Hurray for Google understanding my misspelling cannabis.

"Now two additional research publications weigh in on this issue. Both were published in the February 2011 issue of Archives of General Psychiatry. Both studies come from the Genetic Risk and Outcome of Psychosis (GROUP) study sample.
The first manuscript summarized the results of study using a sibling-control and cross-sibling comparison. Eleven hundred twenty subjects with a psychotic disorder were compared to 1057 siblings and 590 controls. In summary the results of this study were:
- You were much more likely to report psychotic symptoms (both positive and negative psychotic symptoms) with cannabis use if you had a sibling with psychosis
- Siblings using cannabis resembled psychotic siblings in their ratings much more than siblings not using cannabis
- The statistical analysis of the relationship pointed to a familial risk increasing cannabis sensitivity, rather than familial risk increasing use of cannabis
...
These two studies add to support for a role for cannabis to be a potential risk factor for some forms of psychosis and schizophrenia. The genetic and molecular correlations in this study a mutually supportive. So the take home message seems to be the same--there just seems to be more support the message is research based.
Some individuals may have a genetic risk for psychotic symptoms related to cannabis use. This is not a trivial risk. If you have a sibling or other relative with psychosis, or if you experience psychotic symptoms with cannabis use, don't use cannabis."
I am one of these people. My anecdotal evidence + research > your anecdotal evidence.
