New research has found a possible link between marijuana and schizophrenia.
Scientists took nearly 100 teens, both healthy and schizophrenic, and divided them into four groups. Researchers then performed MRI scans on their brains.
The healthy and schizophrenic teens with a history of smoking marijuana showed shrinkage in the regions of the brain connected with working memory.
That same group also scored lower in memory tests when compared to the healthy and schizophrenic patients who had never used the drug.
While the study does not establish that smoking pot can cause schizophrenia, it does suggest that marijuana use should be further examined for the brain changes it can cause.
