I am in Toronto Canada. I am on the tail of this phenomenon, and I may even be able to do experiments to prove a theory I am working on.

As for the pharmaceudical companies, they will not research, develope, or market drugs unless there is a high demand.
Since our ailment is "pychosomatic" we are left hanging until the condition reaches statis amoung these entities. Shroom
P.S. There is the possibitily of a mass cover-up perpetrated by the big drug developers.
