Lesson Content/Board Summary
Social Vices: Drug And Substance Abuse
Meaning of Social Vices
Social vices are undesirable behaviours or habits that are considered immoral, unhealthy, or detrimental to the well-being of individuals and society. They often go against societal norms and values, leading to negative consequences for those involved and the community at large.
Examples of social vices include:
- Drug and substance abuse
- Cultism
- Prostitution
- Gambling
- Examination malpractice
- Armed robbery
- Kidnapping
Meaning of Drug and Substance Abuse
Drug abuse refers to the excessive, compulsive, or inappropriate use of psychoactive substances, whether legal or illegal, for non-medical purposes. It involves using drugs in a way that harms the user or others, often leading to physical, psychological, social, or legal problems.
Substance abuse is a broader term that includes the misuse of any chemical substance, including alcohol, tobacco, prescription medications, and illicit drugs, leading to harmful effects.
Types of Drugs and Substance Abuse
Drugs and substances commonly abused can be classified into different categories based on their effects on the central nervous system:
- Depressants: These drugs slow down brain activity, leading to relaxation, drowsiness, and reduced inhibition.
- Examples: Alcohol, sedatives (e.g., Valium, Xanax), opioids (e.g., heroin, codeine, tramadol).
- Stimulants: These drugs speed up brain activity, increasing alertness, energy, and heart rate.
- Examples: Cocaine, amphetamines (e.g., methamphetamine), nicotine, caffeine.
- Hallucinogens: These drugs alter perception, thoughts, and feelings, causing hallucinations and distorted reality.
- Examples: LSD, psilocybin (magic mushrooms), ecstasy (MDMA), cannabis (marijuana) in high doses.
- Cannabis: Often considered in its own category due to its mixed effects (depressant, stimulant, and hallucinogenic properties).
- Examples: Marijuana, hashish.
- Inhalants: Volatile substances that produce mind-altering effects when inhaled.
- Examples: Solvents (e.g., glue, paint thinners), aerosols, nitrites.
Ways of Abusing Drugs and Substances
Drugs and substances can be abused through various methods, each carrying its own risks:
- Oral Ingestion: Swallowing pills, liquids, or edibles. This is common for prescription drugs, alcohol, and some illicit substances.
- Inhalation/Smoking: Breathing in the smoke or vapour of a substance. This includes smoking marijuana, crack cocaine, or inhaling solvents.
- Injection: Using a needle to inject drugs directly into a vein (intravenous), muscle (intramuscular), or under the skin (subcutaneous). This method is common for heroin and other opioids.
- Snorting/Insufflation: Inhaling powdered drugs through the nose, where they are absorbed through the nasal membranes. Examples include cocaine and some prescription pills.
- Suppository: Inserting drugs into the rectum or vagina for absorption.
- Transdermal: Applying drugs to the skin in patches or creams for slow absorption into the bloodstream.
