Tillbaka till studien som svenska staten & myndigheterna använder för att "bevisa" att cannabis är både farligt och skadligt. För det första, på samma sida finns länkat till 2 studier som motsäger att cannabis dödar hjärnceller. Här finns en studie från 2011 där man funnit att cannabis skyddar hjärnceller, till och med reparerar skadade hjärnceller. Dessutom, tidigare i bloggen refererar jag till ett antal stora rapporter som jag gav namnet *Science*. Ingen av dessa rapporter tar upp att cannabis skadar eller dödar hjärnceller. Här är en annan omfattande studie (Cannabis and the brain) som också motsäger att cannabis skadar eller dödar hjärnceller. Istället tar den upp att studien som "bevisar" att cannabis dödar hjärnceller har väldigt låg evidensstyrka. Varför? Väldigt få studier har kunnat reproducera resultatet, alltså att cannabis dödar hjärnceller! Cannabis and the brain nämner också ett antal studier där resultatet visar att cannabis har neuroskyddande egenskaper, alltså skyddar hjärnceller från skador.
Några referenser till på att cannabis har neuroskyddande egenskaper:
