"Teenage cannabis users are more likely to suffer psychotic symptoms that raise the risk of full-blown mental illness in later life, claim researchers.Adolescent drug takers interviewed for the largest study of its kind reported experiencing at least three symptoms indicating a risk of psychosis.

Frequent drug users were more at risk but even youngsters dabbling at an early stage were vulnerable."
