Cannabis and Bipolar Disorder

This is a post about cannabis use in bipolar disorder. Most of the evidence from the papers I have cited below is negative. It says using cannabis can lead to an earlier onset of bipolar disorder. It says it can exacerbate manic and depressive symptoms.

There are a few reports that cannabis may help with mood, but generally a lot more negative findings. I would be very leery of using cannabis, THC or CBD until a lot more conclusive evidence that they help becomes available.

Among individuals with bipolar disorder, concurrent CUD (cannabis use disorders) were associated with earlier age of onset and greater annual number of bipolar episodes. ► Co-occurring CUD are associated with significant co-morbidities and a more severe course of illness among individuals with bipolar disorder.

While there are some positive effects of cannabis on anxiety and mood reported in people with bipolar, there are many more negative effects, see below.

Research with negative findings regarding marijuana use in bipolar treatment

Some researchers have actually found that marijuana use can make bipolar symptoms worse in some people. Examples of their studies include the following:

Triggering manic episodes and worsening symptoms

A review published in early 2015 found that using marijuana could make manic symptoms worse in a person with bipolar disorder. They also found that marijuana use could trigger a manic episode. In addition, the 2015 study above touting benefits to marijuana use, also found that it worsened manic or depressive symptoms in some people.

Higher rates of attempted suicide and early onset

According to another study from 2015, suicide attempt rates in people with bipolar disorder were higher in those who used marijuana than in those who didn’t use marijuana. The study also found that people who used marijuana were younger at bipolar disorder onset (when their symptoms first started) than those who didn’t use it. This is a concern, as doctors think that a younger age at onset of bipolar disorder causes worse symptoms throughout a person’s life. The effect of marijuana on early onset and suicide rates wasn’t clear however, researchers said.

While marijuana may help some people with bipolar disorder, these studies show that it could also cause problems for others with the condition.

Marijuana, bipolar disorder, and genetics

Research has also shown that the use of marijuana can affect people differently based on their genetics.

According to the NIDA, people who carry certain gene types are more likely to experience psychosis. For instance, people who have an unusual variation of the AKT1 gene are more likely to have psychosis, and the risk is higher if they use marijuana. Also, psychosis risks from adolescent use of marijuana have been linked with a genetic variation in the gene that controls an enzyme called catechol-O-methyltransferase (COMT).

If you have bipolar disorder and are considering using marijuana as a treatment, talk to your doctor about possibly testing for these or other genetic variations.

Let’s face it. Even those who don’t have to deal with bipolar disorder can experience a bad high. Pair that with the feelings and thoughts that those with bipolar disorder deal with, and you’ve got a dangerous combination.

Unfortunately for many, the risk of treating with weed may outweigh the good it can do.

In a 2015 study, scientists found that mania and depression symptoms could actually worsen if weed became part of a treatment plan. Moreover, the study found smoking a J or munching on an edible could actually bring on a manic episode that may not have been present before treating with weed.

While exacerbation of symptoms definitely might deter many from toking to treat bipolar, the reaction could be dependent on the individual and his/her tolerance.

Nevertheless, other studies have found a major side effects of treating bipolar with green. This 2015 study discovered an increased rate of attempted suicide in those with bipolar who consumed pot. The threat of these negative thoughts may be enough for anyone to lay down the pipe and seek other medications.

But even more so, studies have linked early onset bipolar disorder in younger people who use weed. And this news is alarming. Doctors have found that the earlier someone is diagnosed, the symptoms one experiences can be worse than in those who are diagnosed later.

Few positives reported like mood state cleared up in the short term with cannabis use. But mostly negative effects seen.

When performing studies of cannabis use for the treatment of bipolar disorder, researchers must consider the differences between consumption methods. Depending on the type of cannabis consumed, scientific findings may be skewed by errors in consistency from study to study. For instance, bipolar patients who smoke cannabis concentrates with extremely high THC levels are likely to experience more adverse mood responses than those smoking CBD rich strains of cannabis flower.

This is because THC is known to incite acute anxiety and paranoia in some consumers, while CBD is effective in mediating the negative effects of psychotropic symptoms. It’s also essential to recognise the type of strain being studied, whether it is sativa, indica or hybrid. Each will produce different results individually and on a larger scale. The lack of comprehensive scientific inclusion of different cannabis methods makes it difficult to maintain consistency across samplings.

THE CONCLUSION?

The takeaway from current research of cannabis on bipolar patients is that there simply aren’t enough compelling studies to say definitively if it can effectively treat bipolar patients. While it has been shown to spur symptoms of anxiety and mania, many patients use cannabis not as medication, but for their personal enjoyment when they are not experiencing an episode. Cannabis offers a wide range of medical implications and could very well be one of the keys to natural mental healthcare in the near future.

The role of cannabis in psychiatric illnesses has been an area of interest. Epidemiological studies have shown that as the frequency of cannabis abuse increases, so does the risk for a psychotic disorder such as schizophrenia.1 Studies have also shown that cannabis is the most commonly abused drug among those diagnosed with bipolar disorder.

Cannabis intoxication can lead to acute psychosis in many individuals and can produce short-term exacerbations of pre-existing psychotic diseases.3–6 Cannabis use also causes symptoms of depersonalization, fear of dying, irrational panic, and paranoid ideas, which coincide with acute intoxication and remitted quickly.

As our case report demonstrates, there are individuals who are otherwise healthy, with no genetic predisposition, who can be diagnosed with a psychiatric illness purely with cannabis abuse. This goes along with the first hypothesis that cannabis use causes psychotic symptoms in an otherwise healthy individual, which would not have occurred with abstinence. One would argue that someone who had a first episode psychosis with cannabis use is itself a risk factor for having a subsequent psychotic or mood disorder. These are the patients we should follow closely to help prevent from having long-term consequences secondary to cannabis abuse.

  1. That is ironic because just Monday my psychiatrist said CBD oil will be approved in November for seizures and that it would be good for me to use. I am bipolar 1. She said thc isn’t good for bipolar though. They come from the same plant but extracted differently.
