No. The personality disorder may cause one to become addicted to substances and thus bringing out overwhelming negatives in the disorder, but it does not cause the disorder. Though, everybody's brains are wired differently.
Borderline Personality Disorder and Addiction | Dual Diagnosis
Quote:
Those who suffer from BPD are seen as highly manipulative, dependent and dramatic, but mental health professionals understand that this behavior arises as a dysfunctional way to cope with overwhelming fear and emotional pain. The pain, emotional instability and impulsive behavior of borderline personality disorder place these individuals at risk of drug or alcohol abuse.
The relationship between BPD and addiction is a volatile one. The use of drugs and alcohol aggravate some of the more dangerous symptoms of BPD, most notably, rage and depression. Those who have BPD are more likely to engage in drug or alcohol consumption as an attempt to numb the pain of their fear of abandonment.
