Summary

Retrospective cohort study on medical cannabis in migraine (n=121 adults, Colorado 2010–2014). Migraine frequency decreased from 10,4 to 4,6 attacks/month (p<0,0001). Positive effects in 48 patients (39,7 %): migraine prophylaxis with frequency reduction (24 patients, 19,8 %) and attack termination (14 patients, 11,6 %). Inhaled forms frequently used for acute treatment. Negative effects in 14 patients (11,6 %), mainly somnolence and dosing difficulties with edibles.
