Excess pot smokers might not be dangerous to society, but most I know I wouldn't exactly call motivated.
they're motivated in a way you may not be accustomed to.

Correlation and causation.
This article was published by the Lancet, one of the most prestigious medical journals. People in this thread are way to quick to dismiss it because "causation=/=correlation". If you read the article you see that the study accounted for 53 confounding factors and still found a strong association. An RCT would be the gold standard here obviously, but that would never be approved by an ethics committee.
Yea I don't really understand these studies. It isn't drug that's an issue it's the people that use it.
If you take away weed from a lazy person, he's most likely still going to be a lazy person.
Appeal to authority. Just because Lancet published it doesn't mean it's true. We all have brains and we can read and draw conclusions from what we've read.
Lancet has published highly criticized articles before, including "mass privatization in Russia was correlated with higher mortality rates", which is about as bogus as this one.
More importantly, it is not a MEDICAL study. The study conducted zero scientific experiment on the effects of weed on the human body.
That's very wrong, sorry.More importantly, it is not a MEDICAL study. The study conducted zero scientific experiment on the effects of weed on the human body.
Did you actually read the article? What are your specific criticisms?
Much better than establishing policy by gut feeling or personal anecdotes.
Correlation and causation.
QFT.
But seriously, why isn't statistics mandatory education in the US? Then maybe we'd have more people that thought critically.
The antiscience in this thread so far is on par with conservative's dismissal of global warming studies.
But isn't this how they test out any drug? For example, when they released those studies years back that said SSRI users committed suicide more often. It was frequent enough that I think it's listed as a symptom now.
The only thing we can hope for is that the study is as impartial as possible and considers other factors.
And I think most of us have anecdotal evidence where we know somebody who is addicted to it and never amounted to anything. There are some who can be constantly high and seem to function somewhat normally, but they are few.
The key is moderation. Every drug is bad for you if you consume too much.

With that said, marijuana still makes people lazy. People don't need statistics to know that. My friend smokes like an 1/8th a day, don't do shit.
Did you actually read the article? What are your specific criticisms? What would you have done to change the study?
Bullshit.
If anything, it's people implying that a study should not be doubted because it was published in a prestigious journal that are antiscience.
The whole "who are you to criticize?" angle is just a bunch of shit.
Although I think that weed is a symptom here and not a cause, teenagers shouldn't be smoking anything daily. It just ain't worth it.
Bullshit.

It is a study about lifestyle choices, not the actual effects of weed has on the human body. Is it that hard to understand? All it says is that people who choose to do A are more likely to be B. It doesn't tell you what A does to your body.
They didn't seem to factor in personality and motivation, as well as prior knowledge of effects of drugs (aka drug culture).
Not sure about y'all, but anecdotally speaking it seems to be pretty well known pot is "supposed" to "chill you out."
Newsflash: People that want to do well in school don't take pot to study, they take Ritalin.
I think you quoted the wrong person because you didn't answer my questions.
Again, what did you find wrong with the study? I'm open to have the conversation if have legit complaints other than a blanket "causation=/correlation" statement that conservatives use to dismiss global warming.

I answered your questions. The whole study means nothing. People make choices, and so?
Bullshit.
Or is it that lazy people gravitate to enjoying marijuana frequently? Anecdotal evidence should not be used to make a definitive statement. I guarantee that there are people who are highly motivated and not lazy who also smoke marijuana.
I dunno man. Here they're basically doing exactly that: they're comparing usage statistics with dropout statistics with no other frame of reference. It does seem that type of study.
Did one of the factors include the person's ability to understand "delayed gratification"?
Even when accounting for confounders, the researcher still found a strong, dose-dependent relationship. I'm not sure how you say that means nothing.

The negative effects of weeds can only be found in a lab, not on a spreadsheet.
Because if I was a student and I spent 8 hours a week high instead of not high, it has a negative effect on my study. Doesn't take a study to figure that out.
You keep bringing up global warming. Global warming studies actually studied the actually effects of human pollution on climate. I suggest they do the same here.

Ha ha. Wow. So the risk of developing lung cancer from smoking cigarettes is a meaningless statistic...

yup.Daily...
After covariate adjustment, compared with individuals who had never used cannabis, those who were daily users before age 17 years had clear reductions in the odds of high-school completion (adjusted odds ratio 0·37, 95% CI 0·20—0·66) and degree attainment (0·38, 0·22—0·66), and substantially increased odds of later cannabis dependence (17·95, 9·44—34·12), use of other illicit drugs (7·80, 4·46—13·63), and suicide attempt (6·83, 2·04—22·90).
I can't find a list of all the factors, but even so, it still doesn't imply causation.
The only way to get actual proof of causation is to do something unethical (to conduct an actual study with actual humans).
Also, this is a pretty well-known experiment that explores personality.
Did one of the factors include the person's ability to understand "delayed gratification"?

The reason why smoking cigarettes cause lung cancer was found in a lab, with actual science behind it.
Try again.
The study itself looks fine at first glance. That's not what I'm criticizing. It's the conclusions that are being made that are problematic.
So the epidemiology studies mean nothing, right? Never heard of risk factors?The reason why smoking cigarettes cause lung cancer was found in a lab, with actual science behind it.
Try again.
This was done by various health departments, dude.

We recorded clear and consistent associations and dose-response relations between the frequency of adolescent cannabis use and all adverse young adult outcomes. After covariate adjustment, compared with individuals who had never used cannabis, those who were daily users before age 17 years had clear reductions in the odds of high-school completion (adjusted odds ratio 0·37, 95% CI 0·200·66) and degree attainment (0·38, 0·220·66), and substantially increased odds of later cannabis dependence (17·95, 9·4434·12), use of other illicit drugs (7·80, 4·4613·63), and suicide attempt (6·83, 2·0422·90).
Adverse sequelae of adolescent cannabis use are wide ranging and extend into young adulthood. Prevention or delay of cannabis use in adolescence is likely to have broad health and social benefits. Efforts to reform cannabis legislation should be carefully assessed to ensure they reduce adolescent cannabis use and prevent potentially adverse developmental effects.
Thank goodness I picked it up after high school while in college, thank you baby Jesus.
Methods
We integrated participant-level data from three large, long-running longitudinal studies from Australia and New Zealand: the Australian Temperament Project, the Christchurch Health and Development Study, and the Victorian Adolescent Health Cohort Study. We investigated the association between the maximum frequency of cannabis use before age 17 years (never, less than monthly, monthly or more, weekly or more, or daily) and seven developmental outcomes assessed up to age 30 years (high-school completion, attainment of university degree, cannabis dependence, use of other illicit drugs, suicide attempt, depression, and welfare dependence). The number of participants varied by outcome (N=2537 to N=3765).
That's not how it works, you need to think about the counter-conclusion.But isn't this how they test out any drug? For example, when they released those studies years back that said SSRI users committed suicide more often. It was frequent enough that I think it's listed as a symptom now..
These are the results directly from the abstract of the article:
They conclude that:
What is your criticism with that?
I read that, dude.
They used the method described in the OP which we have already debated so what's your point?
Sorry, Sir Ronald Fisher, but you lost that debate decades ago. And why would the experiment have to account for that? yes, there's always a chance of an unexpected confounding factor, but those chances are increasingly smaller the more controlled your experiment is.
Obvious study.
Long term drug use whether its marijuana, nicotine, alcohol, etc. is going to have its side effects.
Any sort of mind-altering drug is going to have a negative effect on the brain- especially one that is still undergoing development.
That you are wrong that they didn't take into account the way drugs affect the human brain. I'm not saying this is a spotless study, but I don't see you citing hard evince. I don't have access to the study, so I am not going to make blanket statements about their methods.
I don't like the results from this study so I will believe the other studies.
Good thing science gives you research that says everything is good and everything is bad so you can just believe whatever you want.
