Migraine headaches can be extremely severe and debilitating. Many of the medications currently used for migraine headaches have significant side effects and often do not prevent or relieve all of the symptoms.
Marijuana was used to treat migraine headaches for many years in the nineteenth century, however due to the political climate and attitude towards marijuana in the twentieth century, it was not researched or promoted as an effective treatment for migraines.
Recent research has shown that THC, the active ingredient in medical marijuana , inhibits the release of serotonin from the blood of migraine sufferers during an acute attack, thereby reducing symptoms of pain. Although further scientific research is needed, many patients are using medical marijuana safely and effectively to prevent and treat their migraine headaches.
