Researchers analyzed the gene profiles of more than 14,000 people and identified several genetic variants that significantly boost the risk of marijuana dependence. According to the researchers, it's the first study to pinpoint those variants.
"We were surprised to find a genetic risk overlap between cannabis dependence and major depression," said study senior author Dr. Joel Gelernter, a professor of psychiatry, genetics and of neuroscience at Yale University, in New Haven, Conn.
The findings might also help explain why many people with schizophrenia have marijuana dependence, he said in a university news release.
The study was published March 30 in the journal JAMA Psychiatry.
