Different people process addictive substances differently, so there is no quantitative test for determining whether you have a pathological addition. In general, addiction assessment is more qualitative, having to do with how you interact with a potentially addictive substance rather than how much of it is consumed. Some people have a much lower threshold for addiction, and develop addictive behavior despite consuming relatively little of the substance in question. Others can consume quite a bit of the substance, which may cause problems with health and relationships, but never exhibit traditionally addictive behavior.
Here are some questions to ask yourself if you suspect you may be struggling with addiction.
Does the Substance Define Your Sense of Self?
If the substance in question is such a large part of your life that you can imagine living without it, then there is a good chance that your thinking towards the substance has been altered in a negative way. Is consumption of the substance being balanced with consumption of other things that you enjoy?
Has Your Consumption Increased?
Have you noticed a sudden spike or a steady increase in consumption with no signs of dropping off again? Addicts often find they need to constantly increase their consumption of the substance in question in order to derive pleasure from it at all.
Can You Stop Easily?
If you can stop doing the behavior in question for an extended period of time, it is often a good sign. However, bear in mind that quitting means breaking a pattern of consumption, not just stopping for a few days before resuming the behavior. If you regularly tell yourself that you are going to quit, only to begin doing the same thing after a brief time away, you may have an unhealthy relationship with the substance in question.
Regardless of your answers to these questions, if you suspect you may have an addiction, talk to your doctor or a counselor. They can help you sort through your feelings toward the substance in question and get addiction treatment if needed.
