People can develop an addiction or dependency to almost anything. Initially, they may find enjoyment from engaging in a particular activity (for example, gambling, gaming or sex) or from using substances (such as alcohol, drugs or caffeine).
An addiction can develop as a result of a variety of circumstances; in reaction to stress, as a way of coping with other difficulties or because of environmental factors, such as pressure from others. This can then develop into a physical and/or psychological dependency, which continues to further affect areas of day-to-day functioning and both mental and physical health.
