The use of medical marijuana for migraines is not a new concept. A 1998 study by the neurology department of the Western Montana Clinic explains that cannabis has been used for centuries to manage the effects of migraines. Ancient Greek, Chinese, Indian, Roman, and Egyptian literature all make reference to cannabis's efficacy for headaches, and it was the remedy of choice for migraine treatment well into the mid-twentieth century.
Tension headaches are the most common kind of headache that are associated with migraines. They can be triggered by fatigue, flu, alcohol use, eye strain, emotional stress and anxiety, insomnia, or excessive smoking. This type of headache is the result of the tightening of muscles in the neck and scalp, and medical marijuana, which helps in the relaxation of these muscles, can help manage the headache.
The use of cannabis may also help reduce the frequency of headaches since it can act as a prophylaxis or preventive measure. Usually, those who suffer from migraines have very little recourse for the treatment of this condition. Available medications often have unpleasant side effects which tend to cancel out any perceived benefits.
Cannabis acts as an analgesic and can help in the reduction of the pain from migraines. The reduction of endocannabinoids is suspected to be an underlying reason for migraines. A migraine trigger sets off a chemical reaction in the brain, causing the release of endocannabinoids to maintain balance. In individuals where this component is lacking, a dilation of blood vessels will result in intense migraine pain, which may explain the therapeutic benefits of cannabis in managing migraine.
