#13 Wendigo Psychosis
Wendigo psychosis is a condition with a psychotic origin where the person develops a craving for human flesh.
The existence of this disorder is still up for debate, but some eyewitnesses have come forward over the years.
The person goes on to act violently towards others. With an insatiable taste for human flesh, they turn to cannabilism despite the availability of other food items.
The presence of this disorder is traced back to Algonquin Indians. The community believed that the members of the tribe engaged in cannabilism were possessed by the flesh-eating spirit of Wendigo!
Old accounts of this disorder talk of native healers and western doctors. If neither could help the sufferer, an execution was done.
