I think the "cannabis user" and "non-user" are the same person except the slice used as "cannabis user" is slightly more anterior where the hippo campus is less thick. You can tell by the third and lateral ventricles and thalamus.

ITS LEGIT : "Those who smoked cannabis regularly had on average a 12% smaller hippocampus, the part of the brain which is thought to be involved with emotion and memory, and a 7% smaller amygdala, which plays a role in regulating fear and aggression.

For the study, researchers imaged the brains of 15 cannabis smokers and 16 individuals who did not use the drug. The scientists, led by Murat Yücel at the University of Melbourne and colleagues at the University of Wollongong, said scans on larger numbers of people were needed to confirm the extent of the effect.

"Although modest use may not lead to significant neurotoxic effects, these results suggest that heavy daily use might indeed be toxic to human brain tissue," the scientists report in the journal Archives of General Psychiatry.

Cannabis users also fared worse in tests of verbal memory and were more likely to have low-level symptoms of psychotic disorders such as schizophrenia and mania."

delusioned potheads, "Regarding marijuana, the Amen Clinics, which represents more than 1,000 neuropsychiatric clinicians in the United States, have claimed that regular marijuana use leads to the degeneration of the prefrontal cortex and the temporal lobe (where the hippocampus is located) as noted in SPECT scans.

A 2001 article, "Brain SPECT in Neurology and Psychiatry", by Edward Camargo in The Journal of Nuclear Medicine discusses SPECT scans in more detail.

The Amen Clinics have compiled data from roughly 40,000 sources over nearly 30 years."

Correlation ≠ causation

Is it not possible that those with brain structures that are more underdeveloped than normal are susceptible to poor coping mechanisms like heavy cannabis use?

It has already been shown that some ADHD brains are underdeveloped in some areas and that those with ADHD are significantly more susceptible to illicit substance use, abuse, and dependence.

This guys is on to something.

I'd be interested to see MRIs of the brains of people before and after smoking weed for various amounts of time.

Really an MRI isn't as useful as something like an IQ test, reaction time test, etc, though. Structural changes in the brain can easily cause functions to be assumed by other parts of the brain.

[K++ !!7tArEbO1L9o No.1382569]

HOLY CRAP REALLY? So you're saying that if I put a substance into my body that alters the chemistry in my brain so that it functions differently that over a long period of time there may be harmful effects? Weeeeelllll hOOOLLLYYYYSHHIIITTT

Next you guys will be telling me that inhaling substances such as "smoke" after a long period may cause lung damage and cancer.

Fuck, maybe even the SUN isn't safe anymore right?

I find it silly that potheads say pot has no long-term effects and I find it equally silly that people try to throw studies in faces of potheads like "TOLD YOU SO".

Anything you do that causes something to function outside of normal parameters is going to fuck it up eventually. Hell, even normal function tends to degrade things.

YOU ARE FUCKED NO MATTER WHAT

I think the reason they do this is because public information about cannabis is ridiculously biased to one side or the other.

Of course it alters your brain, as does everything you do. If you put on a blindfold for a year it'll alter your brain, too.

What I actually wanted to say is, keep it in moderation. Because SMOKE WEED EVERYDAY turns most people into useless potheads. Some seem to be able to handle it, though, but that's only 5 out of 100 or so.

No doubt that even if pot makes you stupid, there are still potheads who are "smarter than the average joe."

Perhaps it causes an average of 10 points of IQ lost, perhaps zero. Either way, not *everyone* who uses it would have an IQ of 90, even if that were the average.

I had an IQ test when I was 16 again when I was 17... My mom was convinced I was a genius... Averaged 145.

I started smoking when I was 18, from about 19-21 I was smoking no less than 5 times a day, high 24/7. I only smoke every once and a while now, still getting good grades at college and scoring higher than 140s on all the fake online IQ tests.

take another real IQ test, same standard deviation

the online ones are a good comparison between people (IE you get 145, your friend gets 130, odds are you are smarter than your friend), but the exact number they give can be pretty far off. Also a lot of them are purely pattern recognition tests, which are really not a valid measure of IQ alone, even if properly centered and deviated.
