What indicates a substance use disorder?

Direct Answer

A Substance Use Disorder (SUD) is a diagnosable condition characterized by an impaired ability to control the use of a substance. This impaired control continues despite negative social, occupational, psychological, or physical consequences. The diagnosis of an SUD is based on specific criteria outlined in diagnostic manuals, not solely on the frequency of use.

This does not mean that every instance of substance use, even if regular, constitutes an SUD. An SUD involves a pattern of symptoms indicating that a person continues to use a substance despite experiencing significant problems related to its use. The presence of an SUD is determined by a qualified professional using established diagnostic standards.

Common Misunderstandings

Some believe daily use of a substance automatically means an addiction. This is incorrect; frequency of use is one factor, but impaired control and negative consequences are central to a diagnosis.

Another misunderstanding is that only physical dependence equals an SUD. An SUD encompasses a broader range of symptoms beyond just physical withdrawal. Psychological dependence and harmful patterns of behavior are also key indicators.

A third misconception is that personal willpower is sufficient to overcome an SUD. An SUD is a complex condition involving brain changes, and recovery often requires professional support, not just desire or willpower.

In Practice

A substance use disorder is identified through a set of criteria. These criteria include continuing substance use despite negative impacts, craving the substance, and an inability to cut down or control use. It also involves taking more of the substance than intended or spending a lot of time obtaining, using, or recovering from its effects.

Symptoms are categorized across mild, moderate, and severe levels. The number of criteria met determines the severity. For example, meeting two to three criteria typically indicates a mild SUD, while meeting six or more indicates a severe SUD. These criteria are defined in diagnostic manuals such as the Diagnostic and Statistical Manual of Mental Disorders (DSM).

In California, the Department of Health Care Services (DHCS) outlines requirements for SUD treatment services that align with these diagnostic criteria. In Florida, the Florida Certification Board recognizes criteria established by the American Society of Addiction Medicine (ASAM) for levels of care. The Ohio Chemical Dependency Professionals Board also adheres to similar diagnostic standards for credentialed professionals assessing SUDs.

What This Does NOT Mean

This does not mean that occasional or moderate substance use is inherently an SUD. The criteria focus on a problematic pattern of use, not just the act of using.

This does not include self-diagnosis based on anecdotal experience. A formal diagnosis requires assessment by a trained professional following standardized diagnostic criteria.

This does not guarantee that someone experiencing negative consequences from substance use will automatically receive an SUD diagnosis. The full array of diagnostic criteria must be evaluated by a professional.
