Researchers from the Center for BrainHealth at The University of Texas at Dallas have found evidence that the effects of chronic marijuana use may depend on when a person started smoking pot and for how long.
For the study, which was published in the journal Proceedings of the National Academy of Sciences on Nov. 10, Francesca Filbey from the School of Behavioral and Brain Sciences at the University of Texas at Dallas, and colleagues involved 48 adult marijuana users who started to use weed when they were between 14 and 30 years old.
The participants smoked pot thrice a day on average; most admitted that they had been using weed for 10 years. Some participants reported they had been using marijuana for 30 years.
The researchers had the participants take an IQ test and undergo MRI scans. They then compared the results with those of 62 individuals who were nonusers and found that in cognitive tests, marijuana users had lower IQ compared with those who did not smoke pot.

Pot heads swear this isn’t true.
Stupid people smoke it or does it make you stupid? Guess that depends on who you ask.
Beat me to it.
Prolonged use of any intoxicant will have harmful side effects. Whether it is the currently mostly legal alcohol, or the currently mostly banned pot, or some prescription item.
Some people smoke pot to forget emotional pain and that is generally counterproductive.
People need to get their spirituality right, or they will always find a way to zonk themselves to the ill.
I know, and they’re only fooling themselves.
I don’t think Obama indulges now. If he did, he probably wouldn’t be so stinking antagonistic. (Whatever else one can say about the vices/virtues of the weed.)
How true. That’s a great example. Take away the teleprompter from this guy and you have proof of what pot can do to the cognitive skills of heavy dope user.
Just because there is a statistical correlation among study participants, does not prove there is a direct cause. There was a study last month that “proved” men who have had at least 20 sex partners have a lower chance of prostate cancer. That correlation does NOT prove that sleeping with 20 women will directly reduce cancer risks but the papers skewed headlines to get more readers.
There are also many studies that show schizophrenics are 2-3 times more likely to smoke cigarettes and their brain scans are different. It does NOT prove cigarettes causes schizophrenia or any brain changes.
There has not been a SINGLE before-after brain scan study showing any long-term difference in pot users. There has not been a SINGLE study of twin humans or animals showing ANY difference at all. Even when subjected to amounts of pot only possible in a lab. The only thing we have are MRI scans showing brains NOW and this does not prove any CHANGE.
IMO, we see the IQ differences in studies because the only people who would admit to using pot for a study are the low paid, low-IQ types. Professionals are often prosecuted for using this plant and do not wish to have a record anywhere admitting to use.
Makes you stupid. I have a friend who was a top 10 HS student, National Merit Scholarship winner and dean’s list in college. He started smoking while on campus. 40 years later he is stocking shelves at a grocery store and deals daily with deep paranoia. It has been sad to watch his descent into his present existence. When you can just talk to him the bright young guy of an earlier time occasionally comes through, but sadly those days are fewer and fewer anymore. And yes it is physically addictive.
I am the rare exception. Nearly killed me.
Oh, I agree. Alcohol also makes people stupid and perhaps quicker. I never understand, however, why pot heads seem to think the physical harm of alcohol is supposed to make pot smoking seem okay.
More than I think?
But of course. I can’t think.
Probably all that pot I smoked back in high-school...
Go to any skate park in America and see if you can carry on a conversation with a toked up skater that doesn’t include him saying duuuuude a million times.
Keep telling yourself that as you light up another doobie. Most of my alcoholic friends don’t have a drinking problem either just ask them.
If you don’t mind my asking, how did it nearly kill you?
