Pharmacology is a branch of science that deals with the study of drugs and their actions on living systems.
To understand how drugs work in the body we need to consider:
- type of drug
- quantity of drug used
- time taken to consume the drug
- gender, size and amount of muscle
- other psycho-active drugs used
- mood or attitude
- setting or environment.
Psycho-active drugs are substances that alter mood, thoughts, or behaviour as a result of changes in the functioning of the brain.
In this module, the term 'drug' will be used to include all psycho-active drugs including alcohol and other psycho-active substances (e.g. petrol).
Question - Give three examples of psycho-active drugs and three examples of non-psycho-active drugs? (Hint: Think about medication that affects parts of the body other than the brain.)
Since alcohol and other drug (AOD) use is a part of youth culture, it is important to understand how drugs work if you work with young people.
