Substance use disorder is a complex condition characterized by an unhealthy pattern of substance use, which can vary in intensity from mild to severe. Substance use disorder, sometimes abbreviated to SUD, is the clinical descriptor for addiction.
Although SUD is incurable, all substance use disorders can be effectively treated. If you suspect that you or a loved one may be developing an addiction, seek assistance promptly – substance use disorder is a progressive condition that benefits from timely intervention.
This guide highlights the most common substance use disorder signs and symptoms to help you determine the existence or extent of a problem with addiction.
What is Substance Use Disorder?
Substance use disorder is a chronic mental health condition characterized by a maladaptive pattern of substance use that leads to distress and impairs various aspects of life.
Substance use disorder occurs on a spectrum. Individuals may experience mild, moderate, or severe manifestations. SUD is a chronic and relapsing brain disorder often marked by an overwhelming compulsion to use substances regardless of adverse outcomes, the development of increased tolerance to the substance, and the occurrence of withdrawal symptoms upon cessation.
People may develop an addiction to one substance like alcohol or opioids, or they may abuse multiple substances – meth in combination with alcohol and prescription painkillers, for instance. Polysubstance abuse is an especially dangerous form of drug abuse.
Substance use disorder profoundly affects physical and mental well-being, relationships, and overall quality of life. Additionally, it poses a significant risk to life itself. Recognizing the signs of substance use disorder and seeking prompt assistance can streamline the journey towards recovery and healing.

Symptoms of Substance Use Disorder
The revised edition of American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) outlines the following substance use disorder symptoms:
- Consumption of the substance in greater quantities than intended or for longer than planned.
- Unsuccessful attempts to reduce or discontinue substance use.
- Significant time spent acquiring, using, and recovering from substance use.
- Strong cravings use the substance.
- Failure to fulfill important personal and professional responsibilities due to substance use.
- Continued substance use despite experiencing persistent social and interpersonal problems as a result.
- Giving up or reducing participation in important activities as a result of substance use.
- Engaging in substance use in physically dangerous situations.
- Continued substance use despite a psychological or physical issue being triggered or worsened by it.
- Development of tolerance – either needing higher amounts of the substance to achieve the desired effect or experiencing reduced effects with the same amount.
- Withdrawal symptoms, either characteristic of the substance or using the substance to relieve or avoid withdrawal symptoms (such as alcohol or benzodiazepine withdrawal).
These DSM criteria help mental health specialists diagnose substance use disorder. Diagnosis of involves assessing the presence of DSM-5 substance use disorder symptoms and determining the severity of the disorder.
- Mild addiction: Presence of 2 to 3 criteria.
- Moderate addiction: Presence of 4 to 5 criteria.
- Severe addiction: Presence of 6 criteria or more.
Additionally, substance use can trigger various symptoms and behaviors that include:
- Cognitive impairment and confusion.
- Neglecting or losing interest in maintaining a regular, healthy eating pattern.
- Withdrawal from social interactions with friends and family.
- Engaging in risky activities without considering the consequences.
- Sudden, noticeable changes in behavior or mood.
- Responding with denial or hostility if confronted about substance use.
- Decreased concern for personal appearance compared to previous levels of grooming and self-care.
- Exhibiting secretive behavior in an attempt to conceal substance use.
- Using addictive substances even when alone, without the presence or influence of others.
An awareness of these additional signs and symptoms of substance use disorder can help determine the appropriate course of action – typically seeking professional help or staging an intervention.

What is The Treatment for Substance Use Disorder?
Treatment for substance use disorder involves a comprehensive and individualized approach to address the unique needs of each person. The goal of treatment is to help individuals overcome their problematic substance use, regain control over their lives, and improve their overall well-being.
There are various treatment options available, and the most effective approach depends on variables such as the type and severity of the substance use disorder, the individual’s specific circumstances, and their preferences. Some common components of addiction treatment include:
- Detoxification: This is usually the first step in the treatment process and involves safely managing withdrawal symptoms as the body clears the substances from its system. Medical supervision and support may be necessary during this phase. Detox addresses the issue of physical dependence. Ongoing treatment in an inpatient or outpatient rehab is typically required to tackle the psychological aspect of substance use disorder.
- Behavioral therapies: These therapies focus on modifying harmful thoughts, attitudes, and behaviors related to substance use. CBT (cognitive-behavioral therapy), MI (motivational interviewing), and CM (contingency management) are examples of evidence-based approaches that can help people in recovery develop coping strategies, enhance motivation for change, and prevent relapse.
- Medications: In the case of alcohol use disorders and opioid use disorders, FDA-approved medications may be prescribed to aid in the treatment of substance use disorders. Medications can help manage withdrawal symptoms, reduce cravings, or block the effects of certain substances. The specific medications used will depend on the substance involved and individual needs.
- Support groups: Participating in support groups, such as 12-step programs like AA (Alcoholics Anonymous) or NA (Narcotics Anonymous), can provide valuable peer support, encouragement, and a sense of community for individuals in recovery.
- Counseling and therapy: Individual counseling or therapy sessions can address underlying issues contributing to substance use, improve mental health, and provide support during the recovery process. Family therapy may also be beneficial to address family dynamics and help rebuild relationships.
- Holistic approaches: Complementary and alternative therapies, such as mindfulness meditation, yoga, art therapy, and exercise, can complement traditional treatment methods by promoting relaxation, self-awareness, and well-being.
Recovery from substance use disorder is a lifelong process, and treatment may need to be adjusted or continued over an extended period. The support and involvement of family, friends, and a strong social support network can also play a significant role in the success of treatment and long-term recovery.
