WAEC SSCE Biology
Study notes for Health and hygiene — part of the WAEC SSCE Biology syllabus. 3 learning objectives with explanations and exam tips.
Drug abuse means using drugs in ways that harm your health and wellbeing. This includes taking prescription medicines wrongly, using illegal drugs like cannabis, or misusing substances like cough syrups and petrol sniffing. When people abuse drugs, they take more than recommended doses or use them for purposes other than medical treatment.
In Nigeria, many young people abuse cough syrups containing codeine to get high, which damages their brains and organs over time. Drug abuse leads to serious problems like addiction, where your body becomes dependent and you cannot stop using the substance. Other effects include poor school performance, mental health issues, damaged relationships, and sometimes death.
The causes of drug abuse include peer pressure, stress, curiosity, poverty, and lack of proper guidance from parents and teachers. Prevention requires good counseling, education about drug dangers, and strong family support.
Community health cleanliness refers to the practices and conditions that keep our surroundings clean and disease-free. This includes proper disposal of waste, maintaining clean water sources, and ensuring public spaces are sanitary. When a community practices good hygiene, diseases spread less easily among people living together.
Think about Lagos State's sanitation efforts where the government organizes monthly environmental sanitation days. Residents clean streets, drains, and public areas together. This prevents cholera and typhoid outbreaks that thrive in dirty environments. Good community hygiene also involves proper sewage systems, regular street sweeping, and keeping markets clean where many people gather daily.
When communities neglect cleanliness, diseases like malaria, dysentery, and skin infections increase rapidly. Schools and hospitals must maintain high hygiene standards to protect vulnerable people.
Drug abuse refers to the misuse of substances that alter your mind or body in harmful ways. This includes using prescription medicines in ways not intended by doctors, taking illegal drugs, or overusing legal substances like alcohol and tobacco. When someone abuses drugs, they use them excessively or for wrong purposes, which damages their physical and mental health.
Consider a common Nigerian example: when students take codeine-based cough syrups not to treat cough but to get high, that's drug abuse. Similarly, using sleeping pills without a doctor's prescription or drinking alcohol to escape problems are forms of drug abuse.
The consequences are serious—addiction, organ damage, poor school performance, and even death. Understanding this distinction between proper medicine use and abuse is crucial for your health and wellbeing.
