The largest review of medicinal cannabis to date found it doesn’t effectively treat anxiety, depression, or PTSD—despite millions using it for those reasons. Researchers warn it could even make mental health worse, raising risks like psychosis and addiction while delaying proven treatments. Some limited benefits were seen for conditions like insomnia and autism, but the evidence is weak. The findings are fueling calls for stricter oversight as cannabis use continues to rise.

      Right, this does depend on the criteria for successful treatment.

      No one questions that pain killers are an effective treatment for pain, though they do nothing to cure the cause of the pain.

      “Huge study reveals ibuprofen doesn’t eliminate pain, just the sensation of it”

      Oh okay, I guess I should stop using it then?

      “Well, maybe… We need to do another Huge Study to confirm”

    i don’t recall that weed was ever used for those things, other then just as a copeing mechanism, i think the argument is that it was better then the other narcotics by a country mile.

    unless you are talking about charletons, but like we got people saying magic rocks cure cancer so like why would we need to validate their nonsense?

    Well, speaking for myself, it most certainly helps with my anxiety and depression. So they can stuff it for all I care.

    To be fair, the population of this meta analysis is severely underpowered to assess whether there is an effect for rare/semi-rare conditions. (population is couple of hundred in most areas) and it shows in the confidence intervals. Wouldn’t exactly call this a “huge” study.

    A better title would be “Study unable to determine if cannabis helps or hurts anxiety, depression, or PTSD because of lack of data” which sounds less glamorous.

    My experience was that weed made me accept not dealing with anything. It often made stuff worse but also allowed me to just accept that. It wasn’t fun and any claims of self medication was just an excuse not to stop.

    After I did stop for a few years and actually dealt with my shit, I can now use weed guilt free. Now it’s actually nice when I use it because I’m not using it to lie to myself.

    Most my stoner friends back then we’re like my pre healthier self too. That’s the problem with weed imo

    And might I ask who is funding this study and how are they being paid for by big pharma?

    I mean this is obviously anecdotal, but it helped me tremendously through some of the worst trauma I have ever encountered. I don’t really give a shit what any study says.

    Here we go with them trying to keep the lies going & sadly a lot will fall for this again but that’s why they legalized it so they could lace it for more future problems
