3.1.1 Before reading this article:

Take some time to think about what ‘addiction’ means to you – how chemical and non-chemical substances can be abused and how they can lead to dependent behaviour that can affect individuals and the society in which they live. Write down your ideas.

This short exercise may be useful to establish your personal viewpoint on the subject of ‘addiction’. Your perspective may result from knowing someone who is addicted and having personal experience of the factors that are involved, or perhaps, your insights are more academic and derived from studying scientific literature or other media.

Before reading the extract, you may wish to study the neuroanatomy of the mesolimbic-frontocortical system. The location of this system in the rat brain can be found in the textbook supporting SD805 – Carlson (2007) pp. 113–128.
