(CNN)Marijuana is notorious for slowing certain cognitive functions such as learning, memory and attention span (maybe that's why they call it "dope"?). But new research in young people suggests that these cognitive effects, while significant, may not persist for very long, even among chronic users.
The meta-analysis, published Wednesday in the journal JAMA Psychiatry, combines data from 69 previous studies that look at the effects of heavy cannabis use on cognitive functioning in adolescents and young adults. It found that those young people who identified as heavy marijuana users scored significantly lower than non-users in a variety of cognitive domains such as learning, abstraction, speed of processing, delayed memory, inhibition and attention.
"There have been a couple of meta-analyses done in adult samples, but this is the first one to be done specifically in adolescent and young adult samples," said Cobb Scott, assistant professor of psychiatry at the Perelman School of Medicine at the University of Pennsylvania and a lead author of the study.
"We looked at everything from learning and memory to different aspects of executive functioning such as abstraction ability," Scott said. "And we basically showed that the largest effects -- which was around a third of a standard deviation -- was in the learning of new information and some aspects of executive functioning, memory and speed of processing."
But when the researchers separated the studies based on length of abstinence from marijuana use, the difference in cognitive functioning between marijuana users and non-users was no longer apparent after 72 hours of marijuana abstinence. That could be an indication "that some of the effects found in previous studies may be due to the residual effects of cannabis or potentially from withdrawal effects in heavy cannabis users," Scott said.

72 Hours so basically it never ends since they have to stop first.
“I wouldnt recommend it though for people who are already mentally dull. “
that’s the origin of the fear of pot.
My father, oldest brother, and youngest brother were all alcoholic. Youngest brother died a horrendous death as a result of alcohol and substance abuse.
So, yes I have.
After all night partying, took my SATs one Saturday morning, after boning up in the parking lot, and again at the break.
Got into MENSA on the scores. My fellow pothead friends thought that was funny as $hit. Me, too.

Did you tell your son or daughter this the night before they took their tests? If the answer is no, then why are you bragging about it here?
LOL
“72 Hours so basically it never ends since they have to stop first.”
Those who smoke every day are constantly diminished.
But that’s from their sober baseline.
If they have a baseline IQ of 140, they are still way smarter than the average Joe. If their baseline IQ is 90, they go through life retarded and not knowing it.
“So, yes I have.”
That’s sad sh!t.
My condolences.
I’ve had several family members die as a result of alcohol addiction too.
Thank God they never killed anyone but themselves.
“All those folks inventing cutting edge tech that changed everyones life are high as a kite.”
You’re implying that users get smarter or more creative under the influence. The study shows nothing of the sort.
What it says is that within 72 hours of usage cognitive capacities are impaired and that after 72 hours AT BEST they returns to normal. But if you’re a constant user you’re constantly and SIGNIFICANTLY impaired!
“It found that those young people who identified as heavy marijuana users scored significantly lower than non-users in a variety of cognitive domains such as learning, abstraction, speed of processing, delayed memory, inhibition and attention.”
If you owned a software company would you knowingly hire a pothead?
Really good news here. Our yoots dont need to smoke pot while driving in order to enjoy that comfortable buzz (freeway driving in particular can be very aggravating) they cant just toke up before and it will last and last and last.
Very difficult to obtain a base line to start from.
“Youre implying that users get smarter or more creative under the influence. “
Absolutely NOT!
Everyone is some degree of dumb on pot. And significantly diminished.
No, I would not hire a chronic user if I could parse them out from the occasional user. But I would not hesitate to hire an occasional user.
Since it’s impossible to parse them out, I would judge them on performance alone.
I would have rather thanked God that my brother never started drinking, smoking, or ingesting in the first place.
Sorry about your family members, too.
Alcohol and drugs are usually the subject of sophomoric responses and immature humour until you personally see the human devastation carried in their wake.

I have a nephew that burned his liver at age 34.
He’s sober now and trying to prove he’s worthy of a transplant.
How the hell does one burn out their liver that quick? He was an amazingly poor drinker, every day was a binge drunk.
“Absolutely NOT!”
Well you did state that...
All those folks inventing cutting edge tech that changed everyones life are high as a kite.
Ummm....oh no, another test! By the self appointed morality police!
Let’s see...First, whether I have kids or not, and if I do, what I tell them is most definitely none of your business. The fact that you would ask such a thing with ease makes me seriously question your motives. Your hidden ones, not the nice high horse (hah) judgemental one ya got there and so freely display. And I’m being nice.
As for the rest:
A. It wasn’t bragging, and
B. You missed the point (obviously).
Oh, and
C. I smoked weed with my mom. Probably yours, too.
heh
Au contraire, mon frere.
This research and CNNs summary completely ignore the existing research that indicates there is long term damage to the brain of developing brains. This has been confirmed with a lack / loss of white matter in the brain. Pot turns kids permanently into idiots.
In her demented mind.
She’s still white. Always was. Always will be.
