I thought that I would share this article, which claims that cannabis has been shown to bring on mental-illness 3 years earlier than it would have done otherwise!
This area is admittedly complicated and I'm now wondering if we shall ever really be able to assess it's effects relating to psychosis and other illnesses, as there are many schools of thought that contradict.
But it's interesting none-the-less and shall hopefully tell us something.
