Cannabis Leaves Molecular Marks on DNA Linked to Psychosis
Summary: 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.
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.

As cannabis use becomes more prevalent, understanding its biological impact is critical, especially for mental health.
Published in Molecular Psychiatry, this is the first study to suggest that the use of high potency cannabis leaves a distinct mark on DNA, providing valuable insights into the biological impact of cannabis use.
