Is medical marijuana bipolar treatment safe and effective? These common questions can be explained by exploring the relationship between marijuana and bipolar disorder.

Marijuana is the most commonly abused drug in America. Almost 70 percent of people who have bipolar disorder use cannabis during their lifetime, but can the use of marijuana treat mental health conditions? Is medical marijuana bipolar treatment safe and effective? These common questions can be explained by exploring the relationship between marijuana and bipolar disorder.

Can Marijuana Help Bipolar Disorder?

Many people wonder, “Can marijuana help with bipolar disorder?” Bipolar disorder is a mental illness that affects a person’s mood, energy levels and overall behavior. When someone has bipolar disorder, they tend to struggle with mania, which is brief periods of high energy and elevated mood, followed by bouts of depression, oversleeping and increased irritability.

Why Some People Use Marijuana for Bipolar Disorder

Bipolar disorder can feel overwhelming, but it is treatable which leads people to ask, “Can marijuana treat bipolar disorder?” Currently, there are no clinical studies that prove that marijuana can treat bipolar disorder. However, some people still attempt this treatment method.

Several anecdotal reports state that marijuana helps bipolar disorder. Marijuana essentially slows down the brain, which is why people with bipolar disorder may choose cannabis to help alleviate stress, anxiety and manic symptoms. Cannabis may seem like a good alternative to prescription medications that prove ineffective. According to interviews conducted by Psychiatry Advisor, several patients of a California marijuana dispensary reported that cannabis helps reduce the frequency of mood swings, racing thoughts and feelings of dread, making their daily life more manageable.

Why Marijuana Use May Not Help Bipolar Disorder

Marijuana does not fully treat bipolar disorder. The instances of marijuana treating bipolar disorder are few, and may not reflect most peoples’ experiences with bipolar disorder. More research must be done to prove whether marijuana is a safe and reliable treatment for this condition.

Existing studies on the relationship between marijuana and bipolar disorder conclude that marijuana use may contribute to worsened depressive and manic symptoms. Data from the Journal of Affective Disorders states that among people with bipolar disorder, marijuana use is associated with both early onset of manic periods and more frequent depressive episodes.

Many medical professionals dissuade people from using marijuana to treat bipolar disorder as it is not a safe and reliable medicine for everyone. “It can complicate the management of bipolar disorder by virtue of causing mood instability and psychosis in certain patients with bipolar disorder,” said psychiatrist Girish Subramanyan in an interview with Psychiatry Advisor. “Moreover, it’s not uncommon for me to see patients with bipolar disorder relapse into mania with recent cannabis use.”

One of the most concerning issues with combining marijuana and bipolar disorder is self-medication. Many people who use marijuana to treat bipolar disorder self-medicate without a doctor’s guidance. Self-medication with any drug for any condition, including marijuana and bipolar disorder, may not work and could be life-threatening. “‘Self-medicating’ is an extremely serious concern for our population,” says mental health journalist John McManamy. “Co-occurring substance abuse can effectively turn treatable bipolar into untreatable bipolar.”

Medical Marijuana and Bipolar Disorder

Americans continue to debate the safety and effectiveness of medical marijuana. Some people point out the lack of research on medical marijuana and bipolar disorder. Other people believe that anecdotal evidence is proof enough and believe that medical marijuana for bipolar disorder is a useful treatment method.

Recent research shows that chemicals called cannabinoids in marijuana may have antidepressant and sedative effects for people with bipolar disorder. These qualities may make medical marijuana bipolar treatment seem like a good choice, but there are also many reports of people who have experienced adverse side effects from marijuana, which could impact bipolar disorder symptoms.

For people who live with bipolar disorder, marijuana use can cause panic, hallucinations, feelings of depression or delusions. Because these can all be symptoms of bipolar disorder, medical marijuana and bipolar disorder may not be the safest combination. Additionally, the THC component of marijuana activates the amygdala, the part of the brain that controls fear. When the amygdala is affected by a drug like marijuana, someone can experience feelings of anxiety and paranoia.

Can You Get Medical Marijuana for Bipolar Disorder?

Current medical marijuana laws in most American states say that only a few physical and mental health conditions qualify for medical marijuana treatment. According to a report from 2017, bipolar disorder is not considered a qualifying condition for medical marijuana in any state. This ruling may change as research develops on marijuana, bipolar disorder and alternative medicine.

The consensus about medical marijuana for bipolar treatment is that using marijuana to treat this condition without a medical professional’s guidance is not recommended. Ultimately, there are too many unknown factors with marijuana use and no scientific evidence that it can treat bipolar disorder. One of the safest approaches a person can take is getting help from a clinician experienced in treating bipolar disorder.

Does Marijuana Cause Bipolar Disorder?

Some people may ask, “Can marijuana cause bipolar disorder?” According to research, it’s largely unlikely to do so. Although marijuana cannot cause bipolar disorder, its use can cause significant problems for someone with bipolar disorder.

Marijuana’s effects on bipolar disorder may include:

  • Making bipolar disorder symptoms worse: Marijuana use can induce feelings of mania, paranoia and, in some cases, psychosis.
  • More frequent depressive episodes: For someone with bipolar disorder, marijuana use can lead to overwhelming depressive episodes. After the effects of marijuana wear off, depressive symptoms can worsen.
  • Less adherence to a medication regimen: If someone uses marijuana regularly, the person may be less inclined to take their prescribed medicine. Skipping or forgoing necessary pills can be extremely dangerous or even deadly if the person experiences suicidal thoughts without their medication.
