What are drugs and how can they affect us?

Drugs are chemicals that affect how the body works. Some drugs can be helpful to the body, while others can cause harm. There are two types of drugs: medical and recreational. Paracetamol and antibiotics are examples of medical drugs. In the UK today, some recreational drugs are legal, such as alcohol, cigarettes, and caffeine. Others, such as ecstasy and cannabis, are illegal.

Drugs can be used in medicine to affect the body positively. For example, some drugs can act as painkillers—this means they stop pain or make it less bad. Some drugs can even help with anxiety and depression. Drugs such as antibiotics can be used to help fight infection, which is crucial in medicine. When drugs are used too often and recreationally, they can cause harm to the body. Most drugs can be addictive if overused and addiction can cause profound harm to an individual’s wellbeing, happiness, and quality of life.
