For schizophrenia, it's maybe likely if your family has a history of the disease. One of my friend's uncles is a schizo, but she has smoked before (now she doesn't out of personal preference). It doesn't MAKE you into a schizo ^^

And if it’s a trait that’s been passed down through family, once again it’s really not the weed that makes you schizophrenic. I’m not schizophrenic by any means, but I believe it’s kind of like being paranoid while high. Since I don’t have it, I just have the typical high paranoid thoughts but having schizophrenia just intensifies the paranoia. Like I said, I could be totally wrong but that’s just my view on it haha.
