The review article shows encouraging data on medicinal cannabis’s therapeutic effects on alleviating migraines in all of the studies reviewed. Beneficial long-term and short-term effects of medicinal cannabis were reported. It was effective in decreasing daily analgesic intake, dependence, and level of pain intensity. Some patients experienced a prolonged and persistent improvement in their health and well-being (both physically and mentally) after long-term use of medicinal cannabis. Overall, patients reported more positive effects rather than adverse effects with medical cannabis use. Chronic pain and mental health are the two reasons where medical cannabis is used often. It is found that some medical providers are hesitant to recommend medical cannabis due to a lack of current evidence, medical professional training, and a lack of uniform medical cannabis use guidelines.
