What is Migraine?

Migraine is a common neurological condition that typically presents as a severe headache lasting between 4 and 72 hours. Many people report throbbing pain that gets worse with activity but not everyone will have a headache. People suffering a migraine may experience nausea and vomiting as well as sensitivity to light or sound. Other symptoms can include visual disturbances, numbness, tingling, weakness, confusion, dizziness or difficultly speaking.

How is it commonly treated?

Migraine is often treated with specific migraine medications and painkillers. Other remedies used to help relieve symptoms include caffeine, hot or cold packs, being in a calm or low-light environment and relaxation techniques. Some people who experience frequent, long-lasting or severe migraines may be prescribed preventative medication to reduce the impact of their symptoms.

Migraine and Medical Cannabis


Surveys and studies report encouraging data indicating that using medical cannabis can help reduce migraine symptoms, severity and frequency as well as improve sleep quality and reduce dependence on painkillers. Some people report an improvement in their physical and mental health and wellbeing after long-term use of medical cannabis and generally the effects of use are reported to be more positive than adverse. Despite mixed findings regarding its effectiveness, there appears to be consensus for the use of medical cannabis when first and second line treatments fail. Future controlled studies are needed to fully investigate the effects of medical cannabis on migraine.
