All that demonstrates is that they cannot link Cannabis to a specific form of the disease.

"Investigators in the study did not address whether cannabis consumers had greater odds of contracting schizophrenia when compared to otherwise matched controls who did not have a history of cannabis use. However, a 2006 review by Britain's Advisory Council on the Misuse of Drugs (ACMD) previously concluded, "For individuals, the current evidence suggests, at worst, that using cannabis increases lifetime risk of developing schizophrenia by one percent." 13"

Selective reading will not prove your point. The next paragraph goes on to suggest that until the linkage can bee disproven the substance should be controlled. From my point of view, it might as well remain illegal in that case.
