Cannabis use linked to epigenetic changes, study finds

sciencealert.com

A new study involving over 1,000 adults suggests that cannabis use may lead to changes in the body's epigenome, which regulates gene activity. Researchers found multiple epigenetic markers linked to both recent and cumulative cannabis use over a 20-year period. The study identified 132 markers associated with recent cannabis use and 16 linked to cumulative use in blood samples taken after 20 years. Some markers were also associated with tobacco use, indicating potential similarities in how both substances affect gene regulation. While the research highlights associations between cannabis use and epigenetic changes, it does not establish a direct cause-and-effect relationship. Further studies are needed to explore these findings across different populations and their implications for health.
