Symptoms of Substance Use Disorders

Substance use disorder is a complex brain disease characterized by compulsive use of addictive substances. Symptoms not only include physiological dependence but also involve comprehensive changes in psychological, social functioning, and behavioral patterns. Early identification of symptoms is crucial for preventing disease progression, but many individuals miss the opportunity for treatment due to lack of awareness of these symptoms.

The symptoms of this disorder can be divided into three main categories: physiological dependence, psychological dependence, and social dysfunction. Patients often exhibit increased tolerance, withdrawal reactions, and compulsive use behaviors, which tend to worsen as the disease progresses. Understanding the stage-specific changes of these symptoms can help family members and healthcare professionals intervene early.

Early Symptoms and Signs

Early symptoms typically manifest as subtle behavioral changes that are easily overlooked. Patients may begin to show the following signs: a shortened duration of euphoria after substance use, requiring higher doses to achieve the same effect (tolerance). Additionally, they may react defensively or deny their usage when questioned by others, saying things like "I still have control" or "I only use occasionally."

Changes in social circles are another important sign; patients may gradually distance themselves from old friends and turn to groups with similar usage habits. Common physiological signs during this period include a brief alertness after use, followed by noticeable fatigue or anxiety responses. It is noteworthy that these early symptoms are often accompanied by emotional fluctuations, such as depression or irritability after use.

Common Symptoms

Physiological Dependence-Related Symptoms

Typical manifestations of physiological dependence include withdrawal reactions and increased tolerance. When patients stop using substances, they may experience the following symptoms:

  • Tremors, sweating, rapid heartbeat, and other autonomic nervous system disturbances
  • Gastrointestinal discomfort such as nausea, diarrhea, or abdominal pain
  • Severe cases may present with hypertension, seizures, or hallucinations

Psychological and Behavioral Symptoms

Psychological symptoms include intense cravings for the substance, which become central to daily life beyond physiological needs. Patients may exhibit behaviors such as:

  • Hiding their use, such as obtaining prescriptions from different pharmacies or claiming to have lost their medication
  • Neglecting work or family responsibilities to obtain substances
  • Losing interest in previously enjoyed activities, with focus entirely shifted to substance use

Disease Progression and Symptom Changes

In the early stages, symptoms may appear intermittently, such as only using during stressful periods. As the disease advances, symptoms tend to become persistent and more severe. Increased tolerance leads to escalating doses, and patients may attempt unconventional methods such as injection or mixing multiple substances to enhance effects.

Social dysfunction worsens over time, with specific manifestations including:

  • Sharp decline in occupational performance, frequent absences, or job loss
  • Severe deterioration of interpersonal relationships, frequent family conflicts difficult to resolve
  • Legal issues such as illegal possession or sale of substances

In late stages, patients may experience cognitive impairments, including memory decline, reduced judgment, and loss of planning ability. These changes not only affect daily functioning but can also lead to self-destructive behaviors or life-threatening risks.

When to Seek Medical Help

Seek professional assistance immediately if any of the following occur:

  • Severe physical discomfort during withdrawal (e.g., severe tremors, hallucinations)
  • Significant increase in frequency or dosage of substance use
  • Inability to control substance use despite causing interpersonal, occupational, or legal problems

The following situations also warrant prompt evaluation:

  • Intense guilt about substance use but unable to stop
  • Repeated attempts to quit but repeatedly fail
  • Emergence of self-harm or suicidal tendencies

Even if severe physiological dependence has not yet developed, if daily life quality is affected, professional consultation should be considered. Early intervention can significantly improve treatment outcomes. It is recommended to undergo professional assessment through psychiatry or specialized addiction centers.

 

Frequently Asked Questions

What role does family support play in the treatment of substance use disorders?

Family support is crucial for treatment. Family members should avoid blame and instead communicate with empathy, helping the patient establish healthy routines and encouraging participation in professional treatment. Studies show that family involvement in treatment plans (such as family therapy) can improve patient compliance and reduce relapse risk.

Which non-pharmacological methods have been proven effective for substance use disorders?

Cognitive-behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR) are widely used. CBT helps patients identify thought patterns that trigger addiction, while mindfulness enhances tolerance to cravings. Support groups (such as Alcoholics Anonymous) also improve psychological resilience through peer sharing.

How should patients cope with relapse? Does it mean treatment failure?

Relapse is common in the treatment of substance use disorder and does not indicate failure. The key is to immediately reassess the treatment plan and adjust strategies, such as increasing counseling frequency or introducing alternative therapies. Research indicates that patients who promptly return to treatment have long-term recovery rates comparable to initial treatment success.

How do substitution therapies work in medication-assisted treatment?

Substitution therapy uses medications (such as methadone, buprenorphine) to alleviate withdrawal symptoms and reduce cravings. These drugs act on the same brain receptors as addictive substances but produce more stable effects without euphoria, thereby reducing illegal substance use. They should be combined with psychological therapy for long-term recovery.

What psychological issues are commonly associated with patients with substance use disorders, and how should they be addressed?

Common comorbidities include depression, anxiety, and borderline personality disorder. Treatment should follow a dual diagnosis approach, addressing both substance abuse and mental health issues simultaneously. For example, using anti-anxiety medications alongside addiction-specific cognitive therapy can more effectively improve overall mental health.
