I have to wonder, though, about cause and effect.
For example, on a possible relationship between marijuana use and the development of schizophrenia. The schizophrenia seems to develop after long-term pot use, so it is blamed on the pot use. The only problem is that it doesn't take into account the fact that for most people schizophrenia develops very slowly, and there is evidence that the first symptoms, termed self-disorders which represent an instability in the self-world structure leading to alarming and agonizing but also very subtle and insidious symptoms that are NOT experienced by the patients as symptoms of a disease, already develop by childhood or early adolescence (emphases added):

This basic self-world structure is disturbed in schizophrenia spectrum disorders, ie, it is constantly challenged, unstable, and oscillating, resulting in alarming and alienating anomalous self-experiences (also termed ?self-disorders?), typically occurring already in childhood or early adolescence. The patients feel ephemeral, lacking core identity, profoundly, yet often ineffably different from others (Anderssein) and alienated from the social world. There is a diminished sense of existing as a bodily subject, distortions of the first-person perspective with a failing sense of ?mineness? of the field of awareness (eg, ?it feels as if the thoughts aren?t really mine?), and a deficient sense of privacy of the inner world. There is a significant lack of attunement and immersion in the world, inadequate prereflective grasp of self-evident meanings (perplexity), and hyper-reflectivity (eg, ?I only live in my head? and ?I always observe myself?). Although patients often suffer from self-disorders, the latter are usually lived in an ego-syntonic way, as modes rather than as objects, of the patients? experience, ie, often affecting more the ?how? than the ?what? of experience. What is important to emphasize at this point is that the self-disorders, reflecting the unstable basic self-world structure, destabilize the natural ontological attitude and may throw the patient into a new ontological-existential perspective, an often solipsistic framework, no longer ruled by the ?natural? certitudes concerning space, time, causality, and noncontradiction. Unconstrained by these certitudes, the world may appear as only apparent or staged, ontologically mind-dependent, prone to noncausal relations, and the patient may experience a unique access to deeper layers of reality, which are inaccessible to others. Often, these experiences evoke a specific sense of grandiosity, leaving others to be seen as oblivious to the true nature of reality and only concerned with everyday trivialities.

The patients often do not experience their initial self-disorders, from which psychosis emerges, as ?symptoms? of an illness (similar to how an intense abdominal pain might be a symptom of appendicitis) but rather as intrinsic and habitual aspects of their existence and identity.

This seems pretty agonizing (and I admit I experienced a lot of this throughout my life though I never used pot). It may be that those using pot who go on to develop schizophrenia are already experiencing these very early symptoms of schizophrenia and are seeking relief from the agony of their self-disorders by using substances, which self-disorders will later on in development give way to full-blown schizophrenic psychosis.
