There’s a large body of research that has shown people who use marijuana also have an increased risk of developing schizophrenia, but scientists have struggled to find conclusive evidence that this correlation necessarily means causation. A new study, published in the journal Nature Neuroscience and involving genetic data from the DNA ancestry database 23andMe, has confirmed that there is a “significant genetic correlation” that indicates the emergence of schizophrenia may lead to a greater probability of cannabis use.
So are people using marijuana to calm the symptoms of schizophrenia, or is marijuana use jump-starting the brain-chemical imbalance that contributes to it? Turns out it might be a lot more complicated than that.
Over the last several years, researchers at the International Cannabis Consortium project have been studying whether certain genetic variations indicate a predisposition towards
