The forming of an addiction does not imply a unique mechanism of getting used to particular occupations or substances. On the contrary, experts often distinguish psychological and physical aspects of addiction. They can be interconnected (as in the case of alcohol or drug addiction), or be manifested without interconnection (Internet addiction). In other words, when talking about addiction, we should mind that it can either refer to a substance dependence, or behavioral malfunctions.
What is a psychological, or behavioral addiction then? According to the website of the American Society of Addiction Medicine, it is a chronic disease of brain reward, motivation, memory, and related circuitry, which is reflected in an individual pathologically pursuing reward and/or relief by performing certain actions (ASAM). The Collins English Dictionary defines addiction as a condition of being abnormally dependent on a certain habit. Psychological addiction is followed by such symptoms as an individual becoming obsessed with an object or activity; engaging in the activity or habitual behavior even if it is potentially harming; denying problems connected to the addiction and hiding the addictive behavior from others; and several others (Indiana University). Therefore, based on the aforementioned statements, we can say that psychological addiction is a pathological condition of the mind, which is characterized by an excessive dependency or obsession on a certain object or action and ignoring the potential dangers of addictive behavior.
The physical aspect of an addiction is characterized with a continued use of certain substances even when significant problems related to their use develop (Wexner Medical Center). As a result, bodies of such addicts cannot tolerate without new doses of drugs, alcohol, etc. Since people with an addiction (substance dependence in particular) have little or no control over their obsessions (Medical News Today), physical addiction can be defined as a constant need to intake certain substances to satisfy one’s craving, even though this may be harmful for the addict, who often is unable to control the craving.
Combining the two definitions that we have distilled so far, we can define the phenomenon of addiction as a mind pathology characterized by an obsession of certain actions, objects, or substances, which brings addicts temporary satisfaction while often being harmed by them, but over which they have little or no control.
