A study from researchers at the University of New Mexico has found that more than nine out of 10 migraine patients reported that inhaled cannabis provided relief for their symptoms. A report on the research, titled “Alleviative effects of cannabis flower on migraine and headache,” was published this month in the Journal of Integrative Medicine.
To conduct the study, researchers tracked the effects of inhaled herbal cannabis on the symptoms experienced by 699 migraine sufferers over a period of 32 months. Participants self-administered cannabis while at home and reported their use and its effect on symptoms via the smartphone application Releaf. The intensity of pain related to migraine or headache was measured on a scale of zero to ten prior to and immediately following cannabis consumption.
“According to the current results, cannabis flower appears to be effective at reducing headache- and migraine-related pain intensity for most people that choose to use it,” the authors of the study wrote.
“It seems possible that the use of cannabis flower, combined with other behavioral modifications, might offer some patients a natural, safer, and more effective treatment regimen, compared to the use of some conventional prescription pharmaceuticals,” they added.
The study found that 94% of participants reported relief of symptoms within two hours of cannabis inhalation. On average, study participants experienced a reduction of 3.3 points on the ten-point scale. Varieties of cannabis with a THC content of 10% or higher were found to be most effective at relieving migraine symptoms. Males tended to achieve greater relief than females, and younger participants reported greater benefit than older patients.
