Potter has seen the extreme effects of both substance abuse and schizophrenia in his role as a magistrate for his local court. He recounts a recent case where a seemingly pleasant teenager, suffering from acute and sudden psychotic illness, had turned to alcohol and become violent.  “He ended up smashing someone’s teeth out for not really any reason at all,” says Potter.

“…their daily routine unfolded much the way Leriadis had described it: Wake naturally, work in the garden, have a late lunch, take a nap. At sunset, they either visited neighbors or neighbors visited them. Their diet was also typical: a breakfast of goat’s milk, wine, sage tea or coffee, honey and bread. Lunch was almost always beans (lentils, garbanzos), potatoes, greens (fennel, dandelion or a spinachlike green called horta) and whatever seasonal vegetables their garden produced; dinner was bread and goat’s milk. At Christmas and Easter, they would slaughter the family pig and enjoy small portions of larded pork for the next several months… “

In places where an increase in the incidence of schizophrenia has been reported, these can be attributed mainly to substance abuse (eg Drug Induced Psychosis).
