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.

    Yes, that’s exactly what the study says. That’s there’s nothing indicating this “relief” (= lessen symptoms) is given by cannabis. They’re not even talking about a cure, so not sure why you’re even bringing this up.

      Because no matter what this study concludes, far too many people know for absolutely certain that conclusion isn’t true, based on the simple fact that their personal experience contradicts it.
