420 with CNW — Genetics Study Explains Why Some Marijuana Users Become Addicted
A new genetic study is offering fresh insight into why some people can use cannabis without becoming dependent while others go on to develop cannabis use disorder. The research suggests that occasional cannabis use and problematic addiction are connected to separate biological pathways in the brain rather than representing different stages of the same process. The study, backed by the Yale Center for the Science of Cannabis and Cannabinoids (YC-SCAN2), combined genome-wide genetic data with advanced brain imaging to explore the biological differences between CUD and cannabis use. Scientists analyzed thousands of MRI-based brain measurements, known as imaging-derived phenotypes, which capture details about brain structure…
