Study Finds Medical Marijuana Treatment Reduces Use of Opioids
On March 22, 2016, the University of Michigan announced that a recent study conducted by the U-M School of Public Health and Medical School found that patients who treated chronic pain with medical marijuana had a 64 percent reduction in their use of prescription opioids.
Using an online questionnaire, the study’s researchers undertook a cross-sectional retrospective survey of 244 medical marijuana patients suffering from chronic pain who purchased their medical marijuana from the Om of Medicine, a legal dispensary in Michigan, between November 2013 and February 2015. The questionnaire collected demographic info, modifications in opioid use, types of medication used, side effects before and after initiating use of medical marijuana and quality of life.
Of the 244 medical marijuana users, 185 completed the questionnaire so only the completed questionnaires were used to calculate the study’s results; among those, medical marijuana use was associated with a reduction in medication side effects and medications used, a 64 percent reduction in use of prescription opioids and 45 percent of participants reported an improved quality of life.
