Study clears cannabis of schizophrenia rap
No greater risk than general non-tokers
So at this point we can say that, no, that bad trip on some heavy shit does not lead on to schizophrenia. There’s no difference in incidence.
But the paper’s authors go much further:
Altogether, these findings, in addition to those of previous studies, indicate that cannabis-induced psychosis may not be a valid diagnosis but an early marker of schizophrenia.
That is, that the very idea of that bad trip is itself wrong. The disease is already there, simply wrongly diagnosed as being cannabis induced. And finally we get:
Rather, the degree of hereditary predisposition in individuals who receive treatment of cannabis-induced psychosis closely mirrors that in those who develop schizophrenia with no history of cannabis induced psychosis. The results agree with those of other studies that show that cannabis predominantly causes psychotic symptoms in those persons who are predisposed to develop psychosis or show signs of psychosis in the absence of cannabis use.
This goes a great deal further than my or anyone else’s original supposition, that pot consumption might cause problems only for those who are already predisposed to mental health problems. If it were simply this then we could deal with legalised pot simply by placing warnings upon it, as we do with nuts and nut allergies (umm, 'nut' possibly isn’t le mot juste there). But this finding goes further. There seems to be no evidence that cannabis consumption increases the incidence of these mental diseases at all. Incidence is the same for those who have had the "cannabis induced" version as it is in the general population, adjusting for the risks we perceive from the incidence of such problems in their immediate families. That there’s actually nothing to do with cannabis at all, that it just so happens that some who are becoming schizophrenic, something which is often marked by short episodes before it fully takes grip, happen to have been puffing 'erb when such episodes hit.
Thus there really is no logical leg for the government to stand upon in its reclassification of cannabis: there's not in fact one reason against the legalisation of the damn stuff and the increase in liberty and freedom that would result.
So, anyone think this is going to make any difference? No, thought not myself. OK, back to basics then, could the Murdochists and the Mailites let us know who is really to blame for the idiocy which is current drugs policy? ®
