    This is fear mongering disguised as “science”

    A population-based retrospective cohort study of 9.8 million people in Ontario, Canada, found that people with an emergency department visit for cannabis use or cannabis-induced psychosis were at a 14.3-fold and 241.6-fold higher risk of developing a schizophrenia-spectrum disorder within 3 years than the general population, respectively.4

    So another way to state this: people who are prone to mental health disorder are likely to LEARN ABOUT IT with cannabis, but it’s not causing healthy people to go crazy

    Some prohibitionist jumped on this to spin it as propaganda

      It sure sounds like they’re just saying that cannabis helped people detect schizophrenia earlier than they normally would have. Which would strike me as a good thing…

        Yall are sayin stuff like “learn about” and “detect” as if they got to just add that to their notes and continue on their day.

        Going from “might develop schizophrenia some day” to “inpatient for an episode right now” is a big difference.

        Schizophrenia is a mental health disorder that can be triggered by psychoactive substances, trauma, or other significant events/life changes. Not everyone who has schizophrenia was guaranteed to get it, it’s just that some people have the potential for it. A psychotic episode (whether substance-induced or organic) is a common trigger to cause schizophrenia in someone that had the potential to develop the disorder.

        If you have a family history of mental illnesses (particularly Schizophrenia and Bipolar disorder), significant THC use and substance-induced psychotic episodes can be the grain that tips the scale towards developing the disorder that may have otherwise been avoided.

        (TL;DR: if Schizophrenia runs in your family, be exceedingly careful about what psychoactive substances you use.)

      Some of us are more prone to mental health issues. Cannabis is a strong trigger. It is possible to go through life without triggers.

      I’m all for full legalisation but legal age for most substances should be simply higher because it’s way too risky and damaging before your brain fully develops, as evidenced by the this paper.

        There is no age where the brain stops developing. The idea that the brain stops developing at age 25 is a myth. This myth comes brain studies that studied brain development…up to an age of 25. Pediatric studies of brain development don’t extend into far adulthood.

        So to be clear: because some unknown small sliver of the population may have an issue with it, you want to bubble wrap all of society?

        That sounds pretty conservative to me. Too much, even

    I was using pretty hard after my mom died. Numbing myself every night for two years, it really messed myself up and my partners life. After taking a break for 4 months I saw and felt what it was doing to me and decided to reduce and use a different form for more control if needed. I take a gummy on fridays and Saturdays now, finally found the best option for me and sticking to it for almost 7 months. Be safe everyone.

      Too much of any mind-altering substance will cause mental debilitation at some point. Moderation in all things. I say this as someone who has gone hard on a few different drugs (including alcohol) throughout my life.

    I get that this is dear mongering propaganda but also, I kinda hate that you can’t buy any old school pot anymore.

    28% THC with no CBD just isn’t very enjoyable to me tbh.

    I miss that stuff that was like 18% THC and at least 0.5% CBD.

      1.) It’s stupid easy to grow your own for next to nothing, in “stealth” containersb ranging from 5gal buckets to full-on multi-plant gargants. (See: “space buckets”)

      2.) It’s called weed for a reason. Set a reminder on your phone to water, prune, tend to your buddy. Spend as little or as much as you feel like, depending on how into the new, meditative hobby you’ve embarked on.

      3.) Realize you’ve been spending far too much on something you can set & (mostly) forget.

      4.) Enjoy!

      You can also just buy straight up CBD and mix until your hearts content.

      You don’t have to fill it to the brim with high grade pot if you don’t want to.

    The “but alcohol is worse and its legal” crowd really rustles my jimmies in a bad way. I propose any reader to go trough every comment and post the best arguments for this being “fearmongering propaganda” under this reply.

      Man it almost like there is a know correlation between alcohol and violence or something.

        Yeah there is sociatal harm and personal harm. Both alcohol and THC can be damaging in their own ways. Your point?

      Never really done any investigation tyen have ypu. You should hear about this thing called sugar.

        Sugar? What? I was talking about high dosages. Ever been so high you thought your heart was going to explode? That shit was terrifying.

      You’re right, don’t mind the other commenters.

      With edibles or just strong weed, you can have heart palpitations that make you think you are dying. You aren’t actually going to, but it can feel that way when you are mega stoned.

      I mean, outliers always exist. Don’t think those are the norm.

        By definition of what a norm is, no, an outlier wouldn’t be the norm. But who’s to say Willie’s physical reaction to cannabis is an outlier?
