A study has revealed that frequent use of high-potency cannabis leaves unique molecular marks on DNA, particularly affecting genes related to energy and immune function. Researchers found that DNA methylation—an epigenetic modification—differed between frequent cannabis users who had experienced psychosis and those who had not, suggesting a possible genetic link to psychosis risk. This discovery may enable DNA blood tests to help identify cannabis users more susceptible to psychosis, potentially informing future preventative approaches. As cannabis use becomes more prevalent, understanding its biological impact is critical, especially for mental health.
Key Facts:
- High-potency cannabis affects genes linked to energy and immune response.
- Frequent use leaves distinct DNA marks, potentially linked to psychosis risk.
- Findings could enable future DNA tests for psychosis susceptibility in cannabis users.
