Psychosis, schizophrenia and madness for Cannabis users

The time it takes for brain cells to be destroyed and symptoms of psychosis to appear varies from person to person. This duration of use varies from person to person. Some people are genetically predisposed to the condition and, with repeated use, develop psychosis and insanity for the rest of their lives. They must take medication for life, but ultimately the end of this path is nothing but illness and a waste of time.
