Further Evidence That Marijuana is a Poison

[Coup]

ScienceDaily (Feb. 3, 2009) ? Adolescents and young adults who are heavy users of marijuana are more likely than non-users to have disrupted brain development, according to a new study. Pediatric researchers found abnormalities in areas of the brain that interconnect brain regions involved in memory, attention, decision-making, language and executive functioning skills. The findings are of particular concern because adolescence is a crucial period for brain development and maturation.

The researchers caution that the study is preliminary and does not demonstrate that marijuana use causes the brain abnormalities. However, "Studies of normal brain development reveal critical areas of the brain that develop during late adolescence, and our study shows that heavy cannabis use is associated with damage in those brain regions," said study leader Manzar Ashtari, Ph.D., director of the Diffusion Image Analysis and Brain Morphometry Laboratory in the Radiology Department of The Children's Hospital of Philadelphia.

The study appeared early last month in the Journal of Psychiatric Research. The current research builds on previous work by Ashtari and colleagues, who used the same imaging technology to analyze normal brain development in adolescent subjects.
In the current study, working with child psychiatrist Sanjiv Kumra, M.D., now at the University of Minnesota, Ashtari and colleagues performed imaging studies on 14 young men from a residential drug treatment center in New York State, as well as 14 age-matched healthy controls. All the study subjects were males, with an average age of 19. The researchers performed the imaging studies at Long Island Jewish Medical Center.
The 14 subjects from the drug treatment center all had a history of heavy cannabis use during adolescence. On average, they had smoked marijuana from age 13 till age 18 or 19, and reported smoking nearly 6 marijuana joints daily in the final year before they stopped using the drug.

The study team performed a type of magnetic resonance imaging scan called diffusion tensor imaging (DTI) that measures water movement through brain tissues. "The abnormal patterns of water diffusion that we found among the young men with histories of marijuana use suggest damage or an arrest in development of the myelin sheath that surrounds brain cells," said Ashtari. Myelin provides a coating around brain cells similar to insulation covering an electrical wire. If myelin does not function properly, signaling within the brain may be slower.

Myelin gives its color to the white matter of the brain, and covers the nerve fibers that connect different brain regions. "Our results suggest that early-onset substance use may alter the development of white matter circuits, especially those connections among the frontal, parietal and temporal regions of the brain," said Ashtari. "Abnormal white matter development could slow information transfer in the brain and affect cognitive functions."
Ashtari added that the findings are preliminary. Among other limitations of the study, such as a small sample size, five of the 14 subjects with heavy cannabis use also had a history of alcohol abuse, which may have contributed an effect. Also, it is possible that the brain abnormalities may have predisposed the subjects to drug dependence, rather than drug usage causing the brain abnormalities.

"Further research should be done to investigate the relation between repeated marijuana use and white matter development," said Ashtari. "However, our work reinforces the idea that the adolescent brain may be especially vulnerable to risky behaviors such as substance abuse, because of crucial neural development that occurs during those years."
The National Institute of Mental Health provided grant support for this research. Ashtari's and Kumra's co-authors were Kelly Cervellione, of Jamaica Hospital Medical Center, Jamaica, N.Y.; John Cottone, of Zucker Hillside Hospital, Glen Oaks, N.Y.; and Babak A. Ardekani, of The Nathan Kline Institute for Psychiatric Research, Orangeburg, N.Y. Serge Sevy of Zucker Hillside Hospital also contributed to the project.

Marijuana destroys the brain cells rendering the people useless to the revolution. Keep your mind strong. it will make you much more effective in the revolutionary destruction of the bourgeoisie!

I wouldn't put that stuff within 1 mile of my body.

[arock10]

I heard marijuana was the leading cause of crunchy vibes man. true or false

[CaptainHowdy]

Great read, "instinctively" I always avoided marihuana...

[Blackamooka]

I don't do drugs of any kind, because I agree that a strong mind requires a strong body.

That said, you're smoking crack if you think there will ever be a revolution in the United States.

i don't think you have much worry from there in your mom's basement.

anything worth doing or ingesting is in some way or another, a poison. fat, meat, booze, foie gras, extreme sports, driving a sports car, whatever. no one gets out alive, enjoy it while you're still around.

that's why marijuana like alcohol and tobacco should be for adults only.

Also, they said HEAVY use of marijuana. Most people even in their youth that used marijuana never were "heavy" users. Heavy usage to me is being stoned more or less 24/7.

Oh and this gem is priceless

Ashtari added that the findings are preliminary.

I can't stand "studies" like these.

marijuana has detrimental effects on the adult brain as well.

Marijuana = Poison of the mind

so does everything else so what's the difference if its marijuana or one of the thousands of other things ranging from food to fabric softeners that cause cancer, death, "conditions" etc

this thread is for the benefit of those that don't know or refuse to believe that marijuana is harmful.

what the fuck

8char

[myneid]

during a double blind study that i did, weed made me awesome and much smarter!

[woj]

If you are heavy user of ANYTHING it will fuck you up... 6 joints per day is pretty much high 24/7...

[Spunky]

Ima going to smoke another reefer

[icymelon]

somehow I think in our life time we will see it legal and taxed. poison or life saver depending on your health situation

Whatever.

Kids and young adults shouldn't do drugs, anyway, only us old farts. We need 'em more.

Do you think marijuana should be legal?

I think all substances that are harmful to the minds of the people should be eradicated

[mikesinner]

It's obvious that marijuana is bad for you just like cigarettes are bad but sciencedaily isn't the type of site I'd want to get my info from.

[quiet]

yeah, i think we should all sit in a dark room (sunlight causes cancer), eat nothing but fruit and vegetables, drink nothing but water, not own a car, and do yoga. sounds like fun.

Wow great post so you mean drugs aren't good for kids? I had no idea. LOL.

Give a kid any kind of drug including aspirin or any other similar substance in large quantities and it will be bad or even disastrous, that's pretty much obvious to most people.

The revolution is NEVER coming. You might as well go ahead and cook yourself as a silent protest while becoming a pretty much useless member if society. Seriously, that will show them...

[marketsmart]

here come the articles as california gets close to a november vote...

on a side note: the stupidity level here continues to annoy me more and more everyday..

you fucking clown shoes read 1 article about 1 study and start repeating it as fact..

no wonder you are failing in business, you are too fucking stupid to do anything that requires your own though process...

I hear that it might cause you to eat an entire 20 piece chicken Mcnuggets. Scary!
