In a promising step for people who suffer from headaches, a study published in the Journal of Pain found that marijuana reduces migraine and headache pain by almost half. Carrie Cuttler, a Washington State University (WSU) assistant professor of psychology, led the study, which was the first of its kind to use data from patients using cannabis in real-time. Cannabis is a common treatment for headaches and migraines, especially in states where medical cannabis is readily available. Despite its popularity among headache and migraine patients, research on this subject is limited. Cuttler’s study aimed to identify the effects of various doses of cannabis concentrate and flower inhalation on headache and migraine severity.
