Medical cannabis treatment was associated with increased white matter coherence in a new peer-reviewed study conducted by researchers at Harvard Medical School and published in the journal Cannabis and Cannabinoid Research.
As noted by the study’s abstract, which was published online ahead of print by the National Institute of Health, previous studies have demonstrated abnormal white matter (WM) microstructure in recreational cannabis consumers. However, “the long-term impact of medical cannabis (MC) use on WM coherence is unknown.”
Accordingly, “this study assessed the longitudinal impact of MC treatment on WM coherence.”
As part of a larger, longitudinal investigation, patients interested in treating at least one medical condition with commercially available cannabis products of their choosing were assessed before initiating medical cannabis use and following three and six months of treatment.
