The word ‘addiction’ these days is used to refer to a chronic condition where there is anunhealthily powerful motivation to engage in a particular behaviour. This can be driven bymany different factors – physiological, psychological, environmental and social. If we say that itis all about X, we miss V, W, Y and Z. So, some people think addicts are using drugs to escapefrom unhappy lives, feelings of anxiety and so on; many are. Some people think drugs becomeaddictive because they alter the brain chemistry to create powerful urges; that is often true.Others think that drug taking is about seeking after pleasure; often it is. Some take the view thataddiction is a choice – addicts weigh up the pros and cons of doing what they do and decidethe former outweigh the latter. Yet others believe that addicts suffer from poor impulse control;that is often true… And so it goes on.When you look at the evidence, you see that all these positions capture important aspects ofthe problem – but they are not complete explanations. Neuroscience can help us delve moredeeply into some of these explanations, while the behavioural and social sciences are better atexploring others.
