fast food doesn't affect the mind like pot does
Yes, fast food is much more addictive.

ok, so are cigarettes. But potheads tend to be stupider than fat people. In general, o fcourse

Here is a better article.

Another article, with differing data on the research

All three articles quote different data for the number of participants as well as other factors in the study.

Quoted from the first article:
"The study doesn't definitively link marijuana use to the cognitive problems, and it's possible that other factors could be to blame. Prior research has also offered conflicting findings about the mental effects of marijuana. "

Gee 20 people, that is a HUGE pool of data, how did they keep track of it all? :roll:

Might as well put a study together of 20 homosexual couples and track their sexual tendencies, then link homosexual behavior with AIDS and call it a credible "study".

imho, i would throw out this study, doesn't prove anything until they prove one way or another what i have said above.


muwhahah..mabe.

Not really sure why this would be surprising.

I'm sure if you did any drug for 10 years, your body would suffer.

Actually that would be an interesting study, though the results would be as meaningless as this one.

Riddle me this, though. Assuming the study is accurate, why is being "stupider" a bad thing? Sure I "know" intelligence is valuable, and I'm as snobby and isolated as JLGatsby when it comes to absolutely loathing the world's population that exists outside the boundaries of my dermis ...

but since so many people are stupid anyway, what's the harm in people dumbing themselves down?

What would be interesting to me is seeing quantitative and qualitative personality measures compared against each other.

dunno, I don't need a study to know that people who do pot often get a lot stupider than they used be before they started smoking. It's quite sad, really.

I don't think they are obvious at all. There is such a long history of misinformation about pot that many people seem to have a hard time forming an opinion free from any reefer madness refrences.

Just look at the different attitude the general public has towards alcohol. I'd bet a similar study of 64 alcoholics would result in just as bad if not worse cognitive skills, but I never hear people say beer fries your brain.

Does it not seem odd to you that despite common sense making this overwhelmingly apparent to you, that in 2006, it is still hotly contested, and the latest entry is a study in Greece of limited number and questionable subjects?

If you have ever been around a person who smokes pot then you KNOW that pot makes you slower and dumber(relative). Ofcourse there are always flukes where one out of many many may be a smart pot head.

Are brains from Greece any different from brains around the world? Secondly, since it is a study done in a University Hospital, I'm hoping/partially assuming that the sample was chosen randomly, and thirdly, the sample size appears to be large enough provided the sample is somewhat normally distributed. Even so, the article states that it controls many other variables (although I'd like to know what) and thereby discovered that there were significant differences.

Anyways, it's definitely not hotly contested that marijuana affects your mind, and nearly everyone I know agrees that regular marijuana use over long periods of time would probably dumb you down... there's a reason why the potheads tend to be stupider.

And my assertion wasn't just based on common sense, it was based on my own personal experiences with other people

Interesting. Though the truly intelligent people in our society are not "snobby and isolated". Nor do they loathe the world's population.

Truly intellgent people appreciate the entire world around them for what it is and don't act superior to the rest of the world. The people who do that are actually the very sad, misguided and weak people. Shutting out the rest of the world is really just accepting the fact that the rest of the world is better than you, and not the other way around.

Don't be one of thoes people, there is no merit to it. You are merely fooling yourself into thinking you're something more than you really are, and that's one hell of a waste of a life.

That's a pretty obvious conclusion. I'd bet they would find the exact same thing with alcohol.

The people who use it moderately are fine, however. Hell, some of the smartest friends I know smoke weed, it doesn't seem to have affected them at all.

I'd be much more inclined towards a drug/psychological study from a Scandinavian country to be honest. Then again, I wouldn't go to Brazil for surgery, and there are plenty who are fine with that.

The thing I'm trying to get at - and I'm not trying to speak as an expert, but as someone trying to work my way through my own question/answer .. is that tests of intelligence and dexterity don't show any effect.

Look at the study again and look at the potheads you know.

I'm sure you know plenty of "dumb potheads" who have smoked less than 4 joints a week or for less than 10 years.

But even in people who smoked UP TO that quantity and frequency, the study did not find a significant decrease in intelligence or dexterity.

I'm not denying that marijuana can make people "blunted" :p , but I think that what sober observers are taking as being "a dumb pothead" falls outside of the psychological scale that measures intelligence.

I am thinking of two possibilities.

1. We are all stupid in a "pothead" fashion. However, as soon as we know someone smokes, we ascribe this flaw of humanity as being "because they smoke pot".

2. Pot makes you into a "stupid pothead", but your stupididty, despite being apparent to all, is not measurable on a clinical scale. That's pretty deep, dude.

Did you miss my post about where they got their sample from? I'd also like to know how they controlled for other variables, particularly other drug use and level of education.

Your assertion that potheads tend to be stupid is not exactly based on solid ground. You probably formed this opinion from two things; one being that some adult probably warned you that pots bad, it will fry your brain etc when you were a kid. Two, that warning was reinforced throughout your life when you ran into what I call "Spicolli stoners", those who are content to dropout of life and get stoned all day all while advertising it to the whole world like the guy from Fast Times at Ridgemont High movie.

However your likely missing the other side of the coin, all the people who smoke pot responsibly in privacy and don't go around looking like a hippy with a pot leaf tshirt, the kind of people who are smart enough to never admit it for fear of repurcusion or prejudice from all the small minded people who would just love to judge them.

Yes I'm serious.

correlation != causation... could it be possible that those who smoke pot are just dumber overall than those that do, therefore they do worse on tests.

Excellent post.

It's the same way with alcohol. For every person that is content being drunk 24/7, dropping out of life.. there are 10 that drink responsibly.

But on the other hand the burn outs that just smoke all the time who get offered 50 bucks to come participate in a study about marijuana are gonna jump at it. Then you have the short-term (5-10) year smokers who are probably mostly college students who would do anything for 50 bucks.


"Messinis and colleagues recruited 64 people from a drug-abuse treatment program in Athens".

This is like recruiting people from AA to study the effects of alcohol. It may give some good insights into people who have an alcohol addiction, but it won't tell us much about all the millions of alcohol users who manage to drink most of their lives without becoming an alcoholic.

where did you get the full article from?

Even if the study was unbiased, contained a representative sample of the population, and produced results impartial to any political agenda, it still means nothing with regard to whether or not the drug should be legalized. I would imagine that people who drink huge amounts of alcohol of a period of years would be prone to some physical and psychological effects, just the same as those who heavily smoke tobacco do. Or heavily use any kind of drug.
