Marijuana Use Leads to Earlier Psychosis, Bipolar Disorder

2011-02-07 18:16

Individuals who use marijuana may develop psychosis nearly 3 years earlier than people who do not indulge in cannabis use, according to a new study to appear in the June print issue of the Archives of General Psychiatry. Another new study notes that regular marijuana use may also trigger bipolar disorder in vulnerable individuals.

Marijuana use linked to earlier mental health problems

The National Institute on Drug Abuse notes that in 2008, a total of 25.8 million Americans age 12 and older had abuse marijuana at least once in the year before they were surveyed. According to the new study in Archives of General Psychiatry, more than 16 million Americans use marijuana regularly, and for some users this could have an effect on psychotic illness.

In fact, authors of the new study note “there is little doubt about the existence of an association between substance use and psychotic illness,” and that investigations have shown “more substance use, especially cannabis use, among people with a diagnosis of a psychotic disorder.”

Psychotic disorders are severe mental conditions that cause abnormal perceptions and thinking and are characterized by hallucinations and delusions. Types of psychotic disorders include schizophrenia and delusions disorder.

Comments some topics are taboo then? Narrow-minded approaches to an open debate regarding medical marijuana can never be the right way. I´m not impressed.
It really is just a study report. There is no opinion in this article. Plus, the last sentence reads: "The results highlight the potential dangers associated with marijuana use and need to be investigated further." It is not a biased article at all.
It has also been proven through trial and error in case studies, that indica cannabis helps quell the mania, while sativa helps alleviate the depression in Bi-Polar cases. It's most often a case by case basis, and for some people, it works. I find this research to be a bit biased.
I agree with your comment about it often being a case by case basis, but I just report it. --D. Mitchell
Yes, but the point is your article is extremely biased. You make it sound like it's just marijuana use that is setting off psychosis. But then you slip in there that it's marijuana "and other substances". Not to mention the fact that you can't prove these children weren't self-medicating without doing a long-term study.
This stuff causes people to become psychotic later in life. I know -- I smoked all through 8th grade. I stopped after I started high school because luckily I thought the stoners were losers at that point. After my third year of college at Stanford, in the summer, I became psychotic and have had a problem with depression and psychosis and mild mania ever since. I have been able to maintain euthymia (normal mood for only 1 1/2 to 2 years). There is no history of psychosis or psychosis spectrum disorders in my family. I am positive that smoking pot at such a young age ruined my life and my potential -- I had a full academic scholarship to Stanford -- and was unable to complete it. Parents -- do your children a favor and warn them!!
Kids don't smoke herb then develop mental illness , they smoke because they are self medicating the symptoms of there un-diagnosed disorder. I am speaking through personal experience.
The patients may have had early onset bipolar disorder and attempted to self-medicate.
