Some people think this means pot is inherently bad. Its not.

Its more like having a job and studying. It makes you more prone to be on the drop out side.
 
ITT: People who don't understand the difference between an experiment and a case study.
Yup.

And I never liked correlation =/= causation. The more accurate way of saying it is correlation !---> causation. Correlation can equal causation, but it does not imply causation.
 
What line of thinking? I've just been arguing that people shouldn't dismiss this study with a blanket "causation=/correlation."

And when you make baseless statements like accomplishments and achievements aren't scientific end-outcomes or clinically significant, then yes, it makes me think you don't know what you are talking about.

Not when the study doesn't (and can't) find out whether people accomplish less because they are less driven and motivated or the drugs caused it.

Accomplishment isn't the symptom of a disease. Human beings have free will and they make choices that change the outcome of their lifes.
 
Yeah, this seems to me like there is a missing factoid.
People who are unmotivated in school are probably suffering from depression already and using weed for self-medicating purposes, and if existing depression is a factor, it explains the suicide rates.
Does the study address if those who suffer from depression are more likely to smoke weed? If we knew that, it would be the missing part of this whole thing.

Try telling that to a depressed person, or any other person suffering from a psychiatric illness.

You just threw up decades of advancement in clinical psychology and psychiatric out of the window...

The depression and suicide ideation link is the weakest from the study and the authors admit this.

Also, this is a meta-study of three longitudinal studies, not a case study.

I'm still going through it, takes time to parse the information of a study.
 
Stuff that no study can reasonably control for, such as "made friends with the wrong crowd" and such.

I'm not advocating for marijuana or any kind of drug use, but conclusions like this always kind of bother me. The implication always seems to be that because they found a correlation in the statistics of a population look at over a period of time, that also means that those findings can be extrapolated to the larger population and it can safely be said that there is a risk of dropping out of school or killing yourself associated with smoking weed.
Theres a whole list of confounding factors they tried to take into account, this is detailed in the appendix. A large proportion of the participants in this study have been followed since birth up to age 28 to 35, and assessed throughout in regards to lots of things.

They included the factors and whether they preceeded cannabis use as a control in their statistical analysis to test the resilience of their results.
  • Cognition and behaviour: School problems; conduct disorder; attentional problems; GPA.
  • Substance use: Smoked cigarettes; drank alcohol; any other illicit drug use.
  • Mental health: Depression and anxiety.
  • Demographics: Sex; ethnicity; socio-economic status; family living standards.
  • Parental substance use: Mother/Father smoking and drinking status, parental illicit drug use
  • Parental mental health: Depression, anxiety, and suicidal behavior.
  • Parental demographics: Mother/Father level of education, Divorce/separations.
  • Peer level: Antisocial peer activites; Substance use by best friends; deviant peer affiliations (peer drug use, peer offending, antisocial behaviour)

If you were skipping class to get high, wouldn't that be the drug itself affecting you?

If that particular drug didn't exist, they would probably skip classes to do something else.

The problem with pinning marijuana as the cause for the increased odds of the problems listed in the article is that it implies that those odds would be severely reduced should marijuana be completely eliminated, which sounds like a big fallacy.
 
Smoked weed all through high school very heavily and ended up just fine. I'd even say I'm more successful than the average 22 year old. I know citing one off examples doesn't mean anything but...blaming pot for kids not finishing school seems way off to me.

The public school system hasn't kept up over time and does nothing to engage kids these days. I can't blame anyone for wanting to smoke a blunt over sitting in a classroom being talked at about something you have no interest in and will never use ever again.

Not trying to refute the study since I haven't read it but there are so many more factors than pot smoking that lead to people quitting school.
 
Everyone that's still spewing the "Correlation and causation. It's obviously wrong! Long live weed!" argument, please do yourself a favor and read this.

Thank you for the summary.
 
I want to see the studies about teens drinking alcohol everyday!

I wouldn't be surprised if the results were similar, if not worse.

No more needs to be said.

Through correlation, my professor was able to "prove" that people who wear black shirts are more likely to become meth addicts.

Actually, it's pretty intellectually dishonest and antiscience for a person to dismiss an entire study based on that argument. At least try to have a criticisms of the study design, instead of relying on a blanket statement. It's the same argument conservatives use when refuting gun-control and global warming studies.
 
Obama said the only problem with pot is that, like alcohol, has an addiction problem. Too much use. If you just smoked a joint or a hit.. that goes away very fast. It's pot, it isn't gasoline or cat litter. I think people are scared of it, but hell there's worse medications out there. Pot isn't like pain pills or anxiety medication either.

Teens don't smoke, focus on your education. Let the adults enjoy the munchies.

The problem is that teens have not yet developed the capacity to comprehend long-term consequences and are more susceptible to developing addictions and other bad habits.

And I know that there is a hysteria surrounding weed but it seems like there are few people in the middle.

It's either:
"WEED KILLS YOU AND YOUR FAMILY AND YOUR DOG"
or
"WEED: THE MAGIC PLANT BIG PHARMA DOESN'T WANT YOU TO KNOW ABOUT."

Marijuana isn't that strong of a drug but that doesn't mean it's completely free from potentially harmful side-effects (specifically if you're smoking it on a regular basis).

For every bad case there's a few dozen of successful pot smoking people. Take how states are legalizing it now. The guy bringing his pot home that he bought from the store versus the guy whose still in jail over selling it. Either way they'll hear about it if it gets legalized throughout the entire country. It should of been legal for adult use by now, everywhere. And that's coming from me someone who stopped using and quit as a minor.
 
I have trouble believing anything from the UK about weed after they ran their previous drug czar out for saying some unpopular things/.
 
You should smoke when you're in your 20s because your brain, lifestyle, and work ethic is still developing as a teenager. It's just too much of a liability where it's criminalized, and not worth the money, trouble, health, etc.
Very true. Not everyone reaches the same milestones at the same times, so the later the better in terms of it not being a "factor" in the negative sense.
 
Thise kind of drugs never do any good to anybody and sometimes it makes people to make bad choices, it should be ilegal in all countries.

Luckily where i live is ilegal but i was surprised of how many people used it in a daily basis when i lived in colorado.

This could be said about TONS of things, many of which are seen as perfectly normal and okay by most people.
 
I wonder...

How many teens smoke daily?
How many teens never complete highschool?
Of those teens, how many smoke daily?

How many teens never go to college?
Of those teens, how many smoke daily?

That would show us the scope of this, at least.

Now, is the habit a cause or a symptom?
What other commonalities to the smokers have with other drop outs?

edit: looks like the article answered my last question (I think)

They found "clear and consistent associations between frequency of cannabis use during adolescence and most young adult outcomes investigated, even after controlling for 53 potential confounding factors including age, sex, ethnicity, socioeconomic status, use of other drugs, and mental illness."
 
Eh, it shouldn't be a problem if my hypothetical children are raised correctly. I'll make sure they know weed is just a recreational drug and school should always be a priority.

While their body is still growing? Not on my watch. I don't think it's good for the brain's development to start consuming weed or alcohol before hitting 17.

And I say that as a stoner.
 
Since others apparently do not want post the article for various reasons, I have done so. The entire article is now on free to view on Scribd. The link is below:

There can no excuse now regarding the level of debate here. It will be interesting to see if posters will actually bother to read it in its entirety and formulate their critiques or praises appropriately, or if this thread will sink faster than a lead weight in the sea.

Some enterprising poster can even start a betting pool on those two possibilities.
 
I started smoking it midway through college, became psychologically dependent on it for about 2 years while my grades plummeted and my social life slowly became nearly non existent. I haven't been off but for a few months but already my social life is growing again and my grades are rising.

Some people can take it responsibly in moderation...I'm not one of those people. Before I was fairly adamant about it and I only smoked socially, but after losing a long term girlfriend and my best bud committing suicide within a 2 month window, next thing you know I was a full blown pothead. I was a mess for those two years and I really wish I could go back and smack some sense into myself, I'm only now coming to terms with what happened then.

Just to be clear, I'm not blaming the drug itself, it was a series of my own increasingly terrible decisions in the wake of severe depression that led me down that path. Choosing to self medicate depression with Marijuana was just the bad decision I made most.
 
Commonwealth nations are still suspect. UK gov has decided that pot killed Jesus. Wouldn't surprise me to see people bowing where the wind blows.

That's not what this study says. It's evaluating the effects of marijuana use in adolescents due to the changing laws and attitudes towards it. There is strong data to link heavy use with associated risks. It's not making judgement of legalization.

Posters are making wild extrapolations without reading the study.

I was under the assumption that posting full articles was against the TOS. I appreciate your effort though in trying to get more people to actually read the article.

I refuse to read such poppycock. Kids shouldn't smoke weed anyway. I'm just stating my general distrust of certain sources i.e. the UK and related nation states in reference to marijuana and it's effects. Never mind legalization.
