BPD and Addiction: Understanding Borderline Personality Disorder and Substance Abuse

What Is Borderline Personality Disorder?

Borderline personality disorder is a serious mental illness characterized by unstable interpersonal relationships, intense emotional episodes, and difficulties with self-image.[2] People with BPD experience extremely strong emotional experiences which may vary quickly and unpredictably, leading to impulsive behavior and challenges with forming and maintaining stable relationships. BPD often develops in early adulthood and influences how someone perceives themselves and others, often leading to intense, highly unstable relationships marked by rapid shifts between extreme closeness and deep conflict 

Many experience intense anger, self-harm, or express suicidal ideation. Mood swings can happen quickly, often changing within hours, and can be triggered by a seemingly minor event or feeling rejected. Such emotional reactions can feel overwhelming and difficult to manage, affecting a person’s ability to function day-to-day and interact with others.

Signs and Symptoms of Borderline Personality Disorder

Borderline personality disorder presents through a range of distinct symptoms that affect emotions, behavior, relationships, and self-image. While everyone experiences these symptoms differently, mental health professionals look for specific patterns that persist over time and significantly impact daily functioning, including:

Criteria for diagnosing BPD includes:

• Intense fear of abandonment that often leads to frantic efforts to avoid either real or perceived rejection.
• Unstable and intense relationships that are characterized by alternating between idealization and devaluation, a term known as “splitting”
• An unstable sense of self-image and sense of self.
• Dangerous impulsive behavior in at least two areas, such as spending, sex, substance use, or reckless driving.
• Self-destructive behavior, including suicidal threats and gestures, or self-harm
• Intense mood swings lasting from a few hours to several days.
• Chronic feelings of emptiness and difficulty finding meaning or purpose in life
• Difficulty controlling anger that often results in intense outbursts followed by shame or guilt
• Stress-related paranoia
• Severe dissociative symptoms.

To meet the diagnosis for borderline personality disorder, someone must show five or more of the above criteria.[3]

Borderline Personality Disorder and Addiction

Living with both borderline personality disorder and addiction creates unique challenges that can intensify symptoms of both conditions. The relationship between BPD and substance use is complex, as many people turn to substances to cope with symptoms like overwhelming emotions, relationship difficulties, and identity struggles that are common in BPD. While this pattern of self-medication can bring relief, it is only temporary, and the substance use eventually worsens BPD symptoms over time.[4] This creates a cycle of emotional discomfort, substance use, and worsening symptoms that escalate substance use.

BPD and addiction also influence each other in other ways:

• Emotional dysregulation contributes to increased substance use during intense mood swings.
• Impulsivity symptoms can lead to dangerous binge use of substances.
• Relationship instability may trigger both substance use and BPD symptoms.
• Identity disturbance often results in using substances to feel more confident or stable.
• Fear of abandonment can increase relapse risk during relationship conflicts.
• Self-destructive tendencies may manifest as high-risk substance use behaviors.

Because BPD and SUD often co-occur, they require a unique form of treatment that addresses each disorder simultaneously under the same plan, rather than separate or even parallel treatment. Traditional addiction treatment methods may need modification to account for the emotional intensity and relationship challenges of BPD. Addiction recovery takes time and is unpredictable so support from mental health professionals who are familiar with each client’s needs can help promote stability to provide a solid base for continued healing over time.

Risk Factors for BPD and Addiction

There is no single reason for developing either BPD or addiction. 

Risk typically arises out of a combination of biological, emotional, relational and environmental influences that shape an individual’s response to stress, emotions, and the way they relate to others. For some people, BPD symptoms and substance use begin to overlap when substances become a way to manage emotional pain, numbness, impulsive urges, or fear of abandonment.

There are a variety of risk factors that can contribute to an increased possibility of developing BPD, addiction, or the combination of both, including:

• Family history of either other mental health disorders or substance use disorders
• History of childhood trauma, neglect, abuse, or unstable caregivers
• Difficulty regulating intense feelings
• Impulsive behaviors or engaging in high-risk activities
• Chronic stress or repeating conflicts in relationships
• Co-occurring mental health disorders such as depression, anxiety, post-traumatic stress disorder (PTSD),or attention deficit or hyperactivity disorder (ADHD)
• Early exposure to substances
• Using substances as a method for coping with emotional pain.

These risk factors don’t necessarily mean someone is destined for BPD or addiction. But they do help us understand why some people may be more vulnerable than others. Understanding your risk factors in treatment can also help the clinician create a treatment plan that addresses more than just substance use. It will provide an opportunity to identify your triggers, learn healthier ways of coping with difficult situations, and understand how certain emotional states or stressful relationships can increase the urge to use substances.

How BPD Symptoms Can Affect Addiction Recovery

Addiction recovery can seem more unstable for someone with BPD because shifts in moods, relationships, and stress can all change so quickly. For example, if someone has a disagreement with a loved one, feels rejected by someone who has been supportive in the past, or feels shame after a setback, it can cause an immediate increase in cravings as well as make relapse feel more likely at that moment.

It doesn’t necessarily mean that recovery is impossible. It means that recovery will require additional support for the emotional intensity that often accompanies BPD such as distress tolerance strategies, crisis planning strategies, improved communication skills, and better methods for dealing with urges when those urges begin to overwhelm. 

Dialectical Behavioral Therapy (DBT) in particular, has proven very helpful. It was developed specifically for treating borderline personality disorder and helps to build skills needed to help people with the disorder stay grounded during intense emotional episodes, reduce impulsivity,  and develop healthier relationships.[5]

Recovery from BPD and addiction may also involve learning how to recover from setbacks in their lives without immediately turning them into evidence that they have failed at treatment. Progress with BPD or addiction is rarely consistent or steady. But developing an effective treatment plan provides those with either disorder many useful ways to address difficult emotional experiences, relationship instability, or cravings during periods of high emotional intensity.

Statistics About BPD and Addiction

Research shows a significant connection between borderline personality disorder and addiction. 

Studies indicate that 2.7% of adults meet the diagnostic criteria for BPD, and 78% of that number will develop a substance-related disorder during their lifetime.[6] 

Approximately 50% of people with BPD struggle with an addiction to at least one substance, with alcohol being the most common.[7] 

25% of people in substance use disorder treatment also meet the criteria for BPD.[8]

Research shows that people with opioid, cocaine, and alcohol use disorders have the highest rates of co-occurring BPD.[9] 

BPD affects between 0.7 percent and 2.7 percent of the general population, but in clinical settings, the rates of those with BPD increase substantially, with a 6% in primary care, 11 to 12% in outpatient psychiatric clinics, and rising to 22 % for psychiatric inpatients.[10] 

While women show slightly higher rates in the general population at 3% compared to 2.4% for men, the gender disparity becomes more pronounced in outpatient psychiatric settings, where women represent over 70% of BPD cases.[11]

People with BPD have higher treatment dropout rates, have an increased risk for self-harming or suicidal behavior, and have shorter abstinence periods.[12] This underscores the importance of targeted therapeutic interventions that consider both the personality disorder and addiction together.
