Thats silly. spend all that money to raid someone just for an alleged plant?
u make it sound so innocuous. but it causes schizophrenia in some people
That'd have to be a pretty major study to prove it. You'd have to collect at least a thousand people people in various age, geographical, and ethnic groups, then have one group smoking and one group not, with regular, frequent drug testing. At the start and end, you'd have to then give everyone a psych exam -- this'd help remove any problems with selection bias, I'd guess.
Given how many schizophrenics are undiagnosed, I'd be more willing to bet the possible temporary paranoia of smoking exacerbates the person's eccentricities enough to lead to hospitalization which then leads to a schizophrenia diagnosis. If they put you in the psych ward to start out with in a hospital, that being on your record might influence whether or not a borderline's diagnosed, too.
I think that weed use does lead to an increased level of paranoia. I don't think the level of paranoia would lead to a person being put in a psych ward if they otherwise do not have a mental illness. I would argue that a good portion of the paranoia from weed use is the consequences of getting caught with/using it.
I have however read studies that do link an increased risk of schizophrenia to use of weed
