Recognizing the symptoms of SUD is crucial for early intervention, effective treatment, and promoting recovery. Find out more about the key signs and symptoms of Substance Use Disorder.

Understanding Substance Use Disorder (SUD)

Substance Use Disorder encompasses a range of substance-related issues, including addiction and dependence. SUD is diagnosed based on specific guidelines provided in the DSM-5 or Diagnostic and Statistical Manual of Mental Disorders and can affect individuals regardless of age, gender, or background.

Common Symptoms of SUD

  1. Craving: An intense desire or urge to use the substance regularly, leading to compulsive behavior.
  2. Loss of Control: Difficulty controlling the amount or frequency of substance use, often resulting in consuming larger amounts than intended or unsuccessful attempts to cut down or quit.
  3. Tolerance: The need for increased amounts of the substance to reach the desired effects due to developing tolerance over time.
  4. Withdrawal Symptoms: Experiencing physical or psychological withdrawal symptoms when attempting to reduce or stop substance use. Withdrawal symptoms of SUD vary but may include nausea, sweating, anxiety, irritability, insomnia, or seizures.
  5. Neglecting Responsibilities: Prioritizing substance use over responsibilities at work, school, or home, leading to neglect of duties and obligations.
  6. Continued Use Despite Consequences: Persisting in substance use despite negative implications such as health problems, relationship difficulties, legal issues, or financial problems.
  7. Loss of Interest: Diminished interest in activities or hobbies that were once enjoyable or important due to preoccupation with substance use.
  8. Isolation and Secrecy: Withdrawing from social activities, isolating oneself from friends or family, and engaging in secretive behavior related to substance use.
  9. Mood Changes: Mood swings, irritability, agitation, anxiety, depression, or personality changes associated with substance use.
  10. Risk-Taking Behavior: Engaging in risky or dangerous behaviors while impaired, such as driving impaired, taking risks with sexual activity, or participating in criminal activities to obtain drugs.

Recognizing Different Types of Substance Use

Substance Use Disorder can involve various substances, each with its own set of symptoms and effects:

Alcohol Use Disorder (AUD)

Symptoms may include increased alcohol tolerance, frequent alcohol cravings, withdrawal symptoms like tremors or sweating, and continued alcohol use despite negative consequences.

Drug Use Disorders

These can include opioid use disorder, stimulant use disorder, and others. Symptoms vary based on the specific substance but often involve cravings, tolerance, withdrawal symptoms, and compulsive drug-seeking behavior.

Prescription Medication Misuse

Misusing prescription medications, such as opioids, sedatives, or stimulants, can lead to SUD symptoms similar to other drug use disorders.

Seeking Help for Substance Use Disorder

If you or someone you know is experiencing symptoms of Substance Use Disorder, it’s essential to seek professional help and support. Treatment options may include:


Detox is a process in which an individual stops using substances while under medical supervision to manage withdrawal symptoms safely.


Participating in therapy sessions, whether individual or group, to address underlying issues, identify triggers, learn coping strategies, and prevent relapse.

Medication-Assisted Treatment (MAT)

Medications prescribed in a medical or treatment setting can help manage cravings while also reducing withdrawal symptoms. Other prescribed medications may be used to block the effects of certain substances.

Support Groups

Participating in support groups for peer support and ongoing recovery efforts.

Holistic Approaches

Incorporating holistic therapies such as mindfulness practices, exercise, nutrition counseling, and stress management techniques to support overall well-being.
