Biology - Abuse of Drugs (AQA)
One of the subjects looked at in GCSE Science is drugs. In this, the second of two quizzes on the subject, we look at the abuse of drugs - both medical and recreational. It is important to know the effects and the dangers of drugs and the damage they can do to our physical and our mental health.
Medical drugs are useful and help the body to heal or control pain. Sometimes they are modified and abused because some people enjoy the effects that they have on their bodies. Some drugs are deliberately manufactured or grown specially for recreational use. These recreational drugs can be extremely addictive and dangerous, (e.g. cocaine and heroin). When someone is dependent on (addicted to) a recreational drug, they may suffer from unpleasant withdrawal symptoms if they stop using it. That makes it very hard for them to give it up.
