A bit of a puzzle

It would seem that doctors in Britain are getting more and more certain that high doses of THC (such as in strong strains of cannabis) can cause psychosis, even in people who have shown no previous disposition for that illness.

Yet, in a study that was not publicised much, a retrospective study of the rate of schizophrenia and psychosis in Britain did not indicate any increase in the period following substantial increase in the use of cannabis.

Worth more research, I am sure, before it can be fully understood what is going on. (Or before you could be very confident that legalisation would be a safe measure for public health.)
