Tech sorry this is a sore spot for me but there is 0 connection between schizophrenia and cannabis. That "old wives tale" comes from one biased study done by the american DEA it was a double blind test (so technically no one even had the answer). Australian universities just finished a 50 year study on the subject (almost all australian universities were in on the project) and they found no correlation and used almost every scientific method and testing available and had more than 40,000 subjects tested unlike the DEA did who just used 200 people who already had schizophrenia. (which in fact rejected the first study which found no correlation and ordered them to "do it again").
