Cannabis Smoking Makes Students Less Likely To Pass University Courses 291

Bruce66423 writes: A large scale European study shows that students who were unable to buy cannabis legally were 5% more likely to pass their University courses. Below-average students with no legal access to pot were 7.6% more likely to pass their courses, and the effect was five times more pronounced when dealing with courses involving math. One of the study's authors said, "We think this newfound effect on productivity from a change in legal access to cannabis is not negligible and should be, at least in the short run, politically relevant for any societal drug legalization and prohibition decision-making. In the bigger picture, our findings also indicate that soft drug consumption behavior is affected by their legal accessibility, which has not been causally demonstrated before. ... Considering the massive impact on cognitive performance high levels of THC have, I think it is reasonable to at least inform young users much more on consequences of consuming such products as compared with that of having a beer or pure vodka."

      Well, had you read the article ...

      “The effects we find are large, consistent and statistically very significant,” Marie told the Observer. “For example, we estimate that students who were no longer able to buy cannabis legally were 5% more likely to pass courses. The grade improvement this represents is about the same as having a qualified teacher and, more relevantly, similar to decreases in grades observed from reaching legal drinking age in the US.”

      So, about the same.

          No, not really. There are plenty of introverted people (i.e., not networkers) who learned valuable skills and got jobs based on knowledge gained in college. This is so blatantly obvious that I'm not even going to bother citing sources (a skill I learned in college). The burden of proof is on you. I will put this out for you though: do you really want a surgeon who skipped half of her classes operating on you? Do you really want your pediatrician diagnosing your childs illness based on google searches?
        • Then why do universities bother teaching courses in specific topics like mathematics, computer science, and whatnot? Surely there is still some intent to actually increase the student's domain knowledge in these areas?

          One can self-teach himself or take a MOOC here and there, but does that create a person with a well-rounded rich engineering base?

          • A typical bachelor's degree in engineering involves no more than 5 courses per term for 8 terms. Discard the wasted 1 course per term of humanities or other irrelevant drivel, that leaves 32 courses total, each of which consists of little more than learning the contents of one book. Look at a college catalog and degree requirements, figure out what those 32 books are, buy them and learn the contents.

              Oh, you miss the point of going to university entirely.

              You get the books, you learn the material, you skip the lectures, you get the qualification. The rest of the time is _for_ exposure to depraved fellow students.

          You, like many others mistakenly believe that the point of college is to get an education. In my estimation (as someone who has been involved with hiring for many different positions) A College degree (even from prestigious schools) is a poor indicator of intelligence, or ability. People who are capable, will learn from whatever source is available (And google is a much better source than all but a handful of professors). People who are not capable of learning on their own *must* go to a university to get an education, but these people make lousy employees, as they can never handle anything outside of the ordinary, and consequently are no better than ditch-diggers. Even the best schools in the world cant teach independent thinking. By the time a person gets to college, they either have it or they never will.

          You show me someone who graduated school while attending less than half their classes, and I'll show you someone who will be successful at whatever you give them to do. (This goes double for B.S. degrees).

          College is 100% about networking and creating relationships (both personal and professional). To that end, college social activities (including drinking) are an invaluable part of the experience. After all, its not about what you know, its about who you know.

          Social interaction is important as is the education aspect, but not even close to 100%, more like 25% (learning people skills), unless you are going to a really good college. One could argue that it's more important in Ivy league schools simply because the vast majority of people who get into Harvard, Yale, etc. are already smart enough and/or rich enough to get a job. The rest is just getting to know people who can help them with their ambitions. However, social interaction itself in other universities

      Due to my own empirical observations, I would have to disagree. In my late teens and early twenties when studying liberal arts, philosophy and making my living as an illustrator and animator, I rarely drank but would smoke weed pretty frequently and maintained a 3.6 to 4.0 GPA without even trying.

      However, when I decided to teach myself to code a few years later, I found the weed really got in the way, so bought some beer and found I could drink a fair amount of beer and still grok the info I needed and retain it. As such, I stopped smoking weed and started drinking for my recreational pleasure.

      • But how did the alcohol affect your liberal arts education? Your research indicated the different drugs affected different parts of the brain.

        That's because you were studying liberal arts. Switching my major from computer science to philosophy took me from a 2.4 GPA to a 3.9 GPA overnight while eliminating the need for me to study.

      • Were you smoking when you missed the point about the effect being particularly notable in courses requiring math? I doubt you took many advanced math or technical classes in your liberal arts degree pursuit. I always found liberal arts classes to be a lot easier than my engineering ones.

      They need to work out how many of the students chose that university BECAUSE it featured legal access to cannabis. There is little doubt that some of the students there are there exactly because they have a tendency to over-indulge.

    Ok, what am I missing? I mean, this seems obvious.

    Being stoned, just like being drunk, has kind of an obvious affect on your current cognitive abilities. For both drugs, you are looking a a time-frame of hours where you cannot study or work effectively. TFA even notes that the magnitude of the effect on grades is similar.

    If you drink alcohol or smoke pot on nights when you need to be studying, your grades are going to suffer. If you restrict yourself to times when you really don't have any obligations, then there won't be a problem. Young adults being, well, young adults, they may not always have the necessary self-awareness and self-discipline - hence, their grade may suffer while they are learning this life lesson.

    Make sure people are aware of the effects of the drugs. Encourage self-control and self-discipline. Prohibition is, and has always been, a non-solution.

        Ordinarily, I'd agree with you. That's what I always tell my American friends, too. But this study has been done in the Netherlands. The drinking age is 18 (used to be 16 like in Germany, IIRC) and Dutch teenagers, much like any European teenagers are much more independent and self-reliant than their American counterparts. Helicopter parenting, while it does exist, is not very prevalent in Western or Northern Europe.

    Sure being a pot head is going to have a detrimental effect on your grades.

    I wonder if chewing bubble gum would also impact a below average student's exam scores. Seems like minimize the distractions from sex, alcohol, and cannabis would tend to help most below average students.

    Also, if you can only smoke in these Dutch coffee shops, and spend all your time there instead of in your apartment or dorm, then less studying might explain away some of the exam scores.

    But despite the above concerned, I think most of us all assumed that there is some cognitive impact while someone is using cannabis. The debate has always been if this is temporary or is the impact long term. I tend to find a lot of holes in research that shows the negative impact to be long term. I have a hunch that there could be some neutral impact that is long term (changes but not detrimental), but that has been rather tough to measure.
