Experienced Marijuana Consumers Exhibit Virtually No Change In Cognitive Task Performance After Smoking
Experienced marijuana consumers exhibit nominal changes in cognitive performance after inhaling cannabis, according to clinical trial data published online this week in the journal Pharmacology, Biochemistry, and Behavior.
Investigators at Columbia University in New York and the San Francisco Brain Research Institute assessed acute marijuana-related effects on cognitive functioning in 24 volunteers who reported consuming the drug at least 24 times per week.
Researchers determined that participants' overall performance accuracy on episodic memory and working memory tasks "was not significantly altered by marijuana."
Authors concluded: "The present findings show that smoked marijuana produced minimal effects on episodic and spatial working memory of near-daily smokers. The overall response accuracy on the word recognition and working memory tasks was unaffected by marijuana, although smoked marijuana did increase the amount of time participants needed to complete these tasks.
"This pattern of effects is consistent with results previously reported by other researchers studying the acute effects of marijuana on cognitive performance of regular users. ... The finding ... stands in contrast to previous findings in occasional smokers who showed reduced accuracy on these same tasks after marijuana. ... The observation that frequent users' response accuracy is not altered after marijuana smoking to the same extent it is for infrequent users ... suggests that near-daily marijuana smokers may have developed tolerance to some marijuana-related behavioral effects."
For more information, please contact Paul Armentano, NORML Deputy Director, at: paul@norml.org. Full text of the study, "Neurophysiological and cognitive effects of smoked marijuana in frequent users," will appear in Pharmacology, Biochemistry, and Behavior.

Super Stoners !
a broken watch doesn;t lose any more time than it already did
a super stoner can't get much stupider than they already are
this is a study reported by NORML-
the National Organization to Reform marijuana laws
and its one more piece of questionable evidence
to show how drugs don;t .. uh.. well, uh,, they sort of do but
... well hardly... uh well.. its all just a prohibitionist lie
Super Stoners!!! Really?
Its amazing how poor your analogies are...a broken watch really??? I would like to point out that NORML did not conduct the study merely reported it. And it is apparent from your use of the non-word "stupider" that maybe you have been catching a contact...Oh wait let me guess your a pig...why else would you visit this site regularly to bash people that believe and understand things you do not want to understand or are not able too. Ps. NORML does not promote the legalizaton of all drugs just marijuana. Almost all famous musicians including all the ones you probably listen to smoke or have smoked marijuana...what does that say about them? Or our presidents?Or all the other extremely successful people that are far more intelligent than you that smoke marijuana? What will it take for people like you too understand...must Jesus himself come down from the heavens and verbally condone its use? Would that suffice? Either way, marijuana will be legal in this country and you are already surrounded by "super stoners" so live with it they are not hurting you. I am confident that you will make no intelligent defense or your arguments or your statements, you will just seek to immaturely call names. Stupider LOL
Broken Watch yes
Let me know when the world condones your cannabis addiction
or makes a single gesture towards changing the drug laws
in your favor-- like never, and you already suspect that
Till then, you are a commuter riding on the stupid bus
Broken Watch Yes!!
Thank you for proving me right!!! You couldn't answer any of the question only say I "ride the stupid bus". Oh and heres your gesture "mr.stupider"; 14 states allow Medical Marijuana and legalization is to be on 2 state ballots. So how's that for a gesture of condonation. By the way, Portugal decriminalized ALL DRUGs and they have half the drug use, twice the amount of people who seek voluntary treatment and a quarter of the crime. So say what you will you Narcotics agent...there will be a special place for people like you in the after life. After all, when the Germans SS and gestapo had to imprison and kill their fellow germans they were "just doing there job". Remember these are humans you are talking about REAL PEOPLE...But I know you are one of those people that give a child molester 7 years in prison and someone who smoke a plant 8 years... happens all the time. P.s. its kind of hard to worry about addiction(1st when caffeine is more addictive) when you have Colon Cancer and you are battling for your life...so keeping riding the bus of ignorance and cold-heartedness...I hope you don't get sick one day and need cannabis,b/c you might have to eat your words.
I am not here to answer your stupid questions
make a note of that
No your here to offer meritless commentary!!
Exactly! You don't want to debate anything or learn anything or make any valid points your just a Narco-agent having a good timer bashing smokers. Besides you never present any factual truth in your comments just crap that I would expect any Narc to say... As for the comment of slowly poisoning the body...Hope you don"t drink anything with caffeine, don't use toothpaste, don't drink tap water, don't take aspirin, don't live in a big city etc. You are the one who needs to leave in the Real world, humans poison themselves and the world every minute of the day and there are much worse poisons than pot...like being a Narc.
i like
i like your comment thank you
You must be the head Narc
based on your own criteria, you must be the head narc
as you babble cardboard shit as your response
Must be these poisons holding your development back
cannabis addiction?
Cannabis and addiction in the same sentence? hhmmm that doesn't make sense. Cannabis is not physically addicting, read up some time and study before making ignorant statements that to the "stupid bus" riding people would be construed as an oxy moron!
Drug laws are changing in our favor; it's changing everyday!
Ask Marc Emery
Ask The Prince of Pot how the war of drugs is going,
and especially ask him about the legal shift in your favor
maybe enclose a hacksaw blade

Read it..

Sure sounds like bias to me..... maybe not.
^^^ the above is my response
^^^
the above is my response to the original poser... this is not a study done by NORML.
Read first post- Super Stoners
it says reported by NORML- not prepared by or commissioned by or conducted by
you stupid stoners
can't read or understand English as your _first language
then get all worked up about nothing
make up a pile of fictional crap
always drag in your fantasy Gestapo fears
and froth like a frig in a toilet when somebody lifts your lid
no wonder nobody respects you
you are brain damaged morons
and don;t even know you are slowly poisoning yourselves
keep away from normal people till the fences are up, OK?
Read first post
Thats exactly what the"stoners" said...so why does the first post call into question the validity of the study. The point is that NORML just reported it so why would Columbia University have an interest in lying or manipulate the facts toward a pro-pot agenda.

If you say something disrespectful, inaccurate or uncalled for expect to be bashed by many.
I encourage you to watch the 50 quotes. All of your heros are stoners.
poison
Why are so concerned that i am poisoning myself. It's my business what i decide to put in my body. Man i could really go for a big mac right now.
Also, why are you concerned that no one respects us?
Oh wow. Let me guess. Jesus, you have returned!
Can you do me a favor? Tell my grandfather i need to know where he left the keys to the old chevy.
What a superstar you are Bobbie
so I propose a deal:
We don;t concern ourselves
with what you put into your body
and you don't concern yourself
with the DEA destroying the
global drug trade.
everybody happy now?
Let's make a deal
we don;t concern ourselves with what poisons you put into your body
and you don;t concern yourself with the take down of the global drug trade
slow learner
This looks like the work of a troll posting yesterday, who also got poison confused with Cannabinoids. Maybe spend some time looking into toxins and non-toxins, it might sort out some of your confusion from post to post, day by day...
sarcasm
If you are talking about me, I was using sarcasm.
Your broken watch analogy
Your broken watch analogy fails. For too long you people have put it out that you have the solution to the problem- there never was a problem, bigotry, racism and hate brought about these intolerably bad drug laws and propaganda seeded and grew the opinions. You people, look at what you have reaped- look at the violence and the criminality and consider yourselves to be the broken ones. We already do- but unlike you, we won't jail you, just offer you a joint and a chance at some peace.
2012- Time for the pagan revolution.

NORML and Paul Armentano are H.E.R.O.'s to our planet...
Thanks for all your hard work Paul,and all the brilliant folks at NORML-MPP-et.al.. David Borden's recent study report on Huff Post (posted on CC also),was largely ignored. The people with college education and liberal bent want to comment on Two-headed cow from Egypt--Lindsey Lohan and Mel Gibson.I'll take Paul Armentano.David Borden,Allen St.Pierre and those young guys at MPP.We have the science,solutions,and the loving hearts to reform our social order. Don't let the "appeal to emotion" from trolling BUSH-DEA waste your time.Educate the uninformed,both young and old. ONELOVE
the feds
the feds have staged several burglaries and robberies in California, now the local city councils and law enforcement that has been federalized and it's being funded by federal dollars are going after the dispensaries, while they release dangerous criminals.http://www.fresnobee.com/2010/07/12/2004239/fresno-co-targets-medical-pot.html

zoning
Thanks for the links. That zoning crap is irrational.
If they want to get serious about zoning they would have to do it to tobacco and liquor too. But, god forbid anyone should have to walk more than a block to get knee walking drunk.
Total b.s.
Totally agree with you MOFTA
I also think it's B.S. that they want to restrict sales of Cannabis to 1 Oz. at a time.....but anyone can go to a liquirstore and buy enough booze to kill themselves and at least five other people. WTF!!! Does not make sense....
P.S. and don't get me started on prescription/over the counter drugs vs. medical MJ.
