Sweden) over the past 20 years.

Those who were heavy consumers of cannabis at age 18 were over 600% more likely to be diagnosed with schizophrenia
over the next 15 years than
those did not take it. (see diagram below). Experts estimate that between 8% and 13% of all schizophrenia cases are
linked to marijuna / cannabis use
during teen years.

Researchers in New Zealand found that those who used cannabis by the age of 15 were more than three times (300%)
more likely to develop illnesses such as schizophrenia. Other research has backed this up, showing that cannabis use
increases the risk of psychosis by up to 700 percent for heavy users, and that the risk increases in proportion to the
amount of cannabis used (smoked or consumed). Additionally, the younger a person smokes/uses cannabis, the higher the
risk for schizophrenia, and the worse the schizophrenia is when the person does develop it.
Research by psychiatrists in inner-city areas speak of cannabis being a factor in up to 80 percent of schizophrenia
cases.
