It is not a myth. It can cause a Schizophrenia-type illness in susceptible individuals, especially people in their late teens or early twenties who smoked heavily from their early to mid teens. Some of these go on to develop persistent, full blown Schizophrenia. The first signs are when paranoia starts to be a dominant feeling whenever the individual consumes cannabis - time to give it up.
Cannabis causing Psychosis is a well-constructed Myth.
Clinical trials illustrate opposite of what you state showing Cannabis as an effective treatment against Schizophrenia.
