Diagnosing drug addiction requires realizing that there is a problem and seeking help. Alcohol and drug use are not always an indication of addiction, although drug use carries many health and social risks in addition to the danger of addiction. Once an individual has decided that they have a problem and need help, the next step is an examination by a healthcare professional.

Diagnosing drug addiction requires assessment by a mental or medical health professional. A total diagnosis often includes assessment by multiple professionals, such as a general practitioner, psychologist, and psychiatrist. People should undergo testing and assessment not only for drug addiction but also other conditions that could contribute to or affect the addiction, such as mental health disorders and medical conditions.

In a formal addiction treatment program, the diagnostic process often takes place during the initial assessment. After that assessment, which may include medical tests in addition to an interview with the client, initial diagnoses may be made. These diagnoses may be modified as the treatment process starts.

Can Addiction Be Treated Successfully?

While the term “addiction” does not appear in the DSM, it is generally viewed as a severe substance use disorder. According to the Substance Abuse and Mental Health Service Administration (SAMHSA) [1], addiction is described as a chronic, relapsing disorder characterized by compulsive drug seeking, continued use despite harmful consequences, and long-lasting changes in the brain. It is considered both a complex brain disorder and a mental illness.

Addiction is a treatable, chronic disorder that can be managed successfully. Study shows that combining medications ( if needed ) with behavioral therapy, is the best way to ensure success for most patients. The combination of behavioral interventions and medications to treat alcohol and drug abuse is known as medication-assisted treatment. Treatment approaches must be personalized to address each patient’s drug use patterns and drug-related medical, environmental, psychiatric, and social problems. This is according to the Substance Abuse and Mental Health Service Administration (SAMHSA) [2].

Criteria In Diagnosing Drug Addiction

Diagnosis is the process of identifying and labeling specific disease conditions. The symptoms and signs used to classify an ill person as having a disease are called diagnostic criteria. Diagnostic criteria and classification systems are useful for making clinical decisions, estimating disease pervasiveness, understanding the roots of the disease, and developing scientific communication.

Diagnosis also may serve a variety of administrative purposes. When a person is suspected of having a substance use disorder, diagnostic procedures are needed to eliminate “false positives” (for example, people who seem to have the disorder but who really do not) and borderline cases. The need for uniform reporting of statistical data, as well as the generation of prevalence estimates for epidemiological research, often requires a diagnostic classification of the client.

Process In Diagnosing Drug Addiction

prescription drugs
Diagnosing drug addiction and comorbid mental disorders is complex because it is often difficult to disentangle overlapping symptoms.
  • The first step in diagnosis relies on a family member, friends, or the person struggling with addiction themselves confirming a need for treatment.
  • This can usually be the most challenging step and might sometimes involve either a personal, or group intervention if the person suffering from alcohol or drug addiction is not aware of the extent of the problem.
  • The individual with suspected drug or alcohol addiction visits a primary care physician or a family doctor, who may then refer them to an addiction or rehabilitation specialist.
  • The doctor will ask questions about frequency of use, impairment of daily living, and whether the use of drugs or alcohol is increasing, and how the pattern of use is affecting important social, work, school, or other functional areas.
  • The doctor will also ask about withdrawal symptoms which may have happened at times when the person tried to decrease or stop use.
  • They will perform a physical examination, conduct a toxicology screening, and run some blood work to assess overall well-being. This helps to decide if medical treatment is needed.

Criteria For Substance Use Disorders

In 2013, the American Psychiatric Association (APA) updated the Diagnostic and Statistical Manual of Mental Disorders (DSM), replacing substance abuse and substance dependence with a single category: substance use disorder, with three subclassifications such as mild, moderate, and severe. In addition, the symptoms of substance use disorder fall into four major groupings: impaired control, social impairment, risky use, and pharmacological criteria (i.e., tolerance and withdrawal). 

DSM 5 is the standard classification of mental disorders used for clinical, research, policy, and reimbursement purposes in the United States and elsewhere. Therefore, it has widespread importance and influence on how disorders are diagnosed, treated, and investigated. [3]

The DSM 5 allows clinicians to define how severe or how much of a problem the substance use disorder is, depending on how many symptoms are identified, happening within a 12-month period. Those who have two or three criteria are considered to have a “mild” disorder, four or five are considered “moderate,” and six or more symptoms, “severe.” The diagnostic criteria are as follows:
