Symptoms of Addiction

Signs and Symptoms of Addiction to Look Out For

By

Updated March 29, 2014

All addictions, whether to substances or to behaviors, involve both physical and psychological processes. Each person’s experience of addiction is slightly different, but usually involves a cluster of some of the following symptoms of addiction. You can still be addicted even if you do not have all of the symptoms.

There are many different addictions, but similar symptoms span them all.

Some of the common symptoms of addiction are:

Signs of Addiction

Symptoms can only be experienced by the person with the addiction, whereas signs can be observed by other people. You can never know what someone else is experiencing unless they tell you, so if you are concerned that someone else may have an addiction, look for signs as well as for symptoms.

You might see some signs in an addicted person but not others. These are signs which occur across many -- but not necessarily all -- addictions:

Caution

Most of the signs of addiction have other explanations. For example, someone can be secretive because they are planning a birthday surprise for a friend. People can have changes of energy for numerous reasons, health related and otherwise. They can make new friendships and end old ones for many reasons other than addictions.

Most of the signs of addiction are similar to normal teenage behavior. Unfortunately, teenagers are one of the groups most vulnerable to addiction. Parents who are concerned about their teenage child should be very careful when discussing addiction with a teenager.

Be cautious about jumping to conclusions. Unless you have found drugs or drug paraphernalia, or have some other obvious evidence of an addiction, it is likely there is another explanation. However, do not be naïve if you have found drugs or drug paraphernalia, as you may end up with legal problems if you do not address the situation.

The most important factor in finding out whether someone has an addiction or not is trust. Trust needs to be earned, so try to be supportive. A confrontation with someone with an addiction is likely to just lead to denial and rejection from the addicted person.
