borderline personality disorder

In the complex landscape of mental health, Borderline Personality Disorder (BPD) stands out for its profound impact on emotions, relationships, and self-image. Often misunderstood and stigmatized, BPD not only challenges those who live with it but also intertwines intricately with other issues, notably substance abuse. This co-occurrence amplifies the struggles faced by individuals and complicates the path to recovery and well-being.

Understanding Borderline Personality Disorder (BPD)

Borderline Personality Disorder (BPD) is a mental condition characterized by instability in moods, behavior, self-image, and functioning. People with BPD experience intense episodes of anger, depression, and anxiety that can last from a few hours to days. They may have trouble controlling their emotions and thoughts, engage in impulsive and often reckless behavior, and have unstable relationships.

Signs and Symptoms of BPD

Key symptoms of BPD include:

  • Efforts to avoid real or perceived abandonment
  • A pattern of unstable relationships
  • Distorted self-image
  • Impulsivity in potentially self-damaging behaviors like substance misuse
  • Self-harming behavior and suicidal threats or behavior
  • Intense and variable moods
  • Chronic feelings of emptiness
  • Intense anger or difficulty controlling anger
  • Feelings of dissociation

The Intersection with Substance Abuse

Substance abuse is commonly seen in individuals with Borderline Personality Disorder. About 78% of adults with BPD develop a substance use disorder or addiction at some point in their lives. The use of substances, be it alcohol, prescription drugs, or illegal drugs, can temporarily relieve the emotional distress characteristic of BPD, but this relief is often short-lived. Substance abuse exacerbates the symptoms of BPD, increasing risks such as suicidal behavior, affective instability, and interpersonal issues.

Contributing Factors and Consequences

  • Gender Differences: There are variances in comorbid BPD and substance use disorders with men often outnumbering women in substance abuse.
  • Childhood Trauma: A common variable for both disorders is childhood trauma, which can lead to neurobiological vulnerabilities making individuals more susceptible to the effects of substance abuse.
  • Substance Use as Self-Medication: Individuals with Borderline Personality Disorder may use psychoactive substances like opiates, cocaine, or alcohol to self-medicate the overwhelming effects of emotional distress.
  • Increased Risks: The combination of substance abuse and BPD leads to a greater risk of suicidal behavior, shorter abstinence phases, and more frequent treatment dropout.

Treatment Approaches

Effective treatment requires an integrated approach that addresses both BPD and substance abuse. Therapists with expertise in both conditions are crucial. Treatments may include psychopharmacotherapy, skills training, and sociotherapy. It’s also important to address any underlying trauma and to develop coping mechanisms for managing emotional distress.

Seeking Professional Help

Early intervention is key. Treatment for BPD and substance abuse should be hierarchical and simultaneous. It is important for individuals with BPD and comorbid substance use disorders to seek and maintain treatment under professional guidance.


Understanding the intricate relationship between BPD and substance abuse is essential for effective treatment and care. Recognizing the signs and seeking early professional help can significantly improve outcomes for individuals dealing with these co-occurring disorders.
