Borderline Personality Disorder, or BPD, is a challenging mental health condition that affects how people manage emotions, relationships, and impulses. With cannabis becoming more widely used and accepted, many people with BPD are wondering: how does cannabis impact this disorder? Can it help? Or could it make things worse?
This article dives into what we know so far about cannabis and BPD — exploring both the potential benefits and the risks, based on recent research and expert insights.
What Is Borderline Personality Disorder?
Borderline Personality Disorder popularly known as BPD is more than just mood swings. It is a complex mental health condition marked by emotional instability, impulsivity, and difficulties in interpersonal relationships. It may also be called emotionally unstable personality disorder. People with BPD have unstable moods and can act recklessly. They also have a hard time managing their emotions consistently. People with BPD often struggle with feelings of emptiness, fear of abandonment, and a shaky sense of self. Many experts believe BPD develops from a mix of genetics, life experiences, and especially early trauma like abuse or neglect.
Cannabis and Mental Health: A Complicated Mix
Cannabis contains compounds like THC and CBD that interact with the brain’s endocannabinoid system — a system that helps regulate mood, stress, and emotional responses. Because these areas are often out of balance in BPD, some people think cannabis might help.
But the reality is complicated. Cannabis can sometimes calm anxiety and mood swings, but it can also make symptoms worse, depending on the person, the type of cannabis, and how it’s used.
Could Cannabis Help Manage BPD Symptoms?
Cannabis is known to help patients with a wide variety of health concerns and conditions, including different mental health issues. According to recent studies,there’s some promising evidence that cannabis might ease certain BPD symptoms. For example, a small group of patients using cannabis-based products reported feeling less anxious and impulsive, and better able to handle mood swings. This might be because cannabinoids like CBD help “tone down” the brain’s emotional response, giving some temporary relief.
Since no other pharmacological treatment for BPD has yet to achieve long-term success for those seeking relief from symptoms associated with BPD. Some experts think cannabis could become part of future treatments for BPD.
But There Are Real Risks, Too
On the flip side, cannabis isn’t risk-free — especially for people with BPD. THC, the part of cannabis that gets you “high,” can sometimes increase anxiety, paranoia, and impulsivity. For someone with BPD, these effects can make emotional ups and downs even more intense.
There’s also the risk of cannabis-induced psychosis — a scary condition involving hallucinations and paranoia. People with mental health conditions like BPD are more vulnerable to this, especially if they use cannabis heavily or start young.
Plus, many people with BPD struggle with substance abuse, including cannabis. Using cannabis regularly can sometimes lead to dependency and make it harder to recover from BPD symptoms.
Why Do People With BPD Use Cannabis?

Many people with BPD turn to cannabis to self-medicate in order to calm racing thoughts, ease anxiety, or manage emotional pain. Research shows that people with BPD are more likely to use cannabis impulsively when they’re feeling distressed.
But this coping strategy can backfire. One study found that people with BPD who use cannabis don’t respond so well to therapy, and their symptoms may not improve as much as those who don’t use cannabis.
The Bigger Picture: Genetics and environment
Looking at the bigger picture of genetics and environment, recent research suggests that cannabis use and Borderline Personality Disorder (BPD) may be connected through shared genetic and social factors. For instance, individuals who have a genetic predisposition to conditions such as schizophrenia or depression might have an increased risk of developing BPD if they use cannabis regularly.
This means cannabis use might not just worsen symptoms but it could even play a role in how BPD develops in some people.
What Do Experts Say?
Most mental health professionals agree that while cannabis might provide short-term relief for some people with Borderline Personality Disorder (BPD), it is not a cure and carries significant risks. Experts emphasize that cannabis use should always be approached with caution and under strict medical supervision to minimize potential negative side effects and the risk of developing dependency.
Recent clinical observations suggest that cannabis-based medicinal products (CBMPs), particularly those containing cannabidiol (CBD), may help reduce symptoms such as anxiety, mood instability, and impulsivity in some patients with BPD or emotionally unstable personality disorder (EUPD). In a small case series, six out of seven patients reported noticeable symptom improvement after a month of treatment with CBMPs, with few or no adverse effects. This rapid onset of symptom relief contrasts with traditional psychiatric medications, which often take weeks to show benefits. Such findings hint at the potential for cannabinoids to serve as an adjunctive treatment, especially during acute emotional crises when fast-acting interventions are needed.
However, experts also caution that THC—the psychoactive component of cannabis—can exacerbate symptoms like paranoia, anxiety, and impulsivity, which may worsen the course of BPD. There is a documented risk of cannabis-induced psychosis, particularly in individuals with pre-existing mental health vulnerabilities. Given that substance use disorders frequently co-occur with BPD, cannabis use can complicate treatment and recovery, sometimes leading to a cycle of self-medication and increased symptom severity.
Mental health professionals stress that cannabis should never replace evidence-based psychological therapies, such as dialectical behavior therapy (DBT), which remain the cornerstone of BPD treatment. Instead, cannabinoids might be best viewed as a supplementary tool to help manage symptoms temporarily while patients engage in long-term therapeutic work.
Finally, experts call for more rigorous, long-term research to better understand the safety, efficacy, and optimal dosing of different cannabis compounds in BPD. Larger clinical trials are needed to clarify which patients might benefit, how to minimize risks, and how cannabis-based treatments can be integrated safely into comprehensive care plans.
Conclusion
Cannabis and BPD have a complicated relationship. For some, cannabis can offer relief from anxiety and mood swings. For others, it can worsen symptoms and lead to more serious mental health problems.
If you or someone you love has BPD and is considering cannabis, it’s important to talk with a healthcare professional who understands both the disorder and the effects of cannabis. With careful guidance, it might be possible to find a balance that supports emotional well-being without causing harm.
