Could Marijuana Help Bipolar Disorder?

Could marijuana help bipolar disorder?

Marijuana has been shown to benefit a number of physical health problems, ranging from multiple sclerosis to type 2 diabetes, inflammatory bowel disease, and cancer pain. But what about mental disorders? A new study found that use of cannabis (marijuana) could be helpful in improving certain neurocognitive functions in people who have bipolar disorder, a condition diagnosed in such notable individuals as Jesse Jackson Jr., Jane Pauley, and Sinead O'Connor.

How marijuana could help bipolar disorder

There's a tendency to believe that use of marijuana leads to mental health problems, and indeed there have been studies indicating that cannabis can trigger bipolar disorder in susceptible individuals or lead to early psychosis. On the other hand, research has also shown marijuana to be helpful in managing post traumatic stress disorder (PTSD) and schizophrenia.

In this new study, a collaborative effort between researchers at The Zucker Hillside Hospital in Long Island, Mount Sinai School of Medicine, and the Albert Einstein College of Medicine, New York, investigators explored the impact of marijuana on the cognitive performance of 50 individuals with bipolar disorder I who had a history of cannabis use compared with 150 people with the mental disorder and no history of cannabis use. All the participants were similar in racial background, age, and educational level, as well as when bipolar disorder was diagnosed.

Individuals who had a history of marijuana use showed "significantly better neurocognitive performance, particularly on measures of attention, processing speed, and working memory" than did the study participants who did not use marijuana, according to the researchers.

This finding is similar to the one reached by researchers at the University of Oslo and reported on in Psychological Medicine in 2010. In that study, 133 patients with bipolar disorder and 140 with schizophrenia were evaluated, along with their use of marijuana.

The Oslo investigators found that use of marijuana among bipolar disorder subjects was associated with improved neurocognitive function, but that this was not true for schizophrenia patients. Bipolar patients who used marijuana showed good focused attention, verbal fluency, logical memory learning, and memory recall.

Bipolar disorder
The National Institute of Mental Health defines bipolar disorder, which is also referred to as manic-depressive illness, as a brain condition that causes individuals to experience unusual and severe fluctuations in energy, mood, activity level, and their ability to conduct day-to-day tasks. There are four basic types of bipolar disorder.

Bipolar I disorder, which is the one evaluated in the current study, is mainly defined as experiencing manic (overly joyful or overexcited state) or mixed episodes (manic mixed with feeling extremely sad or hopeless) that last at least seven days, or experiencing severe manic symptoms that require hospitalization. People with bipolar II disorder shift back and forth between but do not suffer with full-blown manic or mixed episodes. Cyclothymic disorder is a mild form of bipolar disorder, and bipolar disorder not otherwise specified (BP-NOS) is characterized by symptoms that don't last long enough or symptoms are too few to meet the criteria of bipolar I or II.

The authors of the latest study concluded that their findings could indicate that use of marijuana "may have a beneficial effect on cognitive functioning in patients with severe psychiatric disorders," although they also "may be due to the requirement for a certain level of cognitive function and related social skills in the acquisition of illicit drugs." Further research into the impact of marijuana on bipolar disorder and other mental health conditions is warranted.

I have had a lot of disorders and ive tryd everthing all kinds of medication.I have done better with how i feel and deal with things day2day dutys.My sleep is better and my eating is alot better...I really wish that a real chance for marijuana to help bipolar and other mental problems....It has helped me and i feel and can see a big difference in pill and pot....I WILL NEVER TAKE PILLS AGAIN...Marijuana is the only thing that truely has helped....
Weed is the only thing that has helped me cope with my past. That and therapy. Unfortunatly weed isnt previlant here where I live. But Im moving soon to a place where is is much more previlant and I can Smoke a bowl. It helps with my moodswings. Keeps me happy. and It keeps my social life alive because I had trouble keeping friends with my mood swings. Thank GOD for cannabis.
Agree totally. I think there are a lot more of us out their that don't need a scientific study to tell us that Marijuana is a Godsend. But it is a nice affirmation. I do think that marijuana is harmful to young people.....saps them of their motivation, memory retention, and inhibits their maturing process during those years that the brain is still forming (to 21 yrs old) but I'm sure there are still some cases where mj may help a young person who is suffering.
ts the goverment !!!!! someone with lots of money and plenty of power should do something about it !!! soon its gonna be to late !!!!! the people will fight back and we will win !!!!!!!!!!!!
i know for a fact it help i have been bi polar sence i was like 17 years old i am now 33 i smoke to handle my mood swings one min you can be great and the next your pissed at the world so when i fill it comeing on i same one or a bowl i am great . the feds need to know it is not judt to get hi it is for day to day life......# allforfreeingthegreen
Right on, (Anonymous) I was diagnosed "Bipolar / borderline personality disorder" around 1996 and I have been "lab ratted" to death! I have used "pot" to level out my mood swings for many years... However, I believe just as in all things, moderation is key! It is hard for me to not smoke it all day, however I have learned how to implement a regimen that I must strictly follow, and only use it to alleviate my symptoms. I have found that THC helps me more than any other "man made / manufactured" drug that is known to treat our disorder.... Lithium really had a insignificant effect on me as well! They need to legalize Marijuana world wide, for medicinal prepossess at the very least !
When I found out that I was b polar the doc put me on lithium. That wasn't quite working so came along Lamictil worked better than lithuim alone. I started smoking pot again and does take the edge off. My main consern is later in life does it cause phychoisis? I guess I'll find out later in life.
