Types of Drugs Study Note

Drugs are substances that change how your body works when you take them. They can be classified into two main groups based on how they affect you. Therapeutic drugs help treat illnesses and improve health, like paracetamol which reduces fever and pain when you're sick. Recreational drugs, on the other hand, are taken for pleasure and can be harmful, including alcohol and tobacco commonly used in Nigeria. Another way to classify drugs is by how they affect your brain and nervous system. Stimulants like caffeine speed up your body functions, while depressants like alcohol slow them down. Hallucinogens change how you see and hear things. Understanding these categories helps you recognize which drugs are safe for medical use and which ones are dangerous. Always remember that even medicine can be harmful if misused.

💡 Exam tip: When answering questions on drug types, clearly state whether the drug is therapeutic or recreational, and explain how it affects the body's systems.
Objective 2 of 2
Drug Abuse Study Note

Drug abuse means using drugs in ways that damage your health or harm society. This includes taking prescribed medicines wrongly, using illegal substances, or misusing substances like alcohol and tobacco. When someone abuses drugs, they often become dependent, meaning their body and mind crave the substance constantly.

Nigeria faces serious drug abuse problems, particularly with substances like cocaine, heroin, and cannabis. Many young Nigerians have fallen into drug addiction through peer pressure or trying to escape life problems. Drug abuse leads to serious consequences: damaged organs, mental health issues, broken families, crime, and even death.

Understanding drug abuse matters because it helps you make better choices and recognize warning signs in friends. Prevention is always better than dealing with addiction later.

💡 Exam tip: When answering questions about drug abuse, always mention both the health effects and social consequences to get full marks, as examiners expect comprehensive understanding.
