The difficulty in looking for addiction symptoms is that, for a time, the behaviour of an addict is often seen as normal. Someone who is addicted to drugs may simply be seen as partying more. A person who is addicted to gambling may just be seen as blowing off some steam. But in actual fact, when scrutinised, these people are really showing signs of addiction.

Any time someone continuously chooses an action, behaviour or substance to the exclusion of everything or someone else, this person is likely an addict.

Most addicts go through a period where they deny their addiction symptoms. It is often up to those around them to spot the addiction signs early and try to persuade the addict to get help. Addictive behaviours are some of the most obvious signs of addiction and can often be seen as obsessions or compulsions.
