Link between pot, psychosis goes both ways in kids

By Andrew M. Seaman | Reuters - 6 hrs ago

NEW YORK (Reuters Health) - Marijuana (cannabis) use may be linked to the development of psychotic symptoms in teens - but the reverse could also be true: psychosis in adolescents may be linked to later pot use, according to a new Dutch study.

"We have focused mainly on temporal order; is it the chicken or the egg? As the study shows, it is a bidirectional relationship," wrote the study's lead author Merel Griffith-Lendering, a doctoral candidate at Leiden University in The Netherlands, in an email to Reuters Health.

Previous research established links between marijuana and psychosis, but scientists questioned whether pot use increased the risk of mental illness, or whether people were using pot to ease their psychotic symptoms, such as hallucinations and delusions.

"What is interesting in this study is that both processes are going on at the same time," said Dr. Gregory Seeger, medical director for addiction services at Rochester General Hospital in upstate New York.

He told Reuters Health that researchers have been especially concerned about what tetrahydrocannabinol (THC), the active property in pot, could do to a teenager's growing brain.

"That's a very vulnerable period of time for brain development," and individuals with a family history of schizophrenia and psychosis seem to be more sensitive to the toxic effects of THC, he said.

A 2010 study of 3,800 Australian teenagers found that those who used marijuana were twice as likely to develop psychosis compared to teens who never smoked pot (see Reuters Health article of March 1, 2010 here:).

But that study also found that those who suffered from hallucinations and delusions when they were younger were also more likely to use pot early on.

CHICKEN v. EGG

For the new study, published in the journal Addiction, the researchers wanted to see which came first: pot or psychosis.

Griffith-Lendering and her colleagues used information on 2,120 Dutch teenagers, who were surveyed about their pot use when they were about 14, 16 and 19 years old.

The teens also took psychosis vulnerability tests that asked - among other things - about their ability to concentrate, their feelings of loneliness and whether they see things other people don't.

Overall, the researchers found 940 teens, or about 44 percent, reported smoking pot, and there was a bidirectional link between pot use and psychosis.

For example, using pot at 16 years old was linked to psychotic symptoms three years later, and psychotic symptoms at age 16 were linked to pot use at age 19.

This was true even when the researchers accounted for mental illness in the kids' families, alcohol use and tobacco use.

Griffith-Lendering said she could not say how much more likely young pot users were to exhibit psychotic symptoms later on.

Also, the new study cannot prove one causes the other. Genetics may also explain the link between pot use and psychosis, said Griffith-Lendering.

"We can say for some people that cannabis comes first and psychosis comes second, but for some people they have some (undiagnosed) psychosis (and) perhaps cannabis makes them feel better," said Dr. Marta Di Forti, of King's College, London, who was not involved with the new research.

Di Forti, who has studied the link between pot and psychosis, told Reuters Health she considers pot a risk factor for psychosis - not a cause.

Seeger, who was also not involved with the new study, said that there needs to be more public awareness of the connection.

"I think the marijuana is not a harmless substance. Especially for teenagers, there should be more of a public health message out there that marijuana has a public health risk," he said.

Griffith-Lendering agrees.

"Given the severity and impact of psychotic disorders, prevention programs should take this information into consideration," she said.

 I wish people would believe these studies.But too many are in denial because they want so much to be able to smoke pot ( or eat it)

Any thing that alters the mind is bound to have some type of negative impact on some.  

Pot is legal in my State.  I get it.  I understand it.  But if I catch my kids with it or high, my position on it will not change.  No matter their age.

 I think any sort of mind altering drug (manmade or natural) can be determental to young minds.  I also agree that it could help "calm the demons" in kids that have naturally occurring psychosis.

IMO its a logical conclusion ...shrug

I think this is really interesting, thanks for sharing. It is late and I should be in bed, so I might not be reading this properly, but it doesn't sound like they reached the conclusion that pot use in teens causes mental illness.Yes, they confirmed a correlation, but they haven't determined causation.

I am not saying teens should use pot or that I would approve of dd doing it when she is a teen.

I just dont think this study has shown anything other than a very interesting link between mental illness and teens using pot. It doesn't show whether the pot causes psychosis, or teens suffering from both diagnosed and undiagnosed mental illness self medicate using pot. I'm really interested in follow up research to see if they can determine why the link is there.

Again, I'm not saying that it's okay for teens to use pot. I'm not a pot user either, if that matters. I just dont think this is proof that pot harms teens in that way.

This.

This study is saying teens who smoke pot may later have psychosis, and people who have psychosis may have smoked pot as teens.

Okay.

Some teens that are in sports may be athletic when they are older. Some athletes may have played sports as teens.

Maybe I'm tired and not getting it... But I'm really not understanding.

Here's what is funny to me.  Teens today are more medicated than ever before.  I'm talking doctor prescribed medications.  And we are also seeing mental illness rise at a disturbing rate, along with many other neurological disorders. 

Meanwhile, marijuana can treat over 3 dozen things that people are currently being treated for with prescribed medications, all of them with mile long lists of side effects, death being one for just about all of them, and many of these things are things that teens are being treated for, and marijuana carries none of those nasty side effects.  If these teens ate a few special brownies now and then, they would probably have far fewer problems, than if they continued taking their legal drugs.

ETA: sorry, hit send before I was finished. 

Then there's the fact that this study shows that kids who have psychosis problems when they are young are more likely to use pot, probably to relieve their symptoms, which is how it should be used.  It also talks about kids in this study who started pot and then got psychosis, but doesn't really address underlying issues... as in the psychosis may have already been there to begin with, and was going to happen anyway.  So really, this study proves absolutely nothing, one way or the other.

It didn't even prove a correlation.  It's basically junk, in that it did nothing to prove anything one way or the other, although it is not junk in the sense that information about an aspect of the study can be taken in other directions by other researchers.  It didn't do anything to further the idea that pot causes psychosis, or that psychosis causes pot use.

The post says: "Also, the new study cannot prove one causes the other."  This study did absolutely nothing to confirm one way or the other whether pot useage increases psychosis, or that psychosis increases pot useage.  It's basically more fear mongering, with a few "oops, we didn't prove anything whatosever but that doesn't meant that there COULDN'T be a direct link." Did you even read the whole thing?
