A new study says medical marijuana, unlike recreational marijuana, may actually improve cognitive functioning in adults, rather than impair it.
The study, led by McLean Hospital’s Staci Gruber and published in Frontiers in Pharmacology, found that after three months of medical marijuana treatment, patients performed certain cognitive tasks better than they did before treatment began. Specifically, Gruber explained in a statement, they saw improved performance in skills managed by the frontal cortex, which is responsible for thinking, problem solving, and planning.
