Researchers at Harvard University have published a new study finding that medical cannabis patients, “demonstrated significant improvements on measures of executive function and clinical state over the course of 12 months; verbal learning/memory performance generally remained stable.”
In simpler terms, the Harvard study found that over a year, patients who were using medical cannabis, mainly in the form of CBD, were seen to have sustained improvement in their cognitive abilities – verbal learning and memory. There was a strong correlation between improved cognitive ability and better sleep, mood and less anxiety.
The study looked at patients who had little or no history of cannabis use and followed their cognitive health over a 12 month period. The researchers concluded that, “results extend previous pilot findings, indicating that MC [medical cannabis] patients may exhibit enhanced rather than impaired executive function over time.”
