Study Reveals Epigenetic Impact of Cannabis Use

A study involving over 1,000 adults suggests that cannabis use may lead to changes in the human epigenome, specifically affecting DNA methylation levels. These epigenetic changes, which do not alter the genomic sequence but influence gene activity, were linked to both recent and cumulative cannabis use. The research identified numerous DNA methylation markers associated with cannabis, some of which are also linked to tobacco use, suggesting shared epigenetic regulation. While the study provides insights into potential health impacts, it does not establish a direct causal relationship between cannabis use and health issues.
