Addiction cannot be understood from an isolated perspective. It is a complex human condition, a condition rooted in the individual experience of the sufferer and also in the multi-generational history of his or her family and—not least—also in the cultural and historical context in which that family has existed.

- Gabor Maté, Fundamentals of Addiction, 2014, p.xvi

Addiction involves psychological dependence and means that the drug is at the centre of the person’s thoughts, feelings and activities. The person may have to use more and more of the drug just to feel normal. They may want to stop, but can’t.

Another way of describing addiction is the presence of the four C’s:

    1. Craving
    2. Loss of Control of amount or frequency of use
    3. Compulsion to use
    4. Use despite Consequences
