It's not a myth. I know you went through the University of Google searches to derive your opinion, however that does not reflect the current understanding of the drug. I don't know what your definition of "absolutely false" is, however it clearly doesn't come from the majority of studies done on THC's causative nature of mental illness.
LOL at the 'University of Google'
I just took the sources of the Wikipedia text instead of copying the text itself and just claiming that repeated consumption of cannabis causes cognitive impairment and severely affects things like attention, perception or memory, with the bonus of turning you into an schitzo. I thought they're good as entry level.
I guess, since you cannot ask for sauce to try and refute me like a redditor, now we're going and discrediting the sources provided. I shall imagine, from your comment, using Google Scholar would not be deemed appropriate by you.
If you take a look at those studies, you would have concluded, in between all the dumb science-speak, that cannabis
does alter how your brain works. That does mean that it doesn't matter if you are not predisposed to a psychotic breakdown, the drug does alter your brain in such a way that it will create that possibility.
Please, note that all these studies come with the "More research is needed" typical disclaimer.
Now I'm asking you some questions:
Are there studies that claim there are no links between tobacco and cancer, yes or no?
Is there any vested interest on Science (tm) denying a link between cancer and tobacco, yes or no?
Would such a vested interest in driving this outcome be able to disrupt research about it creating confusion, yes or no?
Would such a vested interest obsess over very direct relationships, attacking more complex studies on the relationship between tobacco and cancer, yes or no?
Does such a vested interest have the capacity to affect who gets funds or not in any way, yes or not?
And finally,
Is there a vested interest and concerted effort in normalizing consumption of cannabis, yes or no?
Is there a growing industry around cannabis yes or no?
Are
you a consumer of cannabis, yes or no?
I rest my case, your honour.
