The latest study to poke holes in the blown-up fear of marijuana causing psychosis comes from the Institute of Psychiatry at King’s College London.
The study shows that a gene related to schizophrenia may lead people to want to smoke marijuana. Note that this is exactly the kind of flip of a “common understanding” that comes out of correlation studies:
Did the marijuana use cause the trouble?
Did something else cause the trouble and marijuana use just happened to be there?
Did something cause both?
This research seems to show that something caused both.
“We know that cannabis increases the risk of schizophrenia. Our study certainly does not rule this out, but it suggests that there is likely to be an association in the other direction as well – that a pre-disposition to schizophrenia also increases your likelihood of cannabis use,” Robert Power, who led the study, told Reuters.

With two states in the U.S legalizing marijuana use next to alcohol for adults, its use is becoming increasingly commonplace. A few previous studies have suggested that there may be a direct correlation between marijuana use in teenagers and the increased risk of a schizophrenia diagnosis in the future. A new study by researchers from Harvard Medical School and the VA Boston Healthcare system that compared families with a history of schizophrenia and those without found no evidence that marijuana use caused schizophrenia.
Researchers recruited 282 subjects from the New York and Boston metropolitan areas and divided them into four groups for the current study. They concluded that an increased familial morbid risk for schizophrenia is a crucial factor and the underlying basis for schizophrenia in these samples. Cannabis use by itself had nothing to do with the development of schizophrenia in teens who smoke marijuana. This is good news for people who smoked too much marijuana (cannabis), especially as teenagers and were worried that it might lead to schizophrenia and other dramatic problems in the future.

NIDA Position
Population studies reveal an association between cannabis use and increased risk of schizophrenia and, to a lesser extent, depression, and anxiety. There are now sufficient data indicating that marijuana may trigger the onset or relapse of schizophrenia in people predisposed to it, perhaps also intensifying their symptoms.
