Substance Abuse vs. Dependence: What’s the Difference?
Stigma often surrounds the use of terms such as addiction, dependence, and substance abuse. In recent years, related medical terminology has been changed and clarified. The Diagnostic and Statistical Manual of Mental Disorders (DSM), the official guide for diagnosing behavioral disorders, previously had the classifications “substance abuse” and “substance dependence.” Those were long criticized for a variety of reasons, including the fact that the difference between substance abuse and dependence was not clear, substance dependence was often confused with physical dependence, and the word “abuse” had negative connotations.
Things changed with the 2013 publication of the manual’s fifth edition, the DSM-5, which combines substance abuse and substance dependence into a single category called substance use disorder, which has levels ranging from mild to severe.
Classifying Substance Use Disorders
The DSM-5 establishes 11 criteria as the basis that addiction counselors and other professionals use in assessing the extent of a patient’s substance use disorder. Severity is characterized as follows:
|Number of Criteria Present||Severity|
|2 or 3||Mild|
|4 or 5||Moderate|
|6 or more||Severe|
The 11 criteria apply to various substances. As an example, here’s how addiction counselors would apply them to patient assessment for alcohol use disorder (AUD):
1. Lack of Control – Alcohol is frequently consumed in larger quantities or for a longer time than the patient intends.
2. Unsuccessful Attempts to Quit – The patient wants to control his or her alcohol intake, but each attempt to do so has failed.
3. Significant Time Investment – A significant amount of the patient’s time is spent pursuing and using alcohol or recovering from its use.
4. Cravings – The patient experiences a regular, powerful urge to use alcohol.
5. Impact on Daily Obligations – Alcohol use has impaired the patient’s ability to fulfill work or personal duties.
6. Use Continues Despite Conflicts – The patient has experienced ongoing social problems that are exacerbated by alcohol use, but continues his or her pattern of use, regardless.
7. Abandonment of Activities – Significant recreational and professional activities have been ignored or reduced in frequency as a result of alcohol use.
8. Physical Harm – The patient has consumed alcohol in situations that are dangerous or that pose a threat to physical health.
9. Use Despite Understanding of Consequences – Alcohol use persists despite the patient’s knowledge of a physical or psychological problem that’s likely caused by alcohol.
10. Tolerance – The patient has developed either a need for greater amounts of alcohol to reach his or her desired level of intoxication, or has observed a reduced effect when using the usual amount of alcohol.
11. Withdrawal – Alcohol is taken to relieve symptoms of withdrawal, which include (among others) depression, fatigue, mood swings, anxiety, and irritability.
