well, see here's the ugly truth about experiments...
they can be demonstrated in such a way that it
appears to favor one way when it should be the opposite...
phillip morris in their studies, when they
knew tobacco caused cancer, they just used a really high confidence level in their statistics so it
looked like it was relatively harmless...
and their could be confounding factors. For instance marijuana users tend to be certain types of ppl, it's in your genes, some ppl naturally are risk takers and so on...
....and these types of ppl probably are also more likely to develop or have undiagnosed schitzophrenia.
Also it says it increases the risk, 50 to 200 percent so that's a pretty big range, ya know, not very accurate statistics...imo
I am very picky about what statistics I accept as 'the truth' and I leave the rest in my 'maybe pile'...
edit: "The prevalence of schizophrenia is believed to be about five in 1,000 people. But because of the drug’s wide popularity, the researchers estimate that about 800 new cases of psychosis could be prevented by reducing marijuana use."
It says 5/1000 ppl have schizo...and 800 new cases could have been prevented...
what does that mean...800 cases in the UK?...wtf, that is so ambiguous. Either way your risk of developing schizo is pretty low...
