A study from Israel looking into how marijuana use affects migraines showed that continued exposure to the drug may reduce the frequency of these bouts in the long term.

Published in the journal Brain Sciencesthe study surveyed 145 patients between the ages of 34 and 54, all of whom had been treating their migraines with medical marijuana for at least the past three years.

The study found that 61% of subjects reported that their monthly migraines had been cut in half. It also found that those subjects who did have reoccurring migraines suffered less impairment than usual, had better sleep patterns, and were consuming less medications in order to treat their symptoms.
