in social circle; isolation from family - Financial problems and potential involvement in criminal activity - Most serious consequence: death (overdose, accidents, health complications) Did you know that long-term use of some drugs can permanently affect brain structure and function, and impair decision-making ability in adulthood? ## Prevention and Intervention (Overview of Options) Note: Detailed information on prevention and warning signs is provided elsewhere and is not discussed here. 1. Secondary Prevention (Early Intervention) - Early identification of experimentation in adolescents - Parents should look for changes: secretiveness, change in appearance, weight loss, drug-related paraphernalia - Seek professional help early 2. Tertiary Prevention (Treatment and Resocialization) - Detoxification in a medical facility: medical care for withdrawal symptoms - Resocialization: communities, supported housing, contact centers (K-cent
