A Study Reveals That High-Potency Cannabis Can Alter DNA

A recent study published in 2024 has revealed that consuming high-potency cannabis (defined as having THC content of 10% or more) can leave a unique mark on users' DNA. The research, conducted by King’s College London and University of Exeter, shows that THC affects DNA methylation, a process that regulates gene activity without altering the DNA sequence. These changes could influence genes related to energy production and the immune system, particularly in frequent users.

Mental Health Implications

The study also found that DNA modifications differ between individuals who have experienced psychotic episodes and those who have not. This discovery suggests the potential for future blood tests to identify cannabis users at a higher risk of developing psychotic disorders, enabling earlier interventions.

Clinical Perspective and Future Research

With increasing cannabis consumption worldwide due to legalization, the study highlights the need for a deeper understanding of the biological effects of regular cannabis use, especially of high-potency varieties. Future research should explore whether these DNA changes can be reversed or if they have long-term impacts.

In conclusion, high-potency cannabis not only affects the central nervous system immediately but also leaves a biological footprint that could have significant implications for mental health and the risk of psychosis.
