Heavy marijuana use increases schizophrenia in men, study finds
Original journal article (apparently not linked to in the Bloomberg piece):<p><i>Association between cannabis use disorder and schizophrenia stronger in young males than in females</i> (May 4 2023)<p><a href="https:&#x2F;&#x2F;www.cambridge.org&#x2F;core&#x2F;journals&#x2F;psychological-medicine&#x2F;article&#x2F;association-between-cannabis-use-disorder-and-schizophrenia-stronger-in-young-males-than-in-females&#x2F;E1F8F0E09C6541CB8529A326C3641A68" rel="nofollow">https:&#x2F;&#x2F;www.cambridge.org&#x2F;core&#x2F;journals&#x2F;psychological-medici...</a><p>Interestingly, the journal article doesn&#x27;t bother to mention how cannabis use disorder (CUD) is defined; however, Bloomberg&#x27;s description &quot;frequent use despite negative consequences&quot; is essentially that of the DSM, and so is presumably what they&#x27;re using.<p>That is - not based any particular <i>rate</i> of consumption (which is of course difficult to measure reliably, especially in prohibitionist countries like Denmark).  But &quot;continued use despite negative consequences&quot;.<p>And that seems to be the crux of the matter:  what the article is saying, basically, is that &quot;people who continue to use despite negative consequences ... continue to suffer negative consequences.&quot;  Which is rather different from:  &quot;Heavy use, by itself, brings these consequences.&quot;
