What are Drugs?

Drugs are chemical substances that affect the body and brain. They change how your body works. Some drugs, like medicine from a doctor, are good because they help you when you’re sick. But there are other drugs that aren’t good for you, especially if you don’t need them for health reasons.

What is Drug Abuse?

Drug abuse is when someone uses drugs the wrong way. This means taking drugs that aren’t prescribed to you, or using drugs just to feel different or escape problems. It’s like using someone else’s prescription glasses when you don’t need them – it doesn’t help and can be harmful.

Drug abuse, also known as substance abuse, is the habitual use of drugs to alter one’s mood, emotion, or state of consciousness. In other words, drug abuse means the use of drugs without medical justification. Some people abuse drugs ignorantly while some abuse it intentionally to derive pleasure, get high, stimulate or commit a crime. Commonly abused drugs are caffeine, alcohol, cocaine, cannabis, sedative drugs, codeine, nicotine, marijuana, etc.

Drug abuse commonly brings about many behavioural problems and health complications. Some of the bad effects of drug abuse on the body are brain damage, death, accident, poverty, crime, etc.

Some ways to prevent it are:
